DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 2330Z 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 northeast towards the Arctic Archipelago and east across Ontario, Quebec, and the northeastern United States. Widespread lighter smoke persisted across the northern region of the continent as it circulated to the east, extending over the Atlantic Ocean. Western U.S... The Monroe Canyon fire in central Utah and the Dragon Bravo fire in Grand Canyon National Park continued to produce light-to-heavy density smoke plumes that drifted east. The Snowstorm wildfire in north-central Nevada and the Lee wildfire in northwestern Colorado were observed producing light-to-heavy density smoke. The smoke produced by the Snowstorm fire drifted northeast while the smoke from the Lee wildfire drifted eastward. The Gifford Fire in southern California remained active and produced a light-to-moderate 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 northeast with the weather system. DUST: Tropical Atlantic... Saharan dust was observed moving west from the Atlantic into the Caribbean. 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
