DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0100Z July 25, 2021
SMOKE: Western United States and Canada… Dense smoke from wildfires in northern California and southwestern Oregon, in particular the Dixie and Bootleg fires, was observed moving north and then eastward across much of Oregon, northern Nevada, and southern Idaho. In addition, numerous wildfires across Washington, northern Idaho, western Montana, and southern British Columbia were also producing smaller but still dense individual smoke plumes extending eastward and generally confined to those regions. However, an area of combined remnant smoke from these fires, of moderate to high density, extended eastward across southern Canada and the northern United States at least as far as the Great Lakes before becoming obscured by widespread cloud cover. Manitoba and Ontario… Numerous fires from eastern Saskatchewan to northern Ontario were producing large plumes of dense smoke extending across much of Ontario and northeastward over Hudson Bay, as well as Lake Superior and portions of Michigan’s Upper Peninsula, where the smoke merges with the remnant smoke from the aforementioned western fires. Arctic Canada and Alaska… Fires in northern Yukon and the Northwest Territories were producing localized plumes of dense smoke which merged with a large area of remnant smoke extending westward across northern Alaska. Elsewhere… Areas of remnant smoke of up to moderate density from the above wildfire activity were observed across much of the eastern United States and the northwestern Atlantic Ocean as far east as Newfoundland. DUST: Caribbean Sea, Central and Western Atlantic Ocean... An area of Saharan dust extended from the central tropical Atlantic Ocean northwestward to Bermuda and the western Atlantic, with an additional area of dust observed in the eastern Caribbean Sea south of Hispaniola and Puerto Rico. MTC 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
