DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 2330Z September 9, 2026
SMOKE: Canada... Due to significant cloud cover this evening, no individual smoke plumes were observed in Canada. However, a regional layer of remnant light density smoke was observed moving southward from central Nunavut into Saskatchewan and Manitoba, continuing into north central CONUS. Light smoke also moved eastward with the cloud column over the Hudson Bay and the Northwestern Passages, likely merging with cross-polar transport smoke over Baffin Bay and continuing over Greenland and the North Atlantic Ocean. A layer of remnant moderate density smoke was observed extending from Newfoundland and Labrador into the Labrador Sea, as well as southern Greenland. California… The Plaskett fire continued to burn this evening, producing moderate to heavy density smoke that extended westward into the Pacific Ocean. Idaho… A large area of smoke was observed in west-central Idaho from fires that ignited today. Plumes ranged from light to heavy density, eventually merging together and traveling eastward across the state. Mississippi Valley/Southeastern CONUS… Fires were active today across the Middle and Lower Mississippi Valley, with the highest concentration of smoke located in Arkansas. Numerous individual plumes ranging from light to heavy density smoke were observed, primarily traveling northward and northeastward. Scattered individual smoke plumes from agricultural fires were also observed across the Southeast this evening. CONUS… A broad layer of light-density smoke extended from the Ohio and Mississippi Valley into the Atlantic Ocean and back into the the Southeast before continuing into Texas and the Gulf Coast, ultimately merging with smoke from Mexico. Wyoming... The Moonshine Fire in southeastern Wyoming was observed producing moderate to heavy density smoke drifting northwestward. Mexico... A layer of light-density smoke from fires, industrial activity, and smoke from CONUS was observed over the western Gulf of America, Bay of Campeche, Gulf of California, and Pacific Ocean. BLOWING DUST: Caribbean... Dust from the Sahara Desert was observed lofting over the Atlantic Ocean this morning, drifting westward as far as the eastern Dominican Republic. Gaskill 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 map: https://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
