DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1430Z September 26, 2025
SMOKE: Northwest Territories/Central Canada... Wildfires continued across central Canada this morning, with the heaviest smoke originating from the fires in the southern Northwest Territories and central Alberta. Moderate smoke from these wildfires moved eastward across the Northwest Territories and then curved south but was obscured by heavy cloud cover. The smoke appeared to spread over Manitoba, western Ontario, and northern Minnesota, thinning to light smoke as it drifted across southeastern Saskatchewan, Ontario, and the Midwestern United States. Additional light smoke spread southward across the central United States into the northwestern Gulf of America. Western United States... Wildfires continued in Washington, Idaho, Montana, and Oregon, with the heaviest smoke being produced by the fires in central Washington. Moderate-to-heavy smoke from these wildfires drifted eastward across Washington, northern Idaho, and Montana, merging with smoke from the Canadian fires. A large fire in southwestern Oregon was producing light-to-moderate smoke moving south toward California and the Pacific Coast. GL 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
