DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 2330Z September 11, 2026
SMOKE: Canada… A regional layer of light-density smoke was observed stretching from central southern Canada eastward over Nova Scotia and northeastward over Hudson Bay and into the Labrador Sea. An area of moderate density smoke was observed over the Hudson Strait and extending southward into parts of Quebec and Ontario. Pacific Northwest… Isolated fires in Washington, Oregon, Idaho, and British Columbia were observed producing locally light to heavy density smoke plumes. 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. Light density smoke from Canada crossed over the Great Lakes and into the Midwest. A broad area of moderate density smoke was observed off the mid-Atlantic coast and extending in southeastern Virginia and northeastern North Carolina and southward from Canada into Maine. California… The Lucas Fire was observed producing moderate to heavy density smoke that drifted eastward before dissipating over central Nevada. 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, Baja California, and the Pacific Ocean. A layer of medium-density smoke was observed over the Bay of Campeche and Isthmus of Tehuantepec, sourced from today’s industrial activity. BLOWING DUST: Caribbean... Moderate density blowing dust from the Sahara Desert was observed lofting over the Atlantic Ocean north of the Lesser Antilles, while light density dust drifted westward as far as Cuba. Monaghan 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
