Saharan dust storms have repeatedly impacted weather, air quality, and public health across the Americas, including urban centers such as San Antonio, Texas.

These events are characterized by the trans-Atlantic transport of fine dust particles from North Africa, which can travel over 4,000 miles and reach regions as far-flung as Texas, Florida, the Gulf Coast, the Caribbean, Central America, and even parts of Europe .

The dust plumes are most common during the summer months, when the Saharan Air Layer (SAL)—a mass of hot, dry, and dusty air—moves westward, affecting local weather, air quality, and public health .

**Impacts on Weather and Air Conditions** Saharan dust storms significantly degrade air quality by increasing concentrations of fine particulate matter (PM2.5 and PM10), which can reach hazardous levels.

For example, during a dust event in Athens, PM10 concentrations soared to 700 µg/m³, far exceeding the European limit of 50 µg/m³, illustrating the potential severity of air quality degradation during such storms .

In San Antonio, dust events result in hazy skies, reduced visibility, and moderate air quality levels that can exacerbate health problems in vulnerable populations .

The dust also carries harmful bacteria and fungi, increasing the risk of respiratory infections and allergic reactions .

Weather patterns are also altered by Saharan dust.

The SAL contains about 50% less moisture than typical atmospheric conditions, which suppresses cloud formation and precipitation, leading to drier and hotter conditions in affected areas .

In Central Florida, for instance, dust events have been associated with above-average temperatures reaching into the mid-90s and a significant reduction in rainfall .

In San Antonio, the arrival of Saharan dust can cause a milky appearance in the sky, enhance the colors of sunrises and sunsets, and contribute to increased heat and reduced rain chances .

Occasionally, dust can interact with tropical moisture, leading to sudden rain events or flash flooding, though this is less common .

The SAL also suppresses hurricane and tropical storm development in the Atlantic by introducing dry, stable air that inhibits the moisture necessary for storm formation .

This effect can reduce the number and intensity of hurricanes during the season, indirectly affecting weather patterns in the Americas .

**Negative Impacts** The most significant negative impacts of Saharan dust storms are on public health, air quality, and urban infrastructure.

Elevated levels of PM2.5 and PM10 are linked to increased hospitalizations for respiratory and cardiovascular illnesses, particularly among individuals with pre-existing conditions such as asthma, COPD, or allergies .

In Barbados, for example, asthma incidence has increased 17-fold since the 1970s, with about 20% of the population affected and many experiencing worsened symptoms during heavy dust days .

In Texas, dust events have been linked to increased respiratory problems and greater reliance on rescue inhalers .

The dust also carries microbial contaminants, including bacteria and fungi, which can cause allergies and more severe health effects .

Air quality degradation is accompanied by reduced visibility, which poses risks for traffic safety.

The orange haze from dust can impair drivers’ vision, increasing the likelihood of accidents .

Accumulation of dust on vehicles can obscure license plates and other important markings, complicating traffic enforcement and safety .

In regions like the Coachella Valley, persistent haze from dust has led to serious health and economic consequences .

The power grid and infrastructure can also be affected.

Dust storms may cause power fluctuations or outages, and it is recommended to turn off air conditioning systems during such events to prevent damage .

Increased temperatures and reduced rainfall can raise energy demand for cooling, potentially straining the power grid .

Socio-economic impacts include increased healthcare costs due to respiratory illnesses, reduced productivity from sick days, and negative effects on tourism as dust storms deter visitors and reduce outdoor activities .

Agricultural impacts are also notable; in Cuba, Saharan dust arrival has been linked to decreased rainfall and increased temperatures, adversely affecting crops such as fruit, rice, and sugar cane .

**Positive Impacts** Despite the predominantly negative effects, Saharan dust storms provide ecological benefits by supplying essential nutrients such as iron and phosphorus.

This nutrient input fertilizes ecosystems like the Amazon rainforest and marine environments, promoting biodiversity and ecosystem productivity .

The dust also enhances the colors of sunrises and sunsets, creating visually striking natural displays .

The suppression of hurricane development by the SAL can be considered a positive effect, as it may reduce the risk of destructive storms in the Atlantic and Gulf Coast regions during active hurricane seasons .

**Geographical Areas Impacted** Saharan dust plumes have affected a wide range of regions in the Americas: - **Texas (including San Antonio and Houston)**: Experiences degraded air quality, increased temperatures, and health advisories during dust events .

- **Florida and Gulf Coast**: Noted for hotter, drier conditions, reduced rainfall, and air quality impacts .

- **Caribbean (Barbados, Cuba, Bahamas)**: Reports increased asthma rates, respiratory issues, reduced rainfall, and agricultural impacts .

- **Central America (El Salvador)**: Experiences intensified heat, reduced air quality, and health advisories during dust events .

- **Coachella Valley, California**: Persistent haze and air quality degradation with health and economic consequences .

- **Europe (Spain, UK, Ireland)**: Occasional dust transport causes red skies, "blood rain," and health warnings .

**Appropriate Preparations and Mitigation Strategies** To mitigate the impacts of Saharan dust storms, city planners and public health officials should implement a multi-faceted response: - **Public Health Advisories and Community Awareness**: Issue timely warnings to vulnerable populations, advising them to stay indoors, limit outdoor activities, and use air purifiers or masks during dust events .

Public education campaigns should inform residents about the risks and protective measures .

- **Air Quality Monitoring and Alerts**: Establish continuous air quality monitoring systems to provide real-time data and alerts, enabling residents to take appropriate precautions .

Implementing dust warning systems, as practiced in Trinidad, can help vulnerable populations prepare .

- **Traffic and Infrastructure Management**: Enhance traffic safety by increasing signage, issuing public alerts, and adjusting speed limits during dust events .

Encourage the use of public transportation to reduce accident risks .

Prepare the power grid for increased energy demand and potential disruptions, and advise residents to maintain air conditioning systems and turn them off during power fluctuations .

- **Urban Greening and Environmental Planning**: Promote urban green spaces and vegetation to help trap dust and improve air quality .

Manage construction sites to minimize dust emissions .

Content: Older Barbadians being diagnosed with asthma Loop Barbados

The content originally appeared on: Barbados News

Head of the Queen Elizabeth Hospital’s Respiratory Unit, Dr Dawn Alleyne, says more Barbadians are being diagnosed with asthma later in life, in their 40s and 50s.

Dr Alleyne, who is a Pulmonologist/Intensivist and Head of the Department of Medicine at the hospital, said the incidence of asthma in the Caribbean, including Barbados, had increased 17-fold since the 1970s. She added these trends are correlated with the increase in Sahara dust plumes and the frequency of the dust in the atmosphere.

She further noted that about 20 per cent of the local population had asthma. This meant the condition was quite common.

Due to climate change, dust events have been increasing. The dust, which traditionally visits from June to August, is now being seen in March or April.

The Pulmonologist/Intensivist said traditionally in Barbados, persons presented with asthma in childhood and either grew out of it as they got older, or lived with it as adults. However, this has changed.

“On a day-to-day basis when we conduct clinics, either [in my private practice] or at the hospital, I meet lots of people with severe lung diseases of all types, especially people with asthma. And several of my asthmatic patients have recorded quite clearly in their diaries that they’ve had challenges when we get the situations where we have cars covered in grey dust. Generally, those are the heavy Sahara dust days.

