DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1700Z June 18, 2021
SMOKE: Much of the Lower 48/Southeastern Canada/Northern Mexico/Extreme western Atlantic/Northwestern Gulf of Mexico/Eastern Pacific to the west of California and Mexico… The enormous area of thin density smoke continued to be visible this morning covering much of the lower 48 in the U.S. with the exception of the area stretching from Washington, Oregon, and far northern California eastward to the western Great Lakes region. Florida and a portion of the Gulf Coast may also be smoke free though cloud cover in that region prevented smoke detection in satellite imagery. The smoke also was present over southern and eastern Quebec, the far western Atlantic off the U.S. east coast, the northwestern Gulf of Mexico, northern and western Mexico, and the eastern Pacific off the coast of California and western Mexico. Within the thinner density smoke was a sizable batch of moderately dense smoke over western and northern Mexico, the Gulf of California, Baja, and virtually all of the Southwestern and South Central U.S. from southern California and Nevada eastward to the Middle and Lower Mississippi Valley. A rather narrow curved stripe of moderately dense to perhaps thicker smoke was seen within this region from eastern Texas over northern Louisiana, and the central parts of Mississippi and Alabama. This stripe of smoke was likely being concentrated aloft by the presence of a possible developing tropical system in the north central Gulf of Mexico. Thicker smoke was also visible closer to some of the wildfires in western Mexico and in Arizona and western New Mexico. The majority of this vast coverage of smoke was due to wildfires burning especially in Arizona, New Mexico, Utah, and southern Montana as well as western Mexico. South Central Canada/Lake Superior… Some thin density smoke was visible spreading to the east around a thicker cloud deck over southern and eastern Ontario, western Quebec, and a portion of Lake Superior. This smoke was from several wildfires burning in western Ontario. Alaska/Northwestern Canada… Several wildfires in central and east central Alaska and the central part of the Yukon in northwestern Canada were responsible for a west to east elongated swath of mainly thin density smoke which was seen extending from northeastern Alaska over the northern Yukon and much of the Northwest Territories in northwestern Canada. DUST: Caribbean region/Bahamas/Southern Florida… The western portion of rather thin Saharan dust was seen this morning over Cuba, the western Caribbean, and a portion of the eastern Gulf of Mexico. The dust may also be present a bit farther to the north over the Bahamas and Florida though cloud cover there prevented detection in satellite imagery. Farther to the east, more Saharan dust was located over Puerto Rico and the islands to the east and southeast of there and extended well to the east over the subtropical and tropical portions of the Atlantic to the west coast of Africa.
