The Saharan dust storm is expected to arrive in San Antonio next week, bringing with it hazy skies and breathing troubles, particularly for people with respiratory illnesses such as asthma and COPD.

The dust storm can cause asthma attacks and heart disease symptoms, and increase the risk of respiratory infections, especially for individuals with pre-existing respiratory conditions.

The Saharan dust storm can also exacerbate pre-existing respiratory conditions, such as asthma, and cause skin problems and other health issues.

People with heart or lung disease should follow their doctor's advice and avoid prolonged exposure to high particle pollution.

The Saharan dust storm can pose significant health risks to citizens of San Antonio, particularly those with pre-existing respiratory conditions, and can also cause minor allergy-like symptoms in some individuals.

To minimize health risks, citizens of San Antonio can take precautions such as staying indoors during high dust levels, avoiding outdoor activity and exercise, and keeping windows and doors closed.

Air purifiers and air conditioners can also help reduce exposure to particulate matter indoors.

Carpooling and telecommuting can help minimize outdoor particulate levels, and stabilizing loose soils can reduce particulate matter.

Wearing masks, especially particle-retaining masks, can help reduce health risks, particularly for people with lung diseases.

The Saharan dust storm can last for several weeks, and residents of affected areas should be warned to take precautions to safeguard their health.

Dust storms can trigger allergy symptoms in people with asthma, and can also irritate airways and exacerbate allergies.

The Saharan dust storm can transport harmful bacteria and fungi, and can also introduce microbes into local environments, affecting human health.

Climate change can alter the frequency and intensity of dust storms, and can also affect the severity of the Saharan dust storm.

The Saharan dust storm can disrupt local ecosystems and stress coral reefs, and can also carry pollutants and pathogens that can affect air quality.

To prepare for the Saharan dust storm, people can take precautions such as reducing trips, taking public transportation, and slowing down on dirt roads.

The Saharan dust storm can affect the power grid in San Antonio, TX, by reducing solar energy production and increasing energy demand, which may lead to a strain on the grid.

ERCOT, the operator of the Texas power grid, has triggered emergency operations due to high demand in the past, which may be a concern during a Saharan dust storm.

Texas has broken power demand records multiple times in the summer, and the Saharan dust storm could lead to increased energy demand and potentially cause the power grid to fail.

The power grid in Texas has limited connections to larger US grids, which may make it more vulnerable to failures during periods of high demand.

To mitigate the effects of the Saharan dust storm, it is essential to conserve energy and reduce strain on the power grid.

ERCOT calculates demand reduction to keep the grid from failing, which may involve asking customers to conserve energy.

The Texas power grid has handled increased demand in the past with the help of green energy, which may be an essential factor in mitigating the effects of the Saharan dust storm.

Green energy generated nearly 40 percent of Texas' electricity, and natural gas generated nearly 45 percent, which may help to reduce the strain on the power grid during a Saharan dust storm.

The Saharan dust storm can also impact traffic in San Antonio, TX, by reducing visibility and causing hazardous driving conditions.

Dust storms can reduce visibility to less than one mile, leading to dangerous driving conditions and increased accident risk.

Strong winds exceeding 50 mph can cause hazardous travel conditions and increase accident risk during a dust storm.

Reduced visibility due to blowing dust requires drivers to exercise caution and take necessary precautions to avoid accidents.

The Saharan dust storm can fertilize remote ecosystems, but it can also disrupt local environments and harm coral reefs.

Climate change alters dust storm behavior and frequency, which can impact the severity and frequency of dust storms in the Americas.

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.

Title:

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.

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.

Dust storm from Sahara to hit Türkiye

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.

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.

How does Saharan dust affect immediate weather?

What are the negative health effects of Saharan dust?

The Saharan dust storm can transport harmful bacteria and fungi, and can also introduce microbes into local environments, affecting human health.

Title:

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.

The state’s power grid operator triggered its emergency operations on Wednesday evening, allowing it to call on all available power generation to stay ahead of demand — and bringing it closer than it's been all summer to a worst-case scenario of ordering rotating power outages.

The Electric Reliability Council of Texas got through the tight stretch without having to call for power cuts to customers in order to prevent the grid from being severely damaged. ERCOT triggered its second of three levels of emergency operations at 7:25 p.m. It lifted emergency conditions 77 minutes later, when plenty of surplus power was again flowing to the grid to meet demand.

