DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0100Z July 21, 2021
SMOKE: Alaska/Canada/U.S.... Ongoing wildfire activity across the western CONUS and western Canada was continuing to contribute to an expansive area of smoke that blanks much of North America and extends across the northern Atlantic Ocean. The thickest smoke is being emitted from the western CONUS (Dixie and Tamarack Fires in CA, the Bootleg Fire in OR, the Cedar Creek and Cub Creek 2 Fires in WA), western Canada (mainly southern BC), and central Canada (northern SK into western ON). Smoke from the fires in western Canada can be seen moving both north and north-northwestward into the Yukon and Alaska and northeastward into central Canada and eastward across Hudson Bay. Smoke from the Oregon and California fires is seen moving around the northern periphery of high pressure over the western CONUS, reaching the Great Lakes. A combination of central Canadian and western Canadian smoke is most responsible for the smoke over the rest of the central and eastern CONUS and out into the North Atlantic. A new, thick-smoke producing fire is also observed east of Bakersfield along the southeastern rim of the San Joaquin Valley. DUST: Caribbean/Atlantic... A moderate plume of Saharan dust was observed moving westward across the central and eastern Caribbean. The western edge of the dust layer was over the eastern Bahamas, eastern Cuba, Jamaica, eatern Honduras, and northeastern Nicaragua. Another thick layer of Saharan Dust was observed emerging of the African Coast, almost reaching the central Tropical Atlantic. Hosley 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. USERS ARE ENCOURAGED TO VIEW A GRAPHIC DEPICTION OF THESE AND OTHER PLUMES WHICH ARE LESS EXTENSIVE AND STILL ATTACHED TO THE SOURCE FIRE IN VARIOUS GRAPHIC FORMATS ON OUR WEB SITE: JPEG: http://www.ospo.noaa.gov/data/land/fire/currenthms.jpg GIS: ftp://satpsanone.nesdis.noaa.gov/FIRE/HMS/GIS/ KML: http://www.ospo.noaa.gov/data/land/fire/fire.kml (fire) http://www.ospo.noaa.gov/data/land/fire/smoke.kml (smoke) ANY QUESTIONS OR COMMENTS REGARDING THIS PRODUCT SHOULD BE SENT TO: SSDFireTeam@noaa.gov
