Saharan dust will hit Mississippi, Gulf Coast soon. What to know about weather, air quality
It's back. The first rounds of Saharan dust are set to sweep over Mississippi and the Gulf Coast this weekend and in the first week of June. They'll keep coming all summer. Also known as the Saharan Air Layer, the annual weather phenomenon can help dampen hurricanes. It brings stellar sunsets and sunrises to the U.S. and can affect air quality. The initial band will roll over parts of South and Central America, Cuba, the Bahamas, and Florida. A second, massive plume is set to spread over Mississippi, Louisiana, Texas and Alabama around the middle of next week. Here's what the Mississippi weather forecast calls for, what to know ahead of the dust blowing over the Magnolia State. Just like the name sounds like, dust and dirt from the Sahara Desert in Africa. According to the National Oceanic and Atmospheric Administration, the dry, dusty air forms over the arid region from spring through autumn. Tradewinds can catch the dust, pushing a 2-2.5 mile thick layer in the atmosphere about a mile above the ground or ocean. According to NOAA, it's common for Saharan dust to cross the Atlantic to the Western hemisphere. In the U.S., bands will hit about every three to five days. It usually starts around June, and the strongest activity is from June to the middle of August. Florida is often affected by the airborne dust, according to NOAA, but it can reach as far west at Texas. The plumes pushed across the ocean can be massive, some are as large as the lower 48 states. More: Hurricane Hunters aim high, fly low. What to know about this MS team ahead of hurricane season Yes. Saharan dust can affect air quality and trigger coughing and sinus issues for some people, especially if the coverage is thick. If you're concerned about breathing in the particles, use a mask outside and an air purifier with a filter indoors. People with asthma or other health issues affected by air quality might want to stay inside as much as possible when the dust is heavy in your area. The U.S. Centers for Disease Control and Prevention defines the weather phenomenon as a form of particulate pollution. It's made of sand and minerals, but it's not the same kind of dust as the household variety with dust mites. According to information from Baptist Health System, the respiratory issues caused by the dust can mimic a COVID-19 infection. Coughing and chest tightness with no fever might be an allergic reaction or your body responding to an irritant. But if your temperature climbs or you lose sense of taste, consider COVID. The Instituto Espaillat Cabral, an ophthalmology center in the Dominican Republic, recommends wearing protective eyewear and keeping your eyes hydrated to keep the dust from irritating your eyes. If you get debris in your eye, avoid rubbing it. Yes! Multiple studies have looked at the contents of debris spread in the U.S. and Europe. Dust from the Sahara Desert can carry bacteria and fungi. Fact check: Magnetic residue in video is sand from Sahara, not evidence of 'chemtrails' Sort of. It can suppress the energy needed for hurricanes to form and intensify. It's more like starving a storm than making one stop in its tracks automatically. Large amounts of dust can keep the surface of the ocean slightly cooler, which can help prevent storms from growing or forming. According to the National Weather Service, the lower humidity and warm, dry air can also weaken an existing storm with downdrafts or throw off the heat signature of a cyclone.

Manchester 'dust devil': Plans in place to prevent repeat of phenomenon
"Appropriate measures" will be put in place to prevent a repeat of a dramatic "dust devil" that startled onlookers in Manchester over the swirling 30ft (10m) column of dust and debris was pictured beating a path across Great Ancoats Street in the city centre on Saturday afternoon. Similar in appearance to a mini-tornado, the phenomenon was caused by contrasts in temperature causing air to rotate. Manchester City Council said the dust devil originated from the Central Retail Park building site, a vacant swathe of open land which is being redeveloped into a civil service office complex. The authority said: "The meteorological conditions required to create a so-called dust devil are uncommon in urban areas and so it's rare that a site is affected in the way we saw over the weekend."However, dust control is a consideration for any development, and we'll ensure the developer takes appropriate measures to manage the site throughout the construction period." 'Most amazing thing' One eyewitness said he "froze" when she saw the column of dust spiralling towards him. Violinist Adam Riding, 30, said: "It was the most amazing thing. "I've never seen anything like that, and to witness it in the city on really not a very windy day. "It was like this wind tunnel between buildings had created this mini-vortex. It was bizarre."Met Office meteorologist Alan Goodman said dust devils were a "rare occurrence" in the said: "The ground was very, very warm. When you get this very warm air near the ground it will rise."And then if you just get it right, the air starts to rush in from the sides and you get this sort of rotation motion."The Government Property Agency, which is redeveloping the Central Retail Park site, said the dust devil was the result of "exceptional meteorological conditions".It added: "In response to this, the contractors currently managing the site have taken the additional steps of bringing in a road sweeper and a towable water bowser to reduce the likelihood of dust being blown from this plot if unusual weather patterns continue."

Manchester: What caused 'dust devil' that hit city centre?
An expert has explained why people saw what they thought was a "mini-tornado" passing through a city centre. A swirling 30ft (10m) column of dirt rose into the air around Great Ancoats Street in Manchester on Saturday. A meteorologist told the BBC the phenomenon was a rare "dust devil". Alan Goodman, from the Met Office, said there had been "ideal combination of conditions" for the weather event. Mr Goodman said: "It's a rare occurrence in the UK, never mind in the middle of a UK city." Mr Goodman said the dust devil had formed over an "open patch of ground with a lot of dust", following months of unusually dry weather. He added: "The ground was very, very warm. When you get this very warm air near the ground it will rise. "And then if you just get it right, the air starts to rush in from the sides and you get this sort of rotation motion."There was obviously enough dust from this patch of open ground and away it went."Mr Goodman reassured residents that, although it had the appearance of a mini-tornado, a dust devil was "nowhere near as dangerous or destructive". "But impressive nonetheless, and probably a first for Manchester," he added. Listen to the best of BBC Radio Manchester on Sounds and follow BBC Manchester on Facebook, X, and Instagram.
