THROUGH 1430Z September 20, 2025
SMOKE: Southwest Canada/Central Canada/Southeastern United States… Wildfires persisted throughout Canada in southern British Columbia, Alberta, and southern Northwest Territories. Moderate-to-heavy smoke drifted east from the western fires over southern Nunavut and northern Manitoba where it curved south towards the Dakotas and Great Lakes region but was obscured by clouds. Light smoke appeared to continue spread into the southeastern United States, from Texas to the Mid Atlantic, with some additional light smoke from agricultural burns in the region. Washington State… Fires continued across Washington State, producing moderate-to-heavy plumes which drifted east from the Olympic Peninsula and eastern Cascades. Moderate-to-light smoke spread across eastern Washington, northern Idaho and Montana, with some movement north to mix with smoke from fires in British Columbia and Alberta. Mills 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
