DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 2330Z August 29, 2025
SMOKE: Western and Central Canada... Wildfires continued in the Yukon, Northwest Territories, British Columbia, northwest Alberta, and northern Saskatchewan. Heavy smoke covered much of the Northwest Territories and northern Alberta and Saskatchewan, while moderate smoke was observed in the Yukon and BC. The smoke drifted north and mainly east, spreading into Nunavut, Manitoba and thinning as it continued expanding northeast into the Arctic and south towards the Great Lakes region. Western United States... Wildfires in California and Oregon were producing plumes of moderate-to-heavy smoke which spread mainly north and circulated east, covering Washington, Idaho and Nevada. There was some light density smoke spread offshore near Santa Barbara from fires in Southern California. Smoke from the western states expanded and merged with smoke from Canada, creating a large area of light coverage across the Pacific coast, the Rocky Mountains, and Canada. Midwestern United States/Mid-Atlantic… Light smoke moved south over Minnesota and Wisconsin from Canada, curving to the east south of the Great Lakes. Proscribed fires throughout the Mississippi Valley contributed to the smoke spread as it continued east towards the Mid-Atlantic states and moved offshore. DUST: Saharan Dust was observed east of the Caribbean and lesser Antilles. 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
