DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 2330Z September 18, 2025
SMOKE: Canada, Southeastern and Northeastern United States.. Wildfires continued to burn across Canada and the western United States. Moderate-to-heavy smoke from the fires in southeastern British Columbia and northeastern and central Alberta was observed dispersing further northeast into the the Northwest Territories and Nunavut. A lighter smoke plume from these fires extends from the Northwest Territories through Alberta, Saskatchewan, and southern Manitoba, and is observed dispersing southeast into the Southeastern United States and east towards the Midwestern and Northeastern United States. While the fires in western Canada remain active, their scale is significantly less than what was observed in previous weeks. Washington State… The fires in central and northeastern Washington State produced an area of light-to-moderate density smoke that extended northeast and merged with the smoke plumes observed in southern and eastern British Columbia and Alberta. A light-to-moderate smoke plume produced by the wildfire in the Olympic Peninsula was also seen extending south through western Oregon and into the Pacific Ocean. GL 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