Intense heat this summer has tested grid operators, repeatedly forcing them to turn to backup tools to keep operations running smoothly. ERCOT asked Texans to conserve energy 10 times this summer because of the high demand for power. On Wednesday, wind power was also forecast to be low.

The afternoon and evening hours tend to be tightest as people return home from work and crank down their thermostats. Solar power generation, which has grown significantly in recent years in Texas, also dwindles as the sun sets.

Grid operators asked power users to cut back their electricity consumption between 6 p.m. and 9 p.m. Wednesday. Power customers can conserve by turning up thermostats a few degrees and refraining from using large appliances such as washing machines and clothes dryers during this period.

ERCOT said it was calling on large power users to reduce their consumption and asking other major U.S. grids to provide what help they could. The ERCOT grid, which serves most of the state, has limited connections to the larger grids that serve the rest of the nation.

The state has broken its power demand record 10 times so far this summer because of economic and population growth and the punishing heat.

Rolling outages remain a rare last resort. ERCOT has not called for them since the devastating February 2021 winter storm, when power was cut to millions of homes over days while extremely cold weather persisted. More than 200 people died.

During that storm, the initial plan to cut power for short periods was abandoned when numerous power generators suddenly failed amid days of subfreezing temperatures, requiring the widespread shutdown of power for days.

If ERCOT had called for electricity cuts again on Wednesday, the location and duration of power outages would have been controlled by individual electric utilities. For example, CPS Energy President and CEO Rudy Garza in San Antonio said last month when conditions looked tight that outages would last between 10 and 15 minutes for their customers.

Representatives for other utilities said the duration of power outages and whether they would rotate would depend on what they hear from ERCOT, which calculates how much demand must be reduced to keep the grid from failing.

People with generators should not use them indoors because they emit deadly carbon monoxide.

How can the authorities prepare for a Saharan dust storm?

What areas of the Americas have been affected by Saharan dust storms?

Texas has broken power demand records multiple times in the summer, and the Saharan dust storm could lead to increased energy demand and potentially cause the power grid to fail.

What areas of the Americas have been affected by Saharan dust storms?

What areas of the US have been affected by Saharan dust storms?

The power grid in Texas has limited connections to larger US grids, which may make it more vulnerable to failures during periods of high demand.

To mitigate the effects of the Saharan dust storm, it is essential to conserve energy and reduce strain on the power grid.

How can the authorities prepare for a Saharan dust storm?

ERCOT calculates demand reduction to keep the grid from failing, which may involve asking customers to conserve energy.

The Texas power grid has handled increased demand in the past with the help of green energy, which may be an essential factor in mitigating the effects of the Saharan dust storm.

Heat waves have posed deadly threats across the U.S. as people battle adverse health effects from high temperatures.

In Texas, where temperatures have exceeded triple digits for 10 consecutive days, residents are using immense amounts of energy to run air conditioners. While companies have reassured residents the power grid is capable of handling the demand, the weather has sparked conversations about whether the state needs to diversify its energy resources.

Texas has been especially susceptible to the high heat this summer, with some parts of the state expected to see triple-digit temperatures for at least the next 10 days, according to forecasters. A power grid that has been unreliable in past extreme weather events has residents questioning if it can handle the increased demand. So far, it has.

Texas has battled high heat for weeks, with several cities breaking records. Del Rio broke its all-time high of 113 degrees on June 21, when the temperature reached 115. San Angelo broke a record on June 20 by 3 degrees when the temperature hit 114. San Angelo then tied the new record the next day, according to a report by The Weather Channel.

AccuWeather meteorologist Nicole LoBiondo told Newsweek that Texas temperatures are "very hot for this time of year," and that they will remain hot into next week.

Texas' power grid failed in February 2021, when a severe winter storm and frigid temperatures stressed it to the point of failure and thousands lost power. But so far the grid has maintained its performance with the help of green energy.

On Monday, data from the Electric Reliability Council of Texas (ERCOT) showed that power from wind and solar energy sources generated nearly 40 percent of the state's electricity. Natural gas remained the largest generator of power in Texas, accounting for nearly 45 percent while coal sources generated more than 10 percent.

ERCOT provides power for 26 million customers in Texas, roughly 90 percent of the state's load. Despite the assistance from green energy sources, ERCOT issued a weather watch on Friday through Tuesday because of the high temperatures heightening electrical demand.

A weather watch is implemented when grid conditions are normal but there is a forecast that likely will cause high demand. It could be followed by a voluntary conservation notice.