“A lot of the patients are now having to reach for their rescue inhalers, the Ventolin and Berotec inhalers because the asthma condition which generally has been stable, seems to deteriorate during the periods of times when we have lots of dust in the atmosphere,” Dr Alleyne stated.

The respiratory expert shared that persons usually presented with a gamut of symptoms when dust events occurred. These include itchy eyes, runny nose, soreness of the throat, coughing, especially at night, and wheezing.

Those who have chronic lung diseases, such as interstitial lung disease and chronic obstructive lung disease, also complain of increase in shortness of breath on the days in which there is a heavy dust cover,” she said.

She added that people who are not asthmatics should pay close attention to symptoms, such as chest tightness, when there is exertion, allergic rhinitis, eczema, snoring at night or allergic conjunctivitis. These persons could have an increased risk of developing asthma, she stated.

Dr Alleyne noted the situation was not unique to Barbados but could be seen across the world wherever the Sahara dust is being disseminated.

“So, you look at studies from Spain, Italy, the United States, and the French Caribbean. Throughout these areas, people are reporting an increased incidence of Sahara dust plumes, increased incidence of deterioration of asthma control, and patients are being hospitalised for not only respiratory illnesses, but also cardiovascular illnesses. So, the Sahara dust situation really is one that we really need to look at, not just as a hazy day and a sunset that’s not quite clear but really the impact that it is having on health in general, and we need to take it quite seriously.”

In the case of cardiovascular diseases, she said research show that the dust seems to affect the cardiovascular system adversely.

She explained that while larger dust particles are usually deposited pretty high in a person’s airway, causing sneezing and coughing, the smaller ones had the potential to enter the bloodstream and cause inflammation, which can be a precursor to cardiovascular events.

Dr Alleyne also suggested that Barbados implement a Sahara dust warning system, much like the one that exists in Trinidad, where they give accurate accounts of the air quality index. She said it could help people with respiratory conditions prepare and protect themselves better.

“So, I’m hopeful that in the future, we’ll be able to get something that tells us these are the exact numbers and to give warnings to specific categories of people. I think that will be very helpful,” the Pulmonologist/Intensivist stated.

Content: Orlando weather: Heavy rain and frequent lightning within strongest storms

Today's high: 90 degrees
Tonight's low: 77 degrees

Main weather concerns:
Rain chances will begin earlier than usual today as showers and storms roll east through Central Florida from the Gulf this morning into the afternoon. Expect periods of heavy rain and frequent lightning within the strongest storms. Isolated flooding will be possible in areas that see multiple rounds of heavy rain. With earlier storm chances, we could see rain come to an end by late afternoon for most areas. In areas that don't see as much rain, highs will soar into the 90s allowing for triple digit heat index values. Stay cool!

BEACHES:
A sunny start to the day may quickly become rainy as storms move towards the Atlantic Coast this morning. Expect storms by lunchtime and lasting through late afternoon. A moderate rip current risk will also return this weekend so be mindful of where you swim! Highs will warm to near 90 with a light SW wind.

THEME PARKS:
Scattered showers and storms are expected beginning in the morning and lasting through mid-afternoon. This means you may need to dodge the rain and keep an eye on the radar today if heading to the parks. With earlier rain, it may not be as warm with more cloud coverage this afternoon. We'll likely see a high near 90.

OUTLOOK:
Saharan dust is expected to arrive to Florida late this weekend and last into next week. This may bring down the air quality, add haziness to the sky, and even lower rain chances some. It still appears that we will at least have scattered PM storms and highs climbing well into the 90s through next week.

TRACKING THE TROPICS:
It remains quiet in the tropics with no tropical development expected in the next 7 days. We will continue to monitor the Atlantic so keep with us at FOX 35!

CAMS monitors Saharan dust transport across western and central Europe

Aerosol forecasts from the Copernicus Atmosphere Monitoring Service present a big amount of Saharan mud transferring northwards throughout Europe over the following few days. CAMS continues to watch the Saharan mud transport following current forecasts that confirmed the very best values over western Europe between 15 and 17 March 2022. The CAMS forecasts additionally present degraded air high quality throughout giant components of Spain, Portugal and France associated to the Saharan mud transport.

Copernicus Atmosphere Monitoring Service (CAMS) forecasts since 11 March have been exhibiting a big plume of mud with very excessive values of aerosol optical depth (AOD) and mud concentrations travelling northwards throughout the Iberian Peninsula, France and central areas of Europe between 15 and 17 March. The trajectory of this mud plume has resulted in very excessive predicted floor concentrations of PM10 as much as 250 micrograms per cubic metre, though European Environment Agency measurements have been exhibiting values in extra of this at many websites throughout Spain on 15 March. This is larger than the EU beneficial 24-hour imply threshold of fifty micrograms per cubic centimetre.

CAMS tracks all levels of mud transport from the Sahara Desert yearly and has been monitoring the annual mud transport, from completely different supply areas throughout the desert, for the reason that starting of the 12 months. CAMS forecasts are offered at each the European and global scale, and function a instrument to assist residents, companies, and policymakers make knowledgeable selections on a steady foundation with 24/7 air high quality forecast information. Air high quality is recognised as being very important to human well being as excessive concentrations of mud can have well being impacts on the respiratory programs of all individuals within the affected areas and add to particulate matter air air pollution from native sources. Senior Scientist, Mark Parrington, on the ECMWF Copernicus Atmosphere Monitoring Service feedback: “In CAMS we use satellite and in situ observations in our air quality forecasts to be able to provide a continual and reliable source of information for monitoring air pollution events such as this. Long-range transport events such as this occur most years and the impacts of the current event is quite striking. While the dust will affect air quality in parts of southwest Europe, the larger scale impacts will be hazy skies or some surface deposition.” You can discover extra data on the CAMS monitoring of this 12 months’s Saharan mud season right here: https://atmosphere.copernicus.eu/saharan-dust-heads-north-cams-tracks-its-progress-nfAdditional air high quality information will be discovered within the Atmospheric Data Store (ADS):https://ads.atmosphere.copernicus.eu/cdsapp#!/dataset/cams-global-atmospheric-composition-forecasts?tab=overviewandhttps://ads.atmosphere.copernicus.eu/cdsapp#!/dataset/cams-europe-air-quality-forecasts?tab=overview

Content: Saharan dust reaches stunning levels in Atlantic. Here's what that means for hurricane season

Significant Saharan dust plumes are common in the Atlantic during the start of hurricane season. If levels of SAL maintain a steadiness after about Aug. 20, then there would be significant ramifications to both the amount of cyclones and their overall strength.

First, Europe that was socked in by record levels of dust from the Sahara Desert in Africa. The Atlantic appears to have now taken the lead, with dust levels not seen in years across parts of the basin.

Satellite measurements indicate intensive plumes of dust, called the Saharan Air Layer, across much of the eastern Atlantic. Traces of dust have even made the more than 4,000-mile journey to Florida and the Gulf Coast.

Sunrises and sunsets have been enhanced across the Sunshine State as the particles scatter typical colors, allowing hues of orange, yellow and red to dominate the sky.

