DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1430Z August 2, 2025
SMOKE: Alaska/Canada/Great Lakes... Widespread light smoke persisted across the northern region of the continent as it circulated to the east, across the Arctic and back. Wildfires in the Northwest Territories, Saskatchewan, and Manitoba continued to produce dense plumes of smoke which spread into large areas of thick-to-moderate smoke and moved east across Ontario and thinned as it reached eastern Quebec. Smoke also spread south into the Great Lakes region and northeastern United States. Arizona/Utah/Central United States... The Monroe Canyon fire in central Utah and the Dragon Bravo fire in northern Arizona continued to produce thick smoke plumes that spread and dissipated to the east across Southern Wyoming, Colorado, and met with smoke from the north as it moved towards the Great Lakes. The smoke expanded and produced light density coverage from Texas to Maine. Pacific NW… The Bear Gulch fire on the Olympic Peninsula of Washington State continued to produce moderate-to-heavy smoke which spread east into lighter smoke across the Puget sound and along the Cascade range. A fire on Vancouver Island also generated a thick density plume that moved east and south into the Fraser Valley, and contributed to the wider area of light smoke across the Pacific NW. California… The Gifford Fire in southern California produced a large, thick density smoke plume that drifted south over the western Channel Islands and Pacific Ocean. Moderate smoke spread throughout the southern central valley and traveled towards southern Nevada. 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
