THROUGH 1440Z July 21, 2025
SMOKE: Alaska/Canada/Atlantic Ocean/Central and Northeast United States/... Wildfires continued to burn in eastern Alaska/Yukon, and central Canada, with widespread smoke observed across Alaska, most of Canada and extending east towards the Atlantic, north into the Arctic, and south over the Great Lakes region and northeastern United States. Higher density smoke was concentrated in much of central Canada, specifically located over central Saskatchewan, northern Manitoba, and central Ontario. Western U.S... More than a dozen 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. 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. Ferrante 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