Aside from the vibrant colors, something not falling from the sky is precipitation.

According to NOAA, the air surrounding the SAL has about 50% less moisture than the typical atmosphere. This means the presence of the SAL can be detrimental to cloud formation and thunderstorm activity.

Significant plumes of dust and dry air are common during the first months of the hurricane season and usually persist through mid-August.

A LOOK AT A PHENOMENON THAT COULD DERAIL AN ACTIVE HURRICANE SEASON

How Saharan dust impacts hurricane season

NOAA estimates that more than 180 million tons of dust leave the African continent every year, reducing thunderstorm activity and tropical cyclone formation.

Dry air and Saharan dust are perennial wild cards in tropical weather outlooks, as meteorology has yet to develop sufficient methods to forecast plumes weeks and months in advance.

Years with significant dust often experience reduced cyclone activity. Seasons with minimal dust typically rank at the top echelons of activity, thanks to increased moisture availability for tropical systems and warmer water temperatures.

The current season is a bit unusual as water temperatures started on the warm side across much of the basin, negating any minor effects from a dust storm.

Warm waters and limited exposure to dry air helped with the formations of AlbertoBeryl and Chris during late June and early July.

Since Beryl’s historic trek through the Caribbean and into the Gulf of Mexico, the basin has been relatively quiet, a likely product of the increase in dry air.

The trend for limited activity in the Atlantic basin is expected to continue for the foreseeable future, meaning that the next cyclone formation may be weeks away.

5 THINGS TO KNOW ABOUT THE SAHARAN DUST PLUME

During an average year, the fourth-named storm usually doesn’t form until about Aug. 15, meaning any formation during the next month will keep the season ahead of a typical schedule.

Despite the hostile conditions in the Atlantic, hurricane forecasters at Colorado State University maintain that 2024 will be a busy season in the Atlantic.

CSU released its updated outlook Tuesday, which calls for an additional 22 named storms, 11 hurricanes and five major hurricanes.

"This forecast is of above-normal confidence. We anticipate a well above-average probability for major hurricane landfalls along the continental United States coastline and in the Caribbean," CSU forecasters stated during their most recent tropical update. "As with all hurricane seasons, coastal residents are reminded that it only takes one hurricane making landfall to make it an active season."

The season runs through Nov. 30, but nearly 60% of cyclone formation occurs in August and September.

Breathing is going to get tougher as hotter temps mean more air pollution, says study

Not all pollution comes from people. When global temperatures increase by 4°C, harmful plant emissions and dust will also increase by as much as 14%, according to new UC Riverside research.

The research does not account for a simultaneous increase in human-made sources of air , which has already been predicted by other studies.

"We are not looking at human emissions of air pollution, because we can change what we emit," said James Gomez, UCR doctoral student and lead author of the study. "We can switch to electric cars. But that may not change air pollution from plants or dust."

Details of the degradation in future air quality from these have now been published in the journal Communications Earth & Environment. About two-thirds of the future pollution is predicted to come from plants.

All plants produce chemicals called biogenic volatile organic compounds, or BVOCs. "The smell of a just-mowed lawn, or the sweetness of a ripe strawberry, those are BVOCs. Plants are constantly emitting them," Gomez said.

On their own, BVOCs are benign. However, once they react with oxygen, they produce . As they're inhaled, these aerosols can cause and childhood asthma, as well as heart disease and lung cancer in adults.

There are two reasons plants increase BVOC production: increases in and increases in temperatures. Both of these factors are projected to continue increasing.

To be clear, growing plants is a net positive for the environment. They reduce the amount of in the atmosphere, which helps control global warming. BVOCs from small gardens will not harm people.

"Your lawn, for example, won't produce enough BVOCs to make you sick," Gomez explained. "It's the large-scale increase in carbon dioxide that contributes to the biosphere increasing BVOCs, and then organic aerosols."

The second-largest contributor to future air pollution is likely to be dust from the Saharan desert. "In our models, an increase in winds is projected to loft more dust into the atmosphere," said Robert Allen, associate professor of Earth and Planetary Sciences at UCR and co-author of the study.

As the climate warms, increased Saharan dust is likely to get blown around the globe, with higher levels of dust in Africa, the eastern U.S., and the Caribbean. Dust over Northern Africa, including the Sahel and the Sahara, is likely to increase due to more intense West African monsoons.

Both organic aerosols and , as well as sea salt, , and sulfate, fall into a category of airborne pollutants known as PM2.5, because they have a diameter of 2.5 micrometers or less. The increase in naturally sourced PM2.5 pollution increased, in this study, in direct proportion to CO2 levels.

"The more we increase CO2, the more PM2.5 we see being put into the atmosphere, and the inverse is also true. The more we reduce, the better the air quality gets," Gomez said.

For example, if the climate warms only 2°C, the study found only a 7% increase in PM2.5. All of these results only apply to changes found in air quality over land, as the study is focused on human health impacts.

The researchers hope the potential to improve air quality will inspire swift and decisive action to decrease CO2 emissions. Without it, temperatures may increase 4°C by the end of this century, though it's possible for the increase to happen sooner.

Gomez warns that CO2 emissions will have to decrease sharply to have a positive effect on future air quality.

"The results of this experiment may even be a bit conservative because we did not include climate-dependent changes in wildfire emissions as a factor," Gomez said. "In the future, make sure you get an air purifier."

RED DUST

Urgent heatwave warning as plume of bizarre Sahara weather hurtles towards Ireland amid soaring temperatures

IRELAND will continue to sizzle under scorching temperatures this week, with experts predicting thermometers could spike as high as 26C.

However, a cloud of 'Saharan Dust' is expected to plume over the country, leaving red-coloured dirt in its wake.

The bizarre weather event, which is not uncommon in Europe but rarer in Ireland and the UK, will be dispersed over parts of Ireland this week.

And it is expected to come down onto Ireland alongside rain showers, mainly in the Southwest.

The dust can cause problems for people who are vulnerable to poor air quality, such as those who have asthma.

Alan O'Reilly from Carlow Weather said: "Latest high resolution charts showing risk of showers early tomorrow, mainly in the Southwest.

"You can expect a lot of Saharan dust to come down with them again."

Tomorrow is expected be another warm or very warm day as the country enjoys a moderately dry day in many areas alongside spells of hazy sunshine.

Met Eireann bosses warned that those in the southwest and west will experience a few showers and said: "The odd thundery downpour is possible."

Temperatures could reach as high as 26C in some areas, whilst some will bask under 22C heat.

It will be warmest away from east and south coasts, in moderate easterly breezes.

Tuesday night will be another "warm and muggy" night with temperatures of 14C to 17C.

Most areas will stay dry and clear, but some isolated showers may develop.

Looking towards the rest of the week, Met Eireann said: "Very warm, both by day and night with the increasing likelihood of thundery showers breaking out."

Wednesday will not be as sunny as the days before, with cloud building at times.

There will be also be scattered showers, some of which may turn heavy.

It is expected to be "very warm and humid" with top temperatures reaching an impressive 22C to 26C again.

On Wednesday night, it will be sultry again with temperatures not falling below 15 to 18 degrees as a southerly airflow persists.

Some thundery showers will occur, with the east and southeast most at threat.

