DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1500Z September 30, 2025
SMOKE: Northwest Territories/Central Canada/Southeastern CONUS… Wildfire activity continues to be analyzed across the southern Northwest Territories, northern Alberta, west-central Saskatchewan, and southern Manitoba. Some cloud cover was present across much of the Pacific Northwest and Canada, which obscured some of the smoke produced from the fires. However, moderate smoke produced from the fires in west-central Saskatchewan remained visible, as the smoke moved northeast towards the southern Northwest Territories. Light smoke from the fires in northern Alberta and southern Northwest Territories produced light smoke, which moved east towards southern Manitoba and Ontario and southeast towards the Atlantic Ocean. Additional light smoke moved south, blanketing the eastern Midwest and Southwest CONUS, and the western Southeast CONUS before reaching Mexico. Widespread agricultural burning continued this morning across the southeastern CONUS, which could have also contributed to the smoke observed in this area. Washington State… Wildfires continued in Washington State, with the fire in Chelan County producing moderate-to-heavy smoke, while the fire in Yakima County produced light-to-moderate smoke. Additional light smoke from the fires moved north towards southern British Columbia, merging with the smoke produced by the Canadian fires. 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