"Grid conditions are expected to be normal during a Weather Watch. ERCOT continues to monitor conditions closely and will deploy all available tools to manage the grid and will continue our reliability-first approach to operations," it said.

A spokesperson from ERCOT told Newsweek that a weather watch is not a call for energy conservation.

"ERCOT will continue to operate the grid conservatively, bringing generating resources online early to mitigate sudden changes in generation or demand," the spokesperson said.

According to the announcement, ERCOT set an unofficial peak demand record of 81,406 megawatts last Thursday, but the most updated supply-demand chart shows that the grid continues to meet the increased demand.

How can the authorities prepare for a Saharan dust storm?

Green energy generated nearly 40 percent of Texas' electricity, and natural gas generated nearly 45 percent, which may help to reduce the strain on the power grid during a Saharan dust storm.

The Saharan dust storm can also impact traffic in San Antonio, TX, by reducing visibility and causing hazardous driving conditions.

sources and danger.
|
At the beginning of this year's spring season, the incidence of dust storms increased significantly.
Their frequency varies from year to year, but generally increases in the transitional periods between seasons, especially spring and autumn, for many reasons, some natural and others of a human nature, that is, by man.
Dust storms are fast winds that transport dust and plankton, causing a lack of visibility at short distances.
Despite the great controversy over the causes of dust or dust storms and the fact that the camel bears full responsibility for their occurrence, as stated in one of the videos circulated on social media, the reasons are not limited to the poor camel alone, even if it is one of the reasons!
The causes of dust storms are many, including: (1) Desertification as a result of drought resulting from low rainfall.
(2) Desertification due to human activities associated with overgrazing as a result of increasing numbers of camels and sheep on pasture capacity.
(3) Extensive agricultural activities, especially ploughing the land and leaving it exposed for long periods.
(4) Soil movement as a result of development and military actions and absurd car tracks in deserts that led to the breaking and dismantling of the soil and the destruction of vegetation cover.
(5) The reduction of the surface groundwater table, which led to the drying of the soil and thus the impact on the vegetation cover.
Globally, sub-Saharan Africa is the main contributor to Earth ’ s dust storms, which travel to the Americas via the Atlantic Ocean via tropical east winds.
But the Fertile Crescent has also become a source of dust, due to the halving of agricultural production as a result of climate change.
Iraq is one of the sources of dust storms as a result of the decline of the level of rivers, which led to the drought of the marshes and lakes in Iraq and Iran, and add to the list of sources open deserts of the Kingdom, which suffer environmental degradation as a result of human tampering of unfair grazing and wood and the like.
Dust storms are one of the factors responsible for increased allergic reactions, asthma attacks and chronic breathing problems, as well as blood vessels and heart disease.
Dust storms are also carriers of microorganisms, including bacteria, fungi, germs and viruses that cause certain diseases.
Besides, dust storms have economic effects, they adversely affect agricultural production by transporting agricultural pests, reducing photosynthetic activity, destroying crops, as well as affecting infrastructure, by reducing visibility, disrupting energy and air and road transport systems, burying railways, as well as contributing to the deterioration of the performance of solar panels, as well as damaging residential property.
There is no doubt that dust storms and their increased frequency are a warning sign that requires a rapid response through a review of environmental regulations, the need to raise the environmental awareness of the population, the organization of grazing seasons based on the identification of the pastoral capacity of each region, as well as innovative solutions to mitigate desertification that benefit from tremendous technical progress.
Finally, it follows from the above that the problem is not country-specific, but a regional problem that requires concerted efforts.
The Green Middle East initiative by Prince Mohammed bin Salman is designed to design innovative solutions to address climate change and promote environmental sustainability through a number of projects, including: planting 50 billion trees across the Middle East region and reclaiming 200 million hectares of degraded land through afforestation, which contributes to a 2.5 per cent reduction in global carbon emissions.

Increasing clouds & tropical moisture

Best chance of rain/showers for the next 7-days arrives Saturday
Posted at 5:07 AM, Aug 05, 2022
and last updated 2022-08-05 07:23:27-04

CORPUS CHRISTI, Texas — We’ll have a welcome shift to our hot and dry weather pattern coming in the next 24-48 hours. That shift includes more tropical moisture moving into South Texas from the Gulf of Mexico that will result in a few isolated to scattered showers and storms across the area.

