DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1430Z 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 NW Territories were obscure. There was a long, thick plume of smoke emitted to the west from fires in central British Columbia. Light to moderate smoke covered much of British Columbia, Alberta, and Saskatchewan, and spread south over the northwestern United States from the Pacific to the Dakotas. US West Coast... Wildfires in California, Oregon, and Washington were observed producing moderate to thick plumes of smoke which moved to the north and west, merging with smoke from Canada. The largest plumes were observed in central California, throughout Washington State, with some contribution from fires in northern Idaho as well. Rodriguez 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
