DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1630Z August 25, 2020
SMOKE: Much of the CONUS, south-central Canada, and northern Mexico... A large smoke plume resulting from wildfires across the western CONUS the past couple of weeks continues to blanket a considerable portion of the CONUS, along with some portions of south-central Canada, far southeastern Canada, and northern Mexico. The thickest smoke resides in California’s Central Valley, emanating from the August Complex and SQF Complex fires, and in a ribbon extending from northern California across the Intermountain West, northern Great Plains, southern Prairie Provinces, Midwest, Great Lakes, Ohio Valley, Mid-Atlantic, Northeast CONUS, and the St. Lawrence River Valley. A southwestward extension of this layer is seen from across the Front Range, Four Corners, and northwestern Mexico. Smoke from fires in Colorado is contributing a small amount of smoke as well. Smoke from the northern Great Plains into the northeastern CONUS is moving east-southeast to east on a jet, which is what brought the lofted smoke into those areas originally. The rest of the smoke across the western half of North America will continue to move clockwise around the ridge in place over the Rockies. South-central CONUS… A couple small fires from Texas to Arkansas were observed producing moderate density smoke this morning. These smoke plumes were moving off toward the west. BLOWING DUST… Central Tropical and Subtropical Atlantic… Asurge of lofted Saharan dust was observed moving west-southwest. The leading edge was as far west as about 50W while the heart of the surge was seen extending from (10N, 35W) to (30N, 45W). 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
