DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1430Z September 29, 2025
SMOKE: Northwest Territories/Central Canada... Wildfires continued to burn across northern and central Canada, with smoke-producing activity observed across the Northwest Territories, Alberta, and western Saskatchewan. Heavy cloud cover obscured some of the smoke produced by the wildfire in Canada this morning. However, moderate smoke continued to be observed dispersing locally in central Alberta and western Saskatchewan, which then thinned to light smoke as it drifted towards southern Manitoba, southern Ontario, and southern Quebec. Light smoke from these fires was also observed moving south into the Northern Plains, Midwest CONUS, and Southwest CONUS, reaching Texas. Additional light smoke from the Northwest Territories was observed moving east over southern Nunavut and northern Manitoba before being obscured by some clouds over the Hudson Bay. Pacific NW... Wildfires also continued to burn across the Pacific Northwest, from western Oregon and central Washington to western Idaho and Montana. Despite moderate cloud coverage obscuring the full extent of the smoke plume, light smoke was seen being produced by the wildfires in central Washington and southwestern Oregon. Light smoke drifted northeastward across Washington, northern Idaho, northern Montana, and eventually merging with the light smoke from 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