This is going to be another situation where many of us will only be teased by rainfall activity and is going to leave us wanting a whole lot more than what’s on the way.

A weak easterly flow off the Gulf will give way to a weak upper-level disturbance that will fire off showers and storms near the coast. So, that’s where the best chance for some rain will occur late tonight, early Saturday and through the first part of the day. As the afternoon seabreeze gets going, some of that activity will translate inland, but start to weaken rapidly.

Rainfall amounts will be best near the coast where a quarter to half inch of rain will be possible. There will be some spotty locations that could receive some locally higher amounts. For everyone else, expect nothing to just a trace of rain to perhaps a couple of hundredths.

After Saturday, upper-level high pressure will begin to build back into the area and we’ll be back into our typical August weather pattern which includes very hot temperatures, humid conditions and only a stray shot at an afternoon seabreeze shower that teases many of us each day. For those who happen to get in on any shower activity over the next 7-days, consider yourself very lucky.

Saharan dust will wash out of our skies today, but there’s still plenty more off in the tropical Atlantic and is keeping things quiet. NOAA and Colorado State University updated their forecast number of storms for the 2022 season and though they lowered their numbers slightly, they’re still expecting a busy peak of the season which is around September 10th.

Today: Partly to mainly cloudy, still hot, humid and breezy…High: 95…Wind: ESE 15-20 MPH…Heat Index: 104-109.

Tonight: More clouds moving in with increasing showers and storms moving in from the Gulf…Low: 74…Wind: SSE 4-8 MPH.

Saturday: Our best chance of rain over the next 7-days. Mainly cloudy with isolated to scattered showers and storms. Best chance near the coast. Rainfall amounts will not be impressive. Few locations could pick up a quarter to half an inch quickly. Only a few hundredths to a couple tenths on average…High: 93…Wind: SE 15-20 MPH…Heat Index: 100-105.

Sunday: Partly cloudy skies, hot, humid and breezy with a few stray seabreeze afternoon showers…High: 94…Wind: ESE 10-20 MPH.

Monday: Partly cloudy skies and getting hotter with still plenty of humidity and a good breeze. A passing stray seabreeze shower is possible…High: 95…Wind: ESE 10-20 MPH…Heat Index: 105-110.

Tuesday: Partly cloudy, breezy, hot and humid with a stray shower possible…High: 95…Wind: ESE 10-20 MPH…Heat Index: 105-110.

Wednesday: Still holding on to a few clouds, very hot, muggy and breezy with a stray shower…High: 96…Wind: ESE 10-20 MPH…Heat Index: 105-110.

Have a great weekend and hopefully we can make use of our dusty umbrellas on Saturday!

The Saharan dust is expected to wash out by the end of the day, with rainfall amounts of a quarter to half inch near the coast.

The best chance of rain is on Saturday, with a high temperature of 93 and wind coming from the SE at 15-20 MPH.

The heat index on Saturday is expected to be 100-105, with a chance of stray shot at an afternoon seabreeze shower after Saturday.

The Saharan dust will arrive in San Antonio next week, peaking in late June through mid-August, with heavy dust staying over the Gulf Coast on Monday.

What areas of the Americas have been affected by Saharan dust storms?

What areas of the US have been affected by Saharan dust storms?

Moderate dust will move into San Antonio by Tuesday afternoon, ramping up by Wednesday and reaching Dallas, with dust levels rising on Thursday and affecting air quality.

Author: Lauren Kreidler
Published: Updated:

As we kick off the weekend, we can expect hot and hazy skies due to some Saharan dust lingering around.

Temperatures will stay slightly above average, reaching the low to mid-90s by afternoon.

“Clouds and typical summertime afternoon scattered storms will help to keep us below that Heat Advisory threshold, though it is still going to feel hot outside,” added The Weather Authority Meteorologist Lauren Kreidler.

It’s not looking bad for boaters. Winds are out of the southeast and west, around 5 to 10 knots.

Sunday’s weather will be similar, though a few degrees warmer in some spots. Highs will reach the low to mid-90s yet again, with more afternoon scattered storms.

All is quiet in the tropics. No areas are expected to develop in the next 7 days.

Scattered storms will occur in the afternoon, with the heat advisory threshold being avoided, and highs reaching low to mid-90s again.

The temperature will fall to the 50s during the storm, with wind speeds reaching 30-40 miles per hour, and a chance of rain showers and thunderstorms on Saturday.

There's even some talk of hail.

