DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 2330Z September 3, 2025
SMOKE: Western Canada/Western United States... Wildfires continued to burn across western Canada with the largest fires and heavy smoke production in the Northwest Territories and British Columbia. Due to heavy cloud cover, most of the smoke seen yesterday over the Northwest Territories were obscure. There was a long, thick plume of smoke from the fires in central British Columbia traveled southeast over southern Alberta and Montana. Light to moderate density smoke covered much of British Columbia, Alberta, and spread south over much of the northwestern United States from the Pacific Coast to the Midwestern U.S. US West Coast... Wildfires in California, Oregon, and Washington State were observed producing moderate to heavy density smoke plumes which moved to the north and west. The largest plumes were observed in central California and throughout Washington State. The smoke plumes from the wildfires in Washington State, northern Idaho, and western Montana were also observed merging with the light-to-heavy density smoke traveling southeast from British Columbia. Libby 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
