DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0122Z August 25, 2021
SMOKE: CONUS/near-shore Pacific/south-central Canada/Maritime Canada/Atlantic... Continued thick smoke production was observed emanating from the large wildfires across the western CONUS. Much of the smoke is moving off toward the east-northeast. Remnant smoke from this wildfire activity, along with some contribution from fires across eastern Ontario and northern Minnesota, extends at least as far east as the central North Atlantic, with the layer blanketing the Intermountain West, northern Plains, the Great Lakes, Mid Atlantic, and southeastern CONUS. Northern Canada... Thin density smoke was seen spreading to the east and across northern parts of Canada from northern British Columbia and the Northwest Territories to northern/central Ontario. The smoke may reach farther east. Smoke was most likely sourced from fires burning in Siberia a few days ago, but there could be some contribution from the western North American wildfire activity. DUST: Atlantic/Caribbean… A layer of Saharan Dust was seen across the western Atlantic moving north-northeast ahead of the remnants of Henri. Some smoke may be present as well, but the slightly more brown color noted in RGB imagery suggests mainly Dust. Another area of lighter dust was observed across the western Caribbean slowly moving westward. Some smoke may be present in this layer as well, as it may have crept southward along a front draped across Florida. A third, thicker area of Saharan Dust was seen across the eastern tropical Atlantic, moving slowly northward and westward. Eglin 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
