THROUGH 2330Z July 21, 2025
SMOKE: Alaska/Canada/Atlantic Ocean/Central and Northeast United States/... Wildfires continued to burn in eastern Alaska/Yukon, the Northwest Territories, northern British Columbia, and central Canada, with widespread smoke observed across most of Canada and extending east towards the Atlantic and south over the Great Lakes region and northeastern United States. Higher density smoke was concentrated in much of central Canada, specifically located over Alberta, central Saskatchewan, northern Manitoba, and central Ontario. Western U.S... Wildfires were observed across the western U.S., from Washington State to New Mexico. Smoke originating from the wildfire in northern California was seen drifting eastward. Smoke from the wildfire in northern Arizona was seen drifting towards the northeast. Cloud cover obscured further smoke analysis in this region. DUST: Atlantic Ocean... Saharan dust was observed blowing westward across the Atlantic Ocean, drifting towards the Caribbean. Libby 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 Smoke data: https://satepsanone.nesdis.noaa.gov/pub/FIRE/web/HMS/Smoke_Polygons Fire data: https://satepsanone.nesdis.noaa.gov/pub/FIRE/web/HMS/Fire_Points ANY QUESTIONS OR COMMENTS REGARDING THIS PRODUCT SHOULD BE SENT TO: SSDFireTeam@noaa.gov