The conditions will take a major turn on Thursday, but the hot temperatures show no sign of dropping.

Scattered heavy or thundery showers will spread across the country, alongside warm or very warm sunshine.

Temperatures will once again go as high as 20C to 26C, warmest in the east and northeast.

There will be patchy rain and some mist in parts overnight with lows of 13C to 18C degrees.

Saharan dust inundates Athens Wednesday morning

The African dust microparticles that blanketed southern Greece reached shocking concentrations in Athens of up to 700 µg/m3 on Wednesday morning when the European limit is 50 µg/m3.

The Saharan dust, called Minerva Red, started to recede as of noon, thanks to west-northwest winds.

Research by the Athens Observatory and the University of Crete shows that African dust has been arriving in Greece for at least 4,000 years.

“Studying especially the last 20 years, what we see is that dust transport episodes are characterized by periodicity, with intense phenomena every 3-5 years. There does not seem to be any upward trend, on the contrary in recent years, after 2018, when there was an upsurge, there was a recession,” said Nikos Michalopoulos, director of research at the observatory.

Saharan dust mainly arrives in spring, depending on the southerly winds. In recent years, southerly winds have prevailed on approximately 30% of the days in February, March and April.

Local leaders urge SCAQMD to acknowledge and help address worsened air quality conditions post-Hillary

If you think the Coachella Valley's air quality has worsened following Tropical Storm Hilary, you're not alone.

The Coachella Valley Association of Governments has also taken notice and is pushing for some new solutions to all the wind-blown dust most Coachella Valley residents agree has gotten worse following the August 2023 storm.

At a recent meeting with the South Coast Air Quality Management District, local leaders say they were told that Coachella Valley air quality measurements had returned to what was considered normal by that agency's standards.

Local leaders though say that's simply not true.

CVAG Executive Director Tom Kirk told KESQ News Channel 3, "They continue to say it has returned to normal me and others disagree. Those who visit know. It has serious health and economic consequences."

He also noted the impacts to the public’s welfare are clearly noticeable as aerosolized particles produce a persistent haze that remains visible well after higher winds have passed.

In a letter sent to the SCAQMD Kirk suggested the agency's monitoring methods are inadequate and do not account for high dust pollution numbers that are often elevated in our afternoon and evening hours, but not for a full 24-hour period, therefore considered okay.

The letter stated, "Because these high levels did not coincide with a midnight-to-midnight 24-hour period, these days might go unreported as an exceedance of federal air quality standards. However, these concentrations represent severe exposure across two afternoons and evenings, exposing residents and visitors to hazardous air quality conditions."

READ CVAG's FULL LETTER TO SCAQMD HERE.

Riverside County 4th District Supervisor V. Manuel Perez said, "South Coast does care I think about how we can work together to better air quality for our people."

Local cities and Caltrans responded to the increased wind-blown dust threat by applying soil stabilizer wherever possible around low-lying areas and sought financial relief from the Federal Emergency Management Agency.

Another meeting to discuss air pollution concerns from wind-blown dust was scheduled for June 18.

Kirk, Perez, and other local leaders representing every city in the Coachella Valley say they hope SCAQMD will offer more aid and monitoring for potential solutions.

Content: GMA calls on public to wear nose masks

By Dennis Peprah

Sunyani, Feb. 16, GNA – The Ghana Medical Association (GMA) has urged Ghanaians to go back to wearing nose masks to reduce their exposure to dust because of the intensification of the harmattan weather condition.

A statement signed by Dr Frank Serebour, the President of the GMA, sighted by the Ghana News Agency, asked the public to stay hydrated by drinking a lot of water throughout the day.

“The increased dust and general dry weather conditions have seriously affected human health, possibly leading to increased respiratory conditions,” it said.

“People with asthma and other chronic respiratory conditions may suffer acute attacks or worsening conditions.”

The statement therefore advised that persons with asthmatic conditions must endeavour to always carry their inhalers and take all prescribed medications.

Anyone who experienced signs and symptoms of respiratory conditions such as cough, painful swallowing, runny nose, chest pain or difficulty in breathing should immediately report to the nearest health facility, it advised.

It urged drivers to avoid over-speeding, especially on dusty roads and at night and the public must avoid bush burning or engaging in activities that could lead to bushfires.

Contractors must ensure that roads under construction are well watered to reduce dust pollution.

The SAL also suppresses hurricane and tropical storm development in the Atlantic by introducing dry, stable air that inhibits the moisture necessary for storm formation .

Content: Heavy rain potential this week in San Antonio with Tropical Storm Watches along Texas Coast

Rain around San Antonio will begin midday Wednesday, ending late Thursday

As we’ve been reporting, the National Hurricane Center is monitoring the Gulf of Mexico for tropical storm development. Regardless of development, the impact to San Antonio will be times of heavy rainfall Wednesday and Thursday this week. Here’s what you need to know:

KEY POINTS

  • Latest indications continue to suggest that this system would move west towards Mexico, with the higher wind impacts staying well south of our area
  • However, the area of low pressure will throw deep, tropical moisture and rain north into San Antonio and South Central Texas
  • As of now, scattered tropical downpours are forecast to develop on Wednesday and Thursday, along with cooler temperatures
  • The highest rain totals will be near the coast, but totals in the range of at least 2″-5″ are looking possible closer to San Antonio

HOW MUCH RAIN?

Highest rainfall totals will be near the Texas Coast with up to 7″of rain possible from Tuesday through Thursday. Farther inland, near San Antonio, the number is closer to 2″ to 5″. In the Hill Country, 1″ to 3″.

Please be mindful that it won’t be raining all day Wednesday and Thursday. Rather, there will be times of heavy rain. Still, this could lead to street flooding so please be cautious and check the radar before driving Wednesday and Thursday.

THE LATEST

As of Monday evening, “Potential Tropical Cyclone One” (PTC 1) was located over the Bay of Campeche and is expected to strengthen into a weak tropical storm named Alberto with winds of 45 mph by Wednesday. It is anticipated to stay relatively weak and make landfall in northeastern Mexico by Thursday morning.

If the storm were to take a more northerly track than anticipated, it would result in gusty winds and minor storm surge along Coastal Texas. As a result, Tropical Storm Watches have been issued for areas from South Padre Island to Galveston/Coastal Houston.

IMPORTANT: Even though San Antonio and Texas are not in the direct path of the potential tropical storm, we will still see impacts from this system, mainly in the form of heavy, tropical downpours. Times of drought-denting rain would begin midday Wednesday and end by Thursday evening.

TROPICAL STORM NAMES FOR 2024

While details will still need to be fine-tuned in regards to how this system will evolve, we know that it’s forecast to be a busy season across the Atlantic Basin. Here is the list of names that will be used for tropical storms and hurricanes this season.

Prepping your air conditioner ahead of a dust storm

Strong winds are expected to sweep through the Valley this weekend, bringing dust that will impact our air quality.

Even after the storm, lungs and good health can suffer long after the winds die down.

Air conditioning is often a necessity when living in the desert. For many, it’s running constantly during our hot summers. But when high winds gusts make their way into the Valley, you might need to think twice about keeping the AC on.

