DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 2330Z September 13, 2025
SMOKE: Central Canada/Pacific Northwest... Wildfires persist throughout Alberta, the Northwest Territories and Saskatchewan, producing moderate-to-heavy smoke circulating to the east through Southern Nunavut and Northern Manitoba. Fires in central and eastern Washington state also contributed to the smoke coverage seen across Canada. Additional smoke from California was observed moving south-west off the coast before dispersing north into the Pacific Ocean. California… Fires in central California produced moderate-to-light smoke which dispersed to the north, spreading light smoke across the northern region of the state and western Oregon and merging into the larger area of light smoke coverage over Washington and British Columbia. Midwestern United States/Central Gulf Coast… Smoke from Canada generated a large area of light density smoke observed moving south across Minnesota and Wisconsin, reaching Texas and Louisiana. Light smoke moved offshore and circulated back towards the northeast and across Ohio, with some contribution from agricultural burns. 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
