DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 2330Z September 10, 2025
SMOKE: Western Canada/Pacific Northwest... Wildfires persisted throughout western Canada and the northwestern United States. Localized moderate-heavy density smoke was seen in southern British Columbia, central Alberta, and northern Saskatchewan moving northeast making its way towards SE Northwest Territories and SW Nunavut. Light density smoke from the Canadian fires spread throughout the rest of Canada extending south over the Midwestern United States, continuing eastward into the Northeastern United States, Quebec, and Newfoundland. California… The Garnet fire in California remained active this evening. This fire produced a small heavy-moderate plume closer to the fire source which moved north towards western Nevada. A larger light-density smoke plume was observed from central California and moving west off the coast before dispersing north into the Pacific Ocean. Southeastern United States… Agricultural fires in the Southeastern United States contributed to the large area of the light-density smoke that was moving east from the Canadian fires. DUST: Light dust from the Saharan Desert was observed moving west into the eastern Caribbean reaching as far as eastern Dominican Republic. 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
