DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 2330Z September 1, 2026
SMOKE: Canada… Despite significant cloud cover this evening, light-to-moderate density smoke was observed over the Northwest Territories. The smoke moved northeastward into Nunavut and southward into Alberta, Saskatchewan, and Manitoba. Light-to-heavy density smoke from fires in the Pacific Northwest of the United States drifted northward into southern British Columbia and Alberta. Light-density smoke drifting northward from the United States was observed over southern Ontario. A separate layer of remnant smoke was also observed drifting southeastward over the Hudson Bay, central Quebec, and New Brunswick. U.S. Pacific Coast… Wildfires across Washington, Oregon, Idaho, and Montana produced moderate-to-heavy density smoke plumes throughout the Pacific Northwest region. A layer of light-density smoke from these fires dispersed locally before moving northward into Canada and southward into northern Nevada. The Plaskett Fire in Monterey County, California was observed producing localized moderate-to-heavy density smoke, with light-density smoke dispersing northeastward within the state and southwestward into the Pacific Ocean. Central and Eastern CONUS… Fires were active across central and southeastern CONUS this evening. The fires produced multiple localized moderate-to-heavy density smoke plumes in Oklahoma, Arkansas, and Alabama. Smoke from these fires contributed to an area of light-to-moderate smoke. The moderate-density smoke layer covered Texas to Nebraska along its western edge, and drifted eastward over much of the southern and mid-Atlantic United States before drifting over the Atlantic Ocean. A larger layer of light-density smoke spanned from the Pacific coast of southern Mexico to southern Ontario, ultimately drifting westward over the East Coast of the United States. Mexico… A layer of remnant light-density smoke from fires and industrial activity was observed across the Gulf of America and Mexico. A layer of light-density smoke was also observed over the Pacific Ocean off the coast of Baja California and Baja California Sur. 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
