DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1500Z September 6, 2026
SMOKE: Canada… Despite significant cloud cover, wildfires in the southern Northwest Territories continued to burn this morning, which produced a localized area of medium-to-heavy density smoke drifting southwestward into British Columbia. A layer of light-density smoke was observed drifting eastward from the northern Northwest Territories into Nunavut and over the Hudson Bay, before traveling southwestward to span northern Manitoba to northeastern British Columbia. A separate layer of light-density smoke was observed over the Davis Strait, drifting eastward into Greenland. Light-to-moderate density smoke drifting northward from CONUS was also observed over southern Manitoba and Ontario. CONUS… A layer of remnant light-to-moderate density smoke from yesterday’s fire activity was observed across much of central and eastern CONUS this morning. The smoke drifted northward into Canada and southwestward toward Mexico, as well as eastward over the southern and mid-Atlantic United States, ultimately drifting offshore into the Atlantic Ocean. Western United States… The Plaskett Fire in Monterey County, California was observed producing light-to-moderate density smoke drifting southwestward over the Pacific Ocean. Despite moderate cloud cover, fires in central Washington were observed producing a localized area of light-to-moderate density smoke. Southeastern United States… Remnant smoke from yesterday’s fire activity in the Southeastern U.S. contributed to a large layer of moderate-density smoke that drifted eastward towards the Atlantic Ocean. Mexico/Gulf of America/Pacific Ocean... A layer of light-density smoke from fires, industrial activity, and smoke from CONUS was observed over the Gulf of America and along the eastern coast of Mexico. The smoke extended southward over the Isthmus of Tehuantepec and westward across Mexico before dispersing into the Pacific Ocean. GL 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
