DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 2330Z September 20, 2025
SMOKE: Southwest Canada/Central Canada/Southeastern United States… Wildfires persisted throughout Canada in southern British Columbia, Alberta, and southern Northwest Territories. Light-to-moderate density smoke drifted east from the western fires over Nunavut and northern Manitoba into the Hudson Bay and traveled south towards Great Lakes region but was obscured by clouds. The light smoke appeared to continue spread into the Southeastern United States, the northern portion of the Gulf of America, and the Atlantic Ocean, mixing with some additional light smoke from the agricultural burns in the region. Washington State… Fires continued across Washington State, producing moderate-to-heavy plumes which drifted northeast from the Olympic Peninsula and eastern Cascades. Light-to-moderate smoke spread across eastern Washington, northern Idaho and northwestern Montana, with some movement north to mix with smoke from the fires in British Columbia and Alberta. 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