“If you see power fluctuations during the sandstorm, shut your air conditioner off," says Daniel Warren McIntyre, President of All Valley Air. "If the voltage your power in your house starts to go up and down. For the simple reason that is the number one killer of compressors is low voltage.”

McIntyre has been President of All Valley Air in Palm Desert for 18 years. He’s seen it all when it comes to cooling and heating systems.

Fortunately, he tells us your outdoor AC units are likely safe during a dust storm. “Dust doesn't necessarily bother the outdoor units. They're made to run in weather, no doubt, they're tested rigorously for that so that they have longevity.”

Be sure to double-check your windows are closed and sealed as well. “It will find its way and keep your windows closed. No doubt about that," McIntyre explained, "A lot of people don't realize even though we have beautiful blue skies, just how much dust is in that air.”

Once the dust storm passes through, McIntyre says there’s a few things you should keep in mind.

“It's a good idea to twice a year have your unit maintenanced, change the air filters in there at least once a month.... Because if the evaporator coil gets restricted, the your efficiency goes down and it costs you more money electricity.”

Other tips to remember:

  • Be sure to clean your air conditioner from time to tie
  • Increase ventilation, like keeping vents and fans on to keep air moving & keep dust from settling
  • If your allergies tend to act up during dust storms, it may be a good idea to get an air purifier or scrubber

Content: Hurricane Killer? Here are some things you may not know about Saharan dust

Dust from Africa moves across the Atlantic every year from late spring to early fall

It’s a common visitor in the summer months: dust from the Saharan Desert. Hazy skies and occasional allergies are common issues caused by the dust. But did you know that this layer of dust is more interesting than it appears? Here are some things you may not know about Saharan dust:

KEY TAKEAWAYS

  • Millions of tons of dust are transported across the Atlantic every year
  • Nutrient-rich Saharan dust plays a crucial role in the global ecosystem
  • Dust suppresses hurricane development

WHOLE LOTTA DUST!

Every year, from late spring to early fall, trade winds transport 180 million tons of dust from the Saharan Desert across the Atlantic Ocean. Impressively, that’s as much as 4.5 million 18-wheelers full of dust!

NATURE’S BEST FRIEND

Saharan dust is often rich in nutrients like iron and phosphorus. As the dust settles over the ocean, it fertilizes algae and plankton, allowing them to grow and flourish in an otherwise barren environment. These organisms are vital sources of food for ocean life.

Similarly, as the dust settles over land, areas like the Amazon rainforest benefit from the extra nutrients.

HURRICANE EXTINGUISHER

The African dust that moves across the Atlantic Ocean is also called the Saharan Air Layer (SAL). The SAL occurs in waves at the same time as Atlantic hurricane season, from June through November.

It’s known that the SAL limits hurricane development and strength. This is because tropical storms like hurricanes need deep, rich moisture from the surface to the top of the atmosphere to survive. Since the air carrying Saharan dust is usually dry, it can prevent storms from forming and suppress existing storms from growing and strengthening.

DUST’S IMPACT ON TEXAS

While a dense plume of dust sometimes causes minor allergy-like symptoms for some, the most noticeable impact is on Texas skies. A haze often forms on the horizon, giving an ordinarily clear, blue sky a milky hue during the day.

At sunrise and sunset, the horizon can appear brilliantly orange because, with dust in the air, sunlight has more particles to bounce off.

Saharan dust inundates Athens Wednesday morning

The African dust microparticles that blanketed southern Greece reached shocking concentrations in Athens of up to 700 µg/m3 on Wednesday morning when the European limit is 50 µg/m3.

The Saharan dust, called Minerva Red, started to recede as of noon, thanks to west-northwest winds.

Research by the Athens Observatory and the University of Crete shows that African dust has been arriving in Greece for at least 4,000 years.

“Studying especially the last 20 years, what we see is that dust transport episodes are characterized by periodicity, with intense phenomena every 3-5 years. There does not seem to be any upward trend, on the contrary in recent years, after 2018, when there was an upsurge, there was a recession,” said Nikos Michalopoulos, director of research at the observatory.

Saharan dust mainly arrives in spring, depending on the southerly winds. In recent years, southerly winds have prevailed on approximately 30% of the days in February, March and April.

Content: Motorists are being warned of a potential threat to vehicles as weather maps indicate that a sizzling 'Saharan Plume' is approaching. The UK has so far experienced a week of wet and windy conditions, but hope is in sight for those seeking sunnier spells, as the temperatures are forecast to rise in the coming days.

Despite a week plagued by unpredictable weather, characterised by muggy temperatures and frequent rainfall, next week's forecasts hint at an upturn. From Sunday May 19 to Tuesday May 21, it's predicted we'll see a return of balmy temperatures and plenty of sunshine, making way for a potentially splendid half term break.

Predictions suggest the best of the weather will shine on the Midlands, Northeast England and Yorkshire, where certain regions are anticipated to bask in highs of around 23C.

Things are set to heat up even further come May 26, with London, the southeast and the south coast potentially seeing mercury levels touch a sweltering 24C. Meanwhile, the rest of the country is expected to stay comfortably above 20C.

Netweather reports that most of England can look forward to temperatures hovering between 22C and 24C. While a bit cooler, Wales will still have some spots surpassing 20C, with Northern Ireland showing a similar trend, reports the Mirror.

Adding their input, the Met Office has issued its own forecast for the upcoming week. Their prognosis for May 19 to May 28 is characterised as "changeable", with temperatures predicted to be "generally around or just above average."

The current forecast indicates: "Temperatures will be generally around or just a little above average. With winds tending to be light, it will feel warm in sunnier areas. As we head further into the following week, confidence lowers into the following week. On balance, a continuation of the showers in the south seems most likely, with the north continuing to see the best of any drier weather. Temperatures will probably remain a little above average."

There's growing speculation about another Saharan plume potentially warming up the UK soon. While the prospect of warmer weather might be welcome, it's important to note that such conditions can also pose risks to both people and vehicles.

One significant hazard associated with a Saharan plume is the dust it carries, which recently wreaked havoc across mainland Europe last month. This natural occurrence enchanted many with its hazy skies and vibrant sunsets, yet it also escalated air pollution levels, surpassing some of the European Union's safety thresholds in various regions, including popular vacation destination Spain.

In southern and eastern parts of the country, residents experienced air quality that was four times over the healthy limit for PM10 particle contamination, posing a particular threat to individuals with respiratory conditions like asthma.

The Saharan dust also poses a risk to vehicles, as the thin layer of dust that typically settles on cars after desert weather can scratch paintwork and windows if not properly removed. To safely clean off the dust without causing damage, motorists are advised not to rub or wipe the dust away, but to thoroughly rinse their vehicle first, ideally using a pre-wash, followed by a snow foam soak and a thorough rinse.

Layer of Saharan dust will affect the Bahamas by the weekend

By EARYEL BOWLEG

Tribune Staff Reporter

ebowleg@tribunemedia.net

RESIDENTS are urged to “safeguard their health” as a plume of Sahara dust moves over the south-east Bahamas.

The Department of Meteorology said the dust will gradually move across the country this weekend.

It warned the dust could be problematic for people with allergies and respiratory issues.

“Sahara dust is made of sand, dirt, and other dust particles that are lifted into the atmosphere from the vast Sahara Desert in Africa,” the advisory said.

