DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 2330Z August 10, 2026
SMOKE: Canada… Wildfires in the Northwest Territories continued to produce a localized layer of moderate-to-heavy density smoke this evening. Wildfires in southern British Columbia produced moderate-to-heavy density smoke plumes that joined with smoke from fires in the Pacific Northwest of the United States. The smoke drifted east-southeastward, contributing to a widespread layer of moderate-to-heavy density smoke that extended eastward across much of southern Canada. A separate layer of remnant heavy-density smoke was also observed over Nova Scotia and Newfoundland. A layer of light-density smoke covered most of southern and western Canada, extending from the Northwest Territories and British Columbia to Newfoundland and Labrador, as well as over northern Nunavut. Light-density smoke drifted eastward over the Atlantic Ocean, as well as southward to join with light-density smoke covering CONUS. Pacific Northwest… Wildfires in Washington and Oregon continued to produce moderate-to-heavy density smoke plumes. Smoke from these fires drifted eastward and contributed to a widespread layer of moderate-to-heavy density smoke across much of northern CONUS. The layer of heavy-density smoke from these fires traveled as far eastward as Pennsylvania. CONUS… In addition to the numerous wildfires in the Pacific Northwest, fires located in northern California, Idaho, Utah, New Mexico, Montana, Kansas, and South Dakota all produced smoke plumes that contributed to a widespread layer of moderate-to-heavy density smoke that drifted eastward across the central United States, traveling as far south as Texas and Oklahoma before continuing into the Mid-Atlantic and Northeast, eventually drifting eastward over the Atlantic Ocean. Light-density smoke was observed covering nearly all of CONUS before drifting southwestward into the Pacific Ocean, southward over Mexico, eastward into the Atlantic Ocean, and northward to join with light-density smoke over Canada. Mexico/Gulf of America/Pacific Ocean… Light-density smoke was observed covering much of Mexico, eventually drifting southwestward into the Pacific Ocean, and southward over Guatemala, Belize, and the Gulf of America. BLOWING DUST: Caribbean… Light blowing dust was observed drifting westward from the Sahara Desert towards the Caribbean, reaching as far west as the Haiti and Cuba. Marrs 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
