Biggest Saharan Dust Cloud In Decades Hits The US

"And if you look at the satellite you can actually see how the clouds have just eroded where there's the presence of dust in the atmosphere".

A massive dust plume from the Sahara desert is already making its way through the southern part of the USA and will envelop cities between Texas and NY by Sunday.

Weather experts were reported as saying that the dust could cover the Yucatán Peninsula and western Gulf of Mexico, with even parts of the Mississippi Valley, Tennessee Valley, and the south-east U.S. expected to encounter a dusty shroud over this weekend.

Fox 35 Weather reported the massive dust storm brought its heaviest concentration over Puerto Rico and other parts of the Caribbean, leading to hazardous air quality conditions and a reduction in visibility in some areas - though it is not now expected to cause major reductions to Florida's air quality. The American Asthma and Allergy Foundation recommended vulnerable people to take precautions and try to limit their time outdoors, where the air quality will be poor.

The dust plume, which has been traversing thousands of feet above the Atlantic ocean, arrived in central America earlier this week, covering the majority of the central and western Gulf of Mexico with haze engulfing the region.

The Saharan Air Layer typically fires up its activity in mid-June, often bringing with it a bunch of desert sand and peaks over the course of the summer.

It can also irritate sinuses, McClatchy News reported. "This particular one is impressive in its size and the amount of dry, dusty air it contains", Wilkinson said. It can also cause sinus problems and itchy eyes, nose and throat for people who are sensitive to those symptoms.

The dry air mass that carries the dust can suppress tropical storm and hurricane formation and can enhance and illuminate sunrises and sunsets, meteorologists said.

As far as sunsets go, they're pretty breathtaking.

A Saharan air layer happens when dust from the Sahara desert occupies a 2 to 2.5-mile thick layer of the atmosphere with the base starting about one mile above the surface.

Dust clouds from the Sahara aren't rare.

This year's outbreak is considered especially unique due to its thickness. Scientists are saying the dust storms over Senegal the last few weeks were the worst in 50 years. She has an MSt from the University of Cambridge and lives in Kansas City.