Acting director of meteorology Jeffrey Simmons told The Tribune the dust tends to appear around this time every year.

He said the dust has lingered around southeastern islands for the past week, prompting some to complain about allergies.

“That’s the reason, you know, why we put out this warning alerting people about it, people who have these allergy issues or any respiratory issues so that they could, you know, be aware of the impact this could have on them for this weekend and possibly going into another week or two,” he said.

San Antonians may want to stay indoors next week. Here's why.

A noticeable change in the air will arrive to the Alamo City next week.

SAN ANTONIO — San Antonio skies could look quite different next week but not in the way we're hoping for.

As San Antonians eagerly wait for rain to break our triple-digit temperatures another common occurrence will pick-up next week known as Saharan dust.

The dust is a combination of sand and dust traveling from North Africa across the Atlantic that peaking in late June through mid-August.

Light amounts of Saharan dust have arrived to the Alamo City this past week but will become more noticeable. Therefore, if you have asthma, COPD or any other type of respiratory illness you will want to stay indoors as much as possible during this time.

Timing of Saharan dust:

Monday - Little changes will be in the forecast as heavier amounts of dust remain over the gulf coast.

Credit: KENS 5 Weather

Tuesday - A large moderate level of Saharan dust will move into South Texas and San Antonio by late afternoon. San Antonians may notice hazy skies and trouble breathing if you're more sensitive to dusty air. But the dust doesn't stop here.

Credit: KENS 5 Weather

Wednesday - By mid-week Saharan dust ramps up continuing to build and push farther north stretching to the Dallas area. The continuing flow of the dust is partly due to a high pressure bringing a southeasterly flow to help pump the dust toward South Texas.

Credit: KENS 5 Weather

Thursday - As the week progresses dust levels continue to rise and could affect air quality levels. For those with any respiratory illnesses they should avoid outdoor activity including vigorous exercise. Also try to keep windows and doors closed. We will continue to monitor this development next week.

It is thought the dust which can be seen on vehicles and outside furniture is Saharan dust, which is a mixture of sand and dust from the Saharan desert in north Africa.

The dust swept across the country earlier this year, leaving cars in need of a clean.

A forecaster from the East Anglian-based Weatherquest said: "The Saharan Dust gets whipped up into the atmosphere and can be spread over quite a large portion of the world.

"The dust gets kicked up into the sky and is the winds in the upper part of the atmosphere are blowing north, the dust can be carried as far as the UK."

The dust particles then mix with rain clouds before falling to the ground as murky rain.

Saharan dust brings hot and dry weather to Central Florida on Sunday

Saharan dust brings temperatures above average and dry conditions across Central Florida on Sunday.

“So you probably heard about the Saharan dust that’s been making for those hazy sunrises and sunsets here in the past few days,” Meteorologist Chris Gilson said. “It’s also been leading to those lower rain chances allowing our temperatures to heat up into the mid nineties.”

Sunday’s high is 96 with a low of 75 and only a 10% chance of rain across Central Florida.

“A spot shower storm will be possible today but notice we’re seeing the reds and oranges, that’s all that dry air due in part to that Saharan dust that hangs around with us for today,” Gilson said.

The Saharan dust sticks around into early next week as the dry air and slim rain chances continue.

The dust is helping keep the tropics quiet for the next five to seven days, but we still have a long way to go until the peak of Hurricane season in September.

İZMİR

A massive dust storm from the Sahara Desert is expected to shroud the country, with experts warning citizens, especially those with respiratory disorders, to take precautions.

Professor Dr. Doğan Yaşar, a climate scientist, cautioned that a period of intense dust transport will begin on March 25.

"Red-colored desert dust laden with iron particles will arrive in large quantities," he explained.

"While this dust fertilizes the soil and benefits agriculture, it can also trigger allergy symptoms like dry cough and sneezing, especially for people with asthma or other lung conditions,” he said.

Yaşar emphasized the importance of wearing masks during this period. "People with lung diseases should wear a particle-retaining mask for three weeks, if possible," he advised. "Regular masks can offer some protection as well."

"A single pine tree produces 12 billion pollen. Thus, during this period, pollen multiplies very intensively in the air. When we inhale this, we experience discomfort. It is especially dangerous for people with lung diseases such as asthma," he added.

The dust storm is a natural phenomenon that occurs annually, transporting around two billion tons of dust from the Sahara to various parts of the world. The professor highlighted the ecological benefits of this dust, which acts as a natural fertilizer. However, he cautions that the concentrated dust can irritate airways and exacerbate allergies.

While the dust storm may cause temporary inconveniences, Yaşar reassured citizens that there's no need for alarm.

"The dust benefits agriculture, but it's important to be aware of the potential health risks, especially for those with respiratory problems," he concluded.

Saharan dust inundates Athens Wednesday morning

The African dust microparticles that blanketed southern Greece reached shocking concentrations in Athens of up to 700 µg/m3 on Wednesday morning when the European limit is 50 µg/m3.

The Saharan dust, called Minerva Red, started to recede as of noon, thanks to west-northwest winds.

Research by the Athens Observatory and the University of Crete shows that African dust has been arriving in Greece for at least 4,000 years.

“Studying especially the last 20 years, what we see is that dust transport episodes are characterized by periodicity, with intense phenomena every 3-5 years. There does not seem to be any upward trend, on the contrary in recent years, after 2018, when there was an upsurge, there was a recession,” said Nikos Michalopoulos, director of research at the observatory.

Saharan dust mainly arrives in spring, depending on the southerly winds. In recent years, southerly winds have prevailed on approximately 30% of the days in February, March and April.

Content: Havana, Cuba.- Cubans are entering the final days of July with a forecast of high temperatures, accompanied by little rain throughout the national territory.

In recent days, the heat punished the inhabitants of the Caribbean island, where through the Institute of Meteorology it was learned that in 38 of the 68 stations subordinate to the scientific entity, temperatures above 34 Celsius degrees were reported.

Meanwhile, the nightly broadcast of the National Television Newscast specified that in the eastern territory of Granma 39°C were registered on Saturday.

Behind it, the most overwhelmed towns were Colón in the western province of Matanzas with 37.2 °C; and Bainoa, in the also western province of Mayabeque, with 36.5 °C; while in the capital the thermometers marked 36 °C.

Days prior to the establishment of these temperature records for the current month, the Institute of Meteorology warned about the arrival of a cloud of dust from the Sahara on the island.

The experts explained that this phenomenon would cause a new decrease in rainfall and would maintain the feeling of great heat.

These clouds contain iron, silica, fungi, bacteria, viruses, various pathogenic mites, among other elements. They can cause acute respiratory diseases, allergies and skin problems.

Dust from the Sahara affects coral reefs, and fruit, rice, sugar cane, bean and other crops. It is caused by storms that occurred in the Sahara desert, coming out of the African continent.

It moves over the freshest and most humid marine air, and joining the flow of the trade winds, it quickly reaches the Atlantic Ocean, the Caribbean Sea, and the Gulf of Mexico.

Saharan dust brings hot and dry weather to Central Florida on Sunday

Saharan dust brings temperatures above average and dry conditions across Central Florida on Sunday.

