DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1430Z September 22, 2025
SMOKE: Northwest Territories/Central Canada/Southeastern United States… Wildfires persisted throughout Canada in British Columbia, Alberta, Saskatchewan, and southern Northwest Territories. Moderate-to-heavy density smoke from fires in the southern Northwest Territories was observed drifting east and north into Nunavut. A wildfire in northeastern Alberta also produced moderate-to-heavy smoke that moved north into the Northwest Territories, while fires in central Alberta generated light smoke spreading eastward into Saskatchewan. These fires collectively produced additional areas of light smoke that spread across Nunavut, Saskatchewan, and Manitoba. The light smoke also extended south into Montana, North Dakota, and South Dakota, before moving east. The light smoke reached the southeastern region of the United States and the northern Gulf of America. Washington State… Fires continued across Washington State, producing moderate-to-heavy smoke plumes which moved southward and then eastward from Chelan County and Kittitas County. Light smoke from these fires appeared to have extended northeastward over northern Montana and southern Saskatchewan, merging with the broader smoke that had already spread across the United States and into Canada. Hernandez 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
