DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 2330Z 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 the Midwestern United States. Moderate-to-heavy density smoke was concentrated over Manitoba and eastern Ontario, spreading south into the Dakotas, Minnesota, Wisconsin, and Michigan. Moderate-to-heavy density smoke was also seen over the Northeastern United States, New Brunswick, Newfoundland and Labrador, Nova Scotia, and North Atlantic Ocean. Additionally, the wildfire observed producing a smoke plume in Newfoundland merged with the light-to-heavy density smoke over the north Atlantic Ocean as it circulates towards the east. California/Colorado/Southwestern CONUS... Wildfires in southwestern CONUS remained active, 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. Light-to-heavy smoke were produced by these wildfires with moderate-heavy concentrated near the fires. Light density smoke from most of these fires merged together with the smoke produced by the Canadian wildfires with the weather system. DUST: Caribbean... Light-to-moderate dust from the Saharan Desert was observed moving westward across the Lesser 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
