DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1430Z September 14, 2025
SMOKE: Western Canada... Wildfires persisted overnight throughout British Columbia and Alberta, and the Northwest Territories. Moderate-to-thick density smoke originated in British Columbia and Alberta, drifted north and then east over southern Nunavut and Hudson Bay before spreading back south over Manitoba and Ontario. Smoke spreading north from fires in Washington and California also contributed to the smoke coverage observed moving across Canada. Western United States… Fires in central California and Washington State continued, contributing to a light coverage of smoke across the western United States. Light smoke drifted north to mix with heavier smoke in western Canada. Midwestern United States/Gulf Coast… Widespread light smoke from the Western US and Canada circulated south across Minnesota and spread into the Mississippi Valley. Light smoke moved offshore of east Texas and Louisiana, with some contribution from agricultural burns. Mills 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
