DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1430Z August 1, 2025
SMOKE: Alaska/Canada/North Atlantic Ocean... A large area of smoke persisted across the northern region of the continent, and drifted towards the east from the Northwest Territories to the North Atlantic. Wildfires in the Northwest Territories, Saskatchewan, and Manitoba continued to produce large, dense plumes of smoke that moved east across Ontario and Quebec, thinning toward the Atlantic. The highest concentration of smoke plumes were observed over eastern Alberta, Saskatchewan, Manitoba, and western Ontario, with a southeast trajectory over the Great Lakes region. Arizona/Utah/Central United States... The Monroe Canyon fire in central Utah and the Dragon Bravo fire in northern Arizona continue to burn, emitting light-to-moderate smoke over Wyoming, Colorado, Montana, Nebraska and the northern Great Plains region, with moderate density smoke reaching as far as the Great Lakes, and merging with the larger area of smoke produced by the Canadian wildfires as the smoke drifted northeast. DUST: Tropical Atlantic Ocean and Caribbean Sea... Light Saharan dust was observed over parts of the tropical Atlantic Ocean, expanding west over the Lower Antilles. Libby 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