After a few days of temperatures uncharacteristic for this time of year, San Antonio will see its share of showers and storms brought on by a strong cold front. The National Weather Service says San Antonio will face wet and windy conditions this weekend, according to a report distributed Friday.

The cold front is expected to move through the area Saturday, bringing a chance for rain showers and thunderstorms throughout the day.

San Antonio-area residents should be prepared for colder temperatures and gusty winds later Saturday as these conditions are likely to follow the cold front, NWS says. Temperatures are set to fall into the 50s while wind speeds may reach between 30 and 40 miles per hour.

Residents in the Hill Country as well as drivers along and east of I-35 and I-37 should especially be aware of weather conditions since heavy rainfall is more likely in these areas. Though few, storms here are expected to be strong and could even be severe. Winds may be damaging while small hail is also a potential threat, one that’s driven by the warmer temperatures uncharacteristic for this time of year. NWS says minor flooding is possible in these areas.

At this time, Sunday’s forecast for San Antonio also includes cool conditions as well as a chance of rain that night.

Gusty winds are expected later on Saturday, with heavy rainfall likely in Hill Country areas, and storms possibly being severe with damaging winds.

Minor flooding is possible in some areas, with the rain chance continuing on Sunday night, and a cold front moving through on Saturday.

Temperatures in San Antonio will fall into the 60s on Thursday afternoon, settling into the 50s by Thursday night, with wind gusts up to 25-30 mph expected by late Thursday.

Content: Thursday’s cold front brings cooler air, rain chances into South Central Texas

Not as cold as the front before Halloween, but cool enough to break out the sweaters this weekend!

After a warmer than average first half of the week, a cold front will push through South Central Texas on Thursday, sending rain chances and cooler air back into the forecast.

Here’s the latest:

Key Points

  • A cold front arrives in South Central Texas on Thursday, pushing through the Hill Country in the morning, then moving into the San Antonio area around midday
  • After reaching the mid-70s around lunchtime, temperatures will fall into the 60s in the afternoon followed by the 50s Thursday night. Wind gusts up to 25-30 mph will also kick on after the front passes by
  • Rain chances increase along and behind the front, with scattered-to-widespread activity expected by late Thursday afternoon, evening and overnight
  • Lingering showers will be possible for the Friday morning drive before tapering off through the remainder of the day. Cloud cover is slated to hold afternoon temperatures to near 60 degrees
  • A cooler forecast returns for the weekend with highs in the low 60s and lows in the 50s. Most will catch a break from the rain Saturday before another round tries to work in Sunday and into Monday

Cold Front Arrival Times Thursday

  • Hill Country: 8 a.m. - 11 a.m.
  • San Antonio Area: 11 a.m. - 1 p.m.
  • Coastal Plains: 1 p.m. - 4 p.m.

The cold front will start to push through the Hill Country around or just after the morning commute. As it continues to slide southbound, the boundary will then move through the San Antonio area around lunchtime and push through the Coastal Plains through the early afternoon.

Temperatures & Rain Chances

After starting off in the muggy upper 60s Thursday morning with some patchy drizzle, temperatures will manage to climb into the mid-70s by midday in San Antonio. After the front passes by, thermometers will fall through the 60s Thursday afternoon and eventually settle into the 50s by Thursday night. Expect gusty north winds to also kick up as the front passes by, with wind gusts upwards of 25-30 mph expected by late Thursday afternoon and evening.

Rain chances will also increase as the front passes through the area, and even more so behind it. A broken line of rain is forecasted to accompany the boundary’s arrival, followed by scattered-to-widespread rain into the Thursday afternoon, evening, and overnight timeframe. Scattered, lingering showers are expected around the Friday morning drive, but the remaining activity should taper off through the remainder of the day with cloud cover holding afternoon temperatures to about 60 degrees and wind gusts up to 25 mph.

Weekend Forecast

Most should catch a break from the rain Friday night and Saturday, minus an isolated shower or two. While not as cold as the front that arrived in time for Halloween last week, sweater weather returns this weekend with lows in the 50s followed by highs in the low 60s Saturday and Sunday.

Another round of rain will try to work into parts of South Central Texas on Sunday and into Monday. Still some details to fine-tune with this second round, but it’s possible that up to 1-2 inches of rain could fall in spots by the time all is said and done, so check back for updates in the coming days!

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.

Content: Older Barbadians being diagnosed with asthma Loop Barbados

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.
