DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1500Z September 4, 2025
SMOKE: Western Canada/United States... Wildfires continued to burn across western Canada and the western United States with a large area of smoke extending from the Northwest Territories and Yukon, southeast through western Canada, the northern Rockies, central United States, and into the eastern United States. The smoke also extends south along the United States West Coast to central California. Within that area, localized moderate-to-heavy smoke was seen closer to the active wildfires over much of the region, but the largest concentration of moderate-to-heavy smoke was seen from far southeastern Alaska and the southwest portion of the Northwest Territories, extending southeast through British Columbia, the Pacific Northwest, the northern Rockies, and into the Central and Northern Plains of the United States. New Foundland and North Atlantic Ocean... An area of light smoke was seen east of New Foundland moving east into the North Atlantic Ocean. The source of this is believed to be a wildfire over southern New Foundland. 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
