DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0100Z July 13, 2025
SMOKE: Alaska/Canada/North-Central United States/Atlantic Ocean... Wildfire activity today is mainly analyzed across two areas: Alaska and central Saskatchewan/Manitoba. In addition to these two areas, a large wildfire along the BC/NW Territory border is also analyzed. From these fires, thick smoke is being produced. Smoke from a majority of the fire activity is moving east-southeast to east from the parent activity. The smoke is then moving around a cyclone over western Ontario, both moving east-northeast over northern Alberta Hudson Bay, Baffin Island, and far northern Quebec, and moving southeast into the Upper Midwest and the Great Lakes. The southern stream is becoming incorporated into the cyclone, which is helping to concentrate the smoke over western Ontario. Some smoke is also seen moving northward around the cyclone over eastern Ontario, James Bay, and southern Quebec. These two streams meet up over Labrador, from where the smoke then bifurcates again, with some smoke moving into Greenland and some over Newfoundland. The smoke over Greenland then dives back southward and moves out over the open North Atlantic. From here, smoke becomes lighter and begins to move northward toward Iceland. Western CONUS/Southern British Columbia… More than a dozen wildfires are analyzed across the western CONUS from Washington State to New Mexico. Wildfires are more widespread across the southwest, as wildfires are more isolated across the Pacific Northwest. The thickest smoke producers were wildfires across the Colorado/Utah border and north-central Arizona. Smoke from fires in extreme southern BC, Washington State, Idaho, and Colorado was moving mainly east-southeastward, while smoke from fires across Utah, Arizona, and Nevada were mainly moving southward. Smoke across northern California was moving northward to northwestward. An area of remnant smoke was being produced across far southern Nevada, northern Arizona, and west-central New Mexico with contributions likely from the past day or two as well. BLOWING DUST: Tropical Atlantic/Caribbean Sea/Gulf of America/Southeastern CONUS… Saharan Dust was observed extending westward from the Sahara across the Tropical Atlantic and Caribbean and over the Bahamas, Yucatan, Gulf of America, Florida, and the southeastern CONUS. Southern Alberta… A blowing dust plume was observed coming off the dried portions of Kenilworth Lake in southeastern Alberta with the dust reaching southern Saskatchewan. Northwestern Sonora… A dust plume was observed moving east-northeastward from a source in the Caborca Municipality of Sonora. Hosley 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
