A dust plume all the way from Africa has made the trip across the Atlantic and is now creating a murky, haze in the skies along the Gulf Coast.
The Saharan Air Layer “SAL” is common across the Caribbean and Atlantic at this time of year as dust particles get suspended in the air from the Sahara Desert in Africa and are transported across the Atlantic Ocean.

SAL does tend to limit tropical development as the dusty air is also very dry which creates unfavorable conditions for hurricanes to breed.
Throughout this week the dust will likely linger along the Gulf Coast as high pressure builds in leading to more intense heat and lowering rain chances.
