DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1430Z September 11, 2025
SMOKE: Western Canada/Pacific Northwest... Wildfires persisted throughout western Canada and the northwestern United States. Localized moderate-heavy density smoke in southern British Columbia was seen moving northeast across central Alberta, central Saskatchewan, and northern Manitoba as it makes its way towards northern Manitoba and the Hudson Bay. Light density smoke from the Canadian fires spread throughout the rest of Canada extending east over western Ontario, and continuing southeastward into the Midwestern United States, Southeastern United States, eastern Texas, and the Northern Gulf of America. California… The Garnet fire in California remained active this morning. This fire produced a small moderate-to-heavy smoke plume located near to the fire source. A larger light density smoke plume was observed moving north before dispersing east into central Nevada. Southeastern United States… Agricultural fires in the Southeastern United States contributed to the large area of the light density smoke that was moving southeast from the Canadian fires. 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
