THROUGH 2330Z September 26, 2025
SMOKE: Northwest Territories/Central Canada... Wildfires continued to burn across northern and western Canada, with the smoke-producing activity observed across the Northwest Territories and northern Alberta. The thickest smoke production was observed from a large wildfire just west of Great Slave Lake moving east-northeast across the Northwest Territories. Light density smoke was seen from northern Alberta, with smoke moving east then east-southeast eventually making its way over central CONUS/Mississippi Valley. Pacific NW/Big Sky Country... Wildfires also continued to burn across the Pacific Northwest, from northern Oregon and central Washington to western Montana. Due to heavy cloud coverage in the area, smoke was not visible this morning. Pacific Coast… The Moon Complex fire in southwestern Oregon was producing thick smoke this morning. The thick smoke moved west then immediately south along the Pacific Coast. The smoke plume’s full extent was not visible due to clouds along the southern Pacific Coast. Rodriguez 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
