DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1430Z September 21, 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 from these fires drifted north over Nunavut, northeast across Saskatchewan and northern Manitoba, and into the Hudson Bay. Additional light smoke from the Canadian wildfires was observed spreading south into the northern United States before extending southeastward through the central and southeastern states, reaching the northern Gulf of America. Washington State… Fires continued across Washington State, producing light-to-moderate plumes which drifted northeast from Chelan County. The smoke spread across northern and eastern Washington, northern Idaho, and northern Montana, then dispersed eastward and northward, mixing with surrounding plumes from British Columbia and Alberta. 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
