DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 2330Z September 27, 2025
SMOKE: Northwest Territories/Central Canada... Wildfires continued to burn across northern and western Canada, with smoke-producing activity observed across the Northwest Territories central Alberta, and western Saskatchewan. Light smoke from these wildfires moved east across the Northwest Territories and then curved south, drifting across Central CONUS, the Great Lakes region, and the Southeastern United States until it eventually makes its way over the Bay of Campeche. Pacific NW/Montana... Wildfires also continued to burn across the Pacific Northwest, from western Oregon and central Washington to western Montana. Despite moderate cloud coverage obscuring the full extent of the smoke plume, the heaviest smoke was seen being produced by the wildfires in central Washington. Light-to-moderate smoke drifted northeastward across Washington, northern Idaho, northwestern Montana, and southwestern Alberta, eventually merging with the light smoke from the Canadian fires. Pacific Coast/Southwestern Oregon… The Moon Complex fire in southwestern Oregon was producing moderate-to-heavy smoke this evening. The thick smoke moved west then immediately south along the Pacific Coast and northeast as it makes it way across western Oregon. The smoke plume’s full extent was not visible due to clouds along the southern 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
