DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0130Z May 24, 2021
SMOKE: Middle and Lower Mississippi Valley/Ohio Valley/Southeastern U.S./Middle Atlantic/Bahamas/Cuba/Atlantic off the Mid-Atlantic coast and Southeast/Northeastern Gulf of Mexico… A sprawling area of thin density smoke was visible late this afternoon encompassing much of the area from the Middle and Lower Mississippi Valley eastward to the Mid-Atlantic region and the Southeast. The smoke also extended offshore well out over the Atlantic and down across the Bahamas, Cuba, and the northeastern Gulf of Mexico. This smoke was likely still primarily from wildfire activity in Manitoba which has diminished in recent days. The smoke has become trapped under a very persistent large ridge of high pressure and is likely mixed with other atmospheric pollutants. Mexico/Northwestern Central America/Pacific south of Mexico/Western Texas/Eastern New Mexico/Western Oklahoma/Eastern Colorado/Western Kansas… A huge mass of thin to moderately dense smoke from the ongoing seasonal fire activity in Mexico and Central America was seen covering much of Mexico with the exception of the northwestern portion, northwestern Central America, and a sizable part of the Pacific south of the coast of southern Mexico. Moderately dense to thick smoke was present mainly across southern Mexico and off the coast of southern Mexico. A swath of thinner density smoke from this fire activity also spread to the north over western Texas, eastern New Mexico, far western Oklahoma, eastern Colorado, and western Kansas. The smoke may also extend farther to the north, but that was not certain in satellite imagery. Unknown Aerosol… North Central U.S… An unknown thin density aerosol was seen later in the afternoon over the central and eastern portions of the Dakotas and Minnesota. This aerosol may be composed in part by at least some smoke possibly linked to the northward transport of smoke up over the Plains from the ongoing seasonal fire in Mexico though that is not certain. Dust: Colorado… A few patches of thin density blowing dust were visible moving to the northeast this afternoon over south central and east central Colorado. JS Earlier This Morning... DUST: Central Canada…. An area of unknown aerosol, possibly blowing dust from portions of the southwest United States mixed with an area of light smoke, was extending from northern Manitoba west through central Saskatchewan into central Alberta. Caribbean Sea…. An area of Saharan Dust was seen over portions of the southeastern Caribbean Sea and extending west into portions of the western Caribbean Sea.