“So you probably heard about the Saharan dust that’s been making for those hazy sunrises and sunsets here in the past few days,” Meteorologist Chris Gilson said. “It’s also been leading to those lower rain chances allowing our temperatures to heat up into the mid nineties.”

Sunday’s high is 96 with a low of 75 and only a 10% chance of rain across Central Florida.

“A spot shower storm will be possible today but notice we’re seeing the reds and oranges, that’s all that dry air due in part to that Saharan dust that hangs around with us for today,” Gilson said.

The Saharan dust sticks around into early next week as the dry air and slim rain chances continue.

The dust is helping keep the tropics quiet for the next five to seven days, but we still have a long way to go until the peak of Hurricane season in September.

Sahara desert dust storms carry harmful bacteria and fungi around the globe

We often dismiss springtime allergies as reactions to local pollen. Yet, something else might cause our sniffles and sneezes: a massive dust storms that originate thousands of miles away in Africa’s Sahara region.

These gargantuan dust plumes travel the globe every summer, carrying a cocktail of pollutants and potential pathogens across continents.

Dr. Shankar Chellam, a Texas A&M University professor is leading the charge to understand the biological hitchhikers within dust storms.

He and his team are working to determine what microbes, specifically bacteria and fungi, migrate with the dust and explore their potential impact on human health.

Hidden passengers in Sahara dust

“We all get allergies and potentially other more severe health effects when we breathe in dust, and it’s not fully known as to what causes those allergies,” said Dr. Chellam.

“Some people may think it is just the sand or clay minerals in the dust. Others think it is the metals or organics in the dust, and then some think it’s the bacteria and fungi.”

The Saharan dust cloud carries vast amounts of sand particles that transport bacteria and fungi.

Dr. Chellam’s research uniquely addresses how Saharan dust storms introduce these microbes into North America.

What the dust storm from Sahara tells us

Dr. Chellam and his team analyzed samples from a Saharan dust event that reached Houston in 2018. They measured metals, bacteria, and fungi to investigate any connections.

Fascinatingly, their findings revealed strong links between the biodiversity of the microbes and specific elements, especially calcium.

While these elements occur naturally in the Sahara, they also exist in our local environments. Pinpointing the exact origin of the dust and its cargo remains a challenge that scientists continue to tackle.

Our air – Not as empty as we think

Perhaps the most startling discovery is that even seemingly lifeless clouds of dust brim with biological activity.

“A key takeaway from this study is that a lot of biodiversity is not scientifically described. It doesn’t have a name, it can’t be cultured, and because it can’t be cultured, it’s difficult to study,” explained Dr. Daniel Spalink, assistant professor at Texas A&M.

The team’s high-tech DNA analysis allowed them to create an inventory of bacteria and fungi, even if the microbes themselves weren’t active.

Surprisingly, they found traces of several pathogens known to cause disease in humans, as listed by the World Health Organization (WHO).

“It doesn’t tell us if they are going to be able to infect us and make us sick,” Spalink cautions, “But at least the DNA of several pathogenic bacteria and fungi were identified in the African dust.”

Impact of climate change on Sahara dust

Climate change is altering weather patterns globally. This transformation affects dust storm behavior, leading to variations in their frequency and intensity.

In 2020, the United States experienced the most massive Saharan dust storm ever recorded, which experts named “Godzilla.”

This event highlighted the potential for increasing occurrences of such dust invasions. “The whole dynamics of the Saharan dust coming to Houston is primarily driven by atmospheric processes,” said Dr. Sourav Das, a former student of Dr. Chellam.

Global connection of Sahara dust

Sahara dust storm travels far beyond the borders of North America, affecting global environmental systems in profound ways.

This dust, originating from the vast Sahara Desert, embarks on transcontinental journeys that influence climate, ocean biology, and ecosystems far removed from its source.

The Saharan dust plays a critical role in climate regulation. As it travels across oceans and continents, it reflects sunlight back into space, cooling the Earth’s surface.

This natural phenomenon acts as a counterbalance to the warming effects of greenhouse gases, showcasing how desert dust can influence global temperatures.

However, the dust also carries microorganisms and nutrients, such as phosphorus, that fertilize remote ecosystems, from the Amazon rainforest to the Caribbean Sea, demonstrating nature’s complex nutrient cycles.

Benefits to oceans

Ocean biology benefits from the nutrient-rich dust as well. When Saharan dust settles on ocean waters, it delivers essential minerals that stimulate the growth of phytoplankton.

These microscopic plants form the foundation of the oceanic food chain, supporting a diverse array of marine life.

The influx of nutrients from the Sahara can thus boost marine productivity, affecting fish populations and the global fishing industry.

Disadvantages

The impact of Saharan dust is not universally beneficial. In ecosystems unaccustomed to the influx of foreign particles and nutrients, the dust can disrupt local environments.

For example, excessive dust deposition can smother coral reefs, blocking sunlight and hindering photosynthesis. This can stress coral ecosystems, leading to bleaching events and loss of biodiversity.

Moreover, the health implications of Saharan dust extend across continents. The dust carries not only nutrients but also pollutants and pathogens that can affect air quality and public health.

Communities in the path of these dust plumes may experience increased respiratory issues, allergies, and diseases, highlighting the need for global health monitoring and preparedness.

Study insights

It’s crucial to gather data across multiple dust events, spanning many years, to get a clearer picture of these airborne microbial communities and how they might transform over time.

While a lot remains unknown, research like this shines a spotlight on the hidden travelers swirling in the air we breathe — travelers who might be affecting our health in surprising ways.

The next time you catch a glimpse of a dust storm rolling in, remember the globe-trotting microbes it carries!

The findings of the study are published in Environmental Science & Technology.

UK holidaymakers have been issued a Spain travel warning as terrifying “blood rain” has hit the country that could disrupt flights. Tourists have been warned that visibility could be impacted due to the orange haze that the dust leaves in the atmosphere.

The Mirror reports that the weather alerts that cover most of the country may spark problems for people who already suffer from lung and respiratory conditions. This news has come after the cooler areas of Spain were hit with a heatwave as temperatures skyrocketed above 30C in some places. This change also produced a new episode of Saharan dust - known as a Calima - which is set to cover many Spanish hotspots for up to three days.

Weather experts have said that while some locations are still seeing rain, this water can merge with the dust to create 'blood rain'. According to Marta Almarcha on the eltiempo.es weather portal, this dust will not affect just the Iberian Peninsula, but other European countries as well - even reaching some Scandinavian countries.

According to the Met Office, blood rain “occurs when relatively high concentrations of red coloured dust or particles get mixed into the rain, giving it a red appearance as it falls”. They explained that it can be caused by strong storms whipping up dust and sand which then becomes airborne before getting “caught up in atmospheric circulation” before it falls to the ground with the rain.

On Sunday (7 April) the situation will be affecting the whole of the south and central peninsula of Spain especially Andalusia, Castilla-La Mancha, Extremadura and Madrid. Those with respiratory conditions should take the necessary precautions to protect themselves during this time, especially if they live in the parts of Spain where the haze is going to be most persistent.

Forecasts have predicted that the dust will clear up this week when an Atlantic front will push it eastward and change the winds. Weather forecasters predict temperatures will drop a little with rain most likely affecting Huelva, Seville, Cadiz and Cordoba.

