DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1655Z August 11, 2025
SMOKE: Canada/Atlantic Ocean/CONUS... Wildfires in northwestern and central Canada continued to produce dense smoke plumes that blanketed most of North America, drifting east to the Atlantic Ocean and over central and eastern CONUS. Moderate-to-heavy density smoke was concentrated over eastern Saskatchewan and western Manitoba, spreading south into the Dakotas, Minnesota, and western Wisconsin. Moderate-to-heavy density smoke was also seen over Newfoundland and Labrador, Nova Scotia, and North Atlantic Ocean. Additionally, wildfires were observed producing smoke plumes in Newfoundland and New Brunswick as they merged with the light-to-heavy density smoke over the north Atlantic Ocean as it circulates towards the east. Southwestern CONUS... Wildfires in southwestern CONUS remained active this morning, including the Gifford Fire in southern California; the Monroe Canyon Fire in central Utah; the Dragon Bravo Fire in northern Arizona; The Billy, Bronco, and Indian Creek Fires in southeastern Arizona; the Lee Fire in northwestern Colorado; and the Stoner Mesa Fire in southwestern Colorado. Moderate-to-heavy smoke was observed near the sources. Light density smoke from most of these fires merged together with the smoke coming south from Canada with the weather system. DUST: Caribbean... Light Saharan dust was observed moving westward across the Lesser Antilles. 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
