DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1630Z May 2, 2023
SMOKE: Western Canada/U.S. Rocky Mountain Region… Thin density smoke from a few wildfires and some seasonal fire activity was noted this morning in Canada stretching from southeastern British Columbia to east central Saskatchewan. The leftover smoke also extended to the south over eastern Washington, northeastern Oregon, northern and central Idaho, and roughly the western half of Montana where it likely mixed with smoke being transported to the northwest from the ongoing and widespread intense seasonal fire activity and a few wildfires burning in Mexico and Central America. The area of smoke then extended to the southeast across much of Wyoming, Colorado, and New Mexico before spreading more to the east over the South Central and Southeastern U.S. It is also possible that some dust aloft from significant dust storms in the desert regions of Asia over the past couple of weeks may be mixing in. SMOKE/AEROSOL: South Central and Southeastern U.S./Atlantic off the Southeastern U.S. Coast/Gulf of Mexico/Cuba/Mexico/Northwestern Central America/Pacific Ocean Well South of the Southern Coast of Mexico and Northwestern Central America… A very large mass of thin to moderate density smoke linked to ongoing and significant seasonal fire activity and a few wildfires in Mexico and Central America was present over portions of the south central and southeastern U.S. and extending well offshore to the east over the Atlantic Ocean. The smoke also covered most of Cuba, the Gulf of Mexico, the western Caribbean Sea, northwestern Central America, most of Mexico, and the Pacific Ocean well south of the southern coast of Mexico and Central America. The thickest smoke within this large area was seen over portions of southern and eastern Mexico, northwestern Central America, the Bay of Campeche, and the western Gulf of Mexico likely extending into the southern tip of Texas. Cloud cover though over the Bay of Campeche, southeastern Mexico including the Yucatan Peninsula, and northwestern Central America prevented a more detailed satellite based analysis of the density of the smoke in this region. UNKNOWN AEROSOL: Western and Central Canada/Area from North Central U.S. to Southeast and Middle Atlantic Region… A huge swath of thin density aerosol was seen this morning stretching from portions of western and central Canada to the southeast across the north central and central U.S. and extending farther to the southeast and east across the Mid-Atlantic region and some of the southeastern U.S. and offshore over the Atlantic. It is not known for certain, but this aerosol may be composed mostly of dust transported aloft all the way from the desert regions of Asia where significant dust storms have occurred in the past couple of weeks. Some smoke from a few wildfires burning in British Columbia, Alberta, and Saskatchewan as well as from seasonal fire activity in south central Canada and the north central and central U.S. may also be mixing in. BLOWING DUST… Northwestern Gulf of California/Far Northwestern Mexico/Western Arizona/Far Southeastern California… Remnant thin density possible blowing dust was visible this morning swirling in a counter-clockwise direction around the northwestern Gulf of California, far northwestern Mexico, western Arizona, and far southeastern California. JS THIS TEXT PRODUCT IS PRIMARILY INTENDED TO DESCRIBE SIGNIFICANT AREAS OF SMOKE ASSOCIATED WITH ACTIVE FIRES AND SMOKE WHICH HAS BECOME DETACHED FROM THE FIRES AND DRIFTED SOME DISTANCE AWAY FROM THE SOURCE FIRE, TYPICALLY OVER THE COURSE OF ONE OR MORE DAYS. AREAS OF BLOWING DUST ARE ALSO DESCRIBED.
