DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 2330Z September 16, 2025
SMOKE: Western Canada/Midwestern and Southeastern CONUS…. The combination of continued wildfires over western Canada, although to much a lesser extent than what was seen a few weeks back. The light-to-moderate smoke remnants produced the western Canadian wildfires extended across southern Saskatchewan, Ontario, southern Quebec, and the northern portion of the United States and into the North Atlantic Ocean. A portion of that area of smoke was also drawn southeast into the Midwestern and Southeastern United States and also extending offshore over the Northern Gulf of America. Within this large area of smoke, a few areas of moderate density smoke were seen over portions of northeastern Montana extending east over North Dakota and also from Nova Scotia extending east into the North Atlantic Ocean. Pacific Northwest… Multiple wildfires were also observed in the Pacific Northwest, mainly in the Olympic Peninsula of Washington State and southern British Columbia, producing light-to-heavy smoke plumes traveling in the northern direction. Heavy smoke from the wildfire in the Olympic Peninsula remains concentrated near the source while the light-to-moderate smoke extends over the southern tip of Vancouver Island. Central California… The wildfire in central California continued to produce a localized light-to-moderate smoke plume that was concentrated near the fire source. 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