Layer of Saharan dust will affect the Bahamas by the weekend

By EARYEL BOWLEG

Tribune Staff Reporter

ebowleg@tribunemedia.net

RESIDENTS are urged to “safeguard their health” as a plume of Sahara dust moves over the south-east Bahamas.

The Department of Meteorology said the dust will gradually move across the country this weekend.

It warned the dust could be problematic for people with allergies and respiratory issues.

“Sahara dust is made of sand, dirt, and other dust particles that are lifted into the atmosphere from the vast Sahara Desert in Africa,” the advisory said.

Acting director of meteorology Jeffrey Simmons told The Tribune the dust tends to appear around this time every year.

He said the dust has lingered around southeastern islands for the past week, prompting some to complain about allergies.

“That’s the reason, you know, why we put out this warning alerting people about it, people who have these allergy issues or any respiratory issues so that they could, you know, be aware of the impact this could have on them for this weekend and possibly going into another week or two,” he said.

Content: This weekend marks the peak of the Atlantic Hurricane Season. This is typically when the Atlantic is most active for tropical systems. This year, however, the Atlantic looks to be settling down, at least for the time being.

Not too long ago the Atlantic was busy with Hurricane Danielle, then Hurricane Earl forming. Both of those storms remained out in the open Atlantic away from the United States. Now that Danielle has faded and Earl is moving away, there are not as many areas to watch in the Atlantic.

The latest Tropical Update

For now, there is only one area of interest off the coast of Africa. This area only has a low chance of development over the next five days. This doesn’t mean that another storm won’t form in the days to come, but it is possible that we will see a lull in tropical activity.

Saharan dust continues to be a limiting factor for storm development. This dry, dusty air limits and chokes off thunderstorm development in the Atlantic. Thus limiting the number of tropical systems. For now, more Saharan dust is expected to move out into the open Atlantic, hindering any tropical development over the next few days.

While presently there are factors that are limiting tropical development in the Atlantic, there is still half of the season left to go. We still have time for conditions to change and for more storms to develop later on.

The Weather Authority will continue to monitor the topics and bring you the latest.

Content: Hurricane center begins tracking a system in the Caribbean

·2 min read

ORLANDO, Fla. — The National Hurricane Center has been jumping around the last few days tracking short-lived systems with the potential to form into a tropical depression or storm. Late Monday, the NHC began looking at the Caribbean Sea.

As of the NHC’s 8 p.m. Eastern time tropical update, a tropical wave located in the central Caribbean is forecast to move across Central America and emerge over the southwestern Gulf of Mexico where it could develop into the season’s next named system.

“Some gradual development of this system is possible thereafter as it moves slowly to the northwest or north-northwest over the southwestern Gulf of Mexico by this weekend,” said NHC hurricane specialist Philippe Papin.

The NHC gives the system a 20% chance of formation in the next five days.

The Caribbean system follows the NHC keeping track of a broad trough of low pressure in the mid-Atlantic late Sunday, but its chances of formation dropped to 0% by Monday morning. Over the weekend, the NHC tracked a system in the Gulf of Mexico, but it failed to form into more than a spate of showers and thunderstorms that drenched southeastern Texas. Before that, a system off the African coast showed some signs of development before environmental factors snuffed its chances.

Part of the reason for what prevents tropical storm development is the dry conditions in the Atlantic. A large migration of African dust, the Saharan Air Layer, or SAL, is the main reason tropical moisture isn’t at the ideal level for development. Large dust plumes are still pushing west of Africa and into the Caribbean, preventing the Atlantic basin from becoming a hurricane nursery, the National Oceanic and Atmospheric Administration’s SAL forecast shows.

Hurricane season is approaching its peak, which runs from mid-August to mid-October, with Sept. 10 recorded as the statistically most productive day of storms in the tropics.

So far, the 2022 season has seen three named storms: Alex, Bonnie and Colin. Based on historical averages, the fourth named storm of the year typically appears by Aug. 15. If a system were to emerge, it would receive the name Danielle.

Last week, the National Oceanic and Atmospheric Administration reaffirmed its preseason prediction of an above-average hurricane season with a range of 14 to 21 named storms. The NOAA expects most of those storms to emerge at the peak of the season.

Hurricane season ends on Nov. 30.

Saharan dust, which turns the skies orange and pink, has swept across East Anglia once again.

Weather experts have explained why cars have been left covered in dust after heavy rain at the weekend.

Cars across the area have been covered in dust, which has left some people looking to get their vehicles cleaned.

It is thought the dust which can be seen on vehicles and outside furniture is Saharan dust, which is a mixture of sand and dust from the Saharan desert in north Africa.

The dust swept across the country earlier this year, leaving cars in need of a clean.

A forecaster from the East Anglian-based Weatherquest said: "The Saharan Dust gets whipped up into the atmosphere and can be spread over quite a large portion of the world.

"The dust gets kicked up into the sky and is the winds in the upper part of the atmosphere are blowing north, the dust can be carried as far as the UK."

The dust particles then mix with rain clouds before falling to the ground as murky rain.

Heat relief heading for NY — other parts of US aren’t as lucky

After soaring temperatures baked the Big Apple this week, New Yorkers will see some relief in the coming days while other parts of the country won’t be so lucky.

“After a couple of toasty days up here in the Northeast that I am glad are behind us, we’re back to about average,” Fox Weather meteorologist Christopher Tate told The Post Saturday.

The thermometer was in the mid-80s Saturday afternoon, though high humidity helped the “real feel” temp reach as high as 99 degrees in some parts of the city.

Temps should stay in the 80s for the next few days, flirting with 90 degrees later in the week in the five boroughs, Tate said.

But summer thunderstorms will provide some relief.

Central Park should see a couple of heavy thunderstorms overnight and on Sunday. A flash flood alert is in effect for the Northeast due to rainfall forecast from Sunday through Tuesday.

Around New York City, the greatest risk of flooding will be from Sunday evening to early Monday, according to AccuWeather.

“I wouldn’t be surprised if we see an occasional report here or there of some standing water causing some issues or maybe some drains getting backed up but it shouldn’t be anything major,” said Tate.

Monday should be clearer, but Tate couldn’t promise there won’t be some thunder.

The southeastern United States, which experienced a blistering heat wave this week, will also get some relief, but at the expense of severe storm threats and a cold front rolling through.

The deadly heat throughout the Desert Southwest, however, will drag on, with 110-plus degree heat stretching past two weeks.

“They’re setting up for what could be one of the longest stretches of 110-degree or higher high temperatures, potentially even on record,” said Tate. “That would get them into territory where they would rival past heat waves, even by Southwest standards.”

Hot air is less dense than cold air, Tate explained, which could impact air travel in the area because it is harder to lift planes.

“Southwestern airports, notably including Phoenix Sky Harbor International Airport may have difficulties getting especially large aircraft off the ground,” he said.

And while it might feel like the Sahara in parts of the country, Florida is actually getting a piece of the African desert. A layer of Saharan dust is settling on the state, caused by strong winds that carry small sand particles from the Saharan Desert far across the Atlantic Ocean, the Miami Herald reported.

While it can make for colorful sunsets, it can be harmful to people with asthma and other respiratory issues.
