DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1640Z August 5, 2025
SMOKE: Canada/CONUS/Atlantic Ocean... Wildfires in the Northwest Territories, Saskatchewan, and Manitoba continued to produce dense smoke plumes which spread into large areas of moderate-to-heavy smoke that moved east across Ontario and Quebec. Widespread lighter smoke persisted across the northern region of the continent as it circulated to the east, reaching the Atlantic Ocean and across northeastern CONUS, before merging with the smoke over the Midwest region and from southern California. Western U.S... The Monroe Canyon fire in central Utah and the Dragon Bravo fire on the North Rim of the Grand Canyon National Park continued to produce light to locally moderate density smoke plumes that drifted northeast. Wildfires in north-central Nevada and northwestern Colorado were observed producing light to locally moderate density smoke also moving to the northeast. The Gifford Fire in southern California remained active and produced a large, moderate-to-heavy density smoke plume that drifted south over the western Channel Islands, extending south over the Pacific coast of Baja California, and then moving to the northwest with the weather system. DUST: Tropical Atlantic... Saharan dust was observed moving west from the Atlantic into the Caribbean. YL 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
