DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1500Z August 1, 2026
SMOKE: Canada… Wildfires in southern British Columbia continued to produce medium-to-heavy density smoke plumes this morning, contributing to a regional area of heavy density smoke that drifted north-northeast over Alberta, northern Saskatchewan, and into Manitoba. As the regional area of heavy-density smoke dispersed, it expanded into a broader area of medium-density smoke and move southwestward into CONUS. Fires from the Northwest Territories also contributed to this moderate-density plume. A widespread layer of light-density smoke covered much of central and northern Canada. The smoke extended southward to merge with light-density smoke over CONUS, and eventually drifted offshore into the Atlantic Ocean. CONUS… Numerous wildfires in Oregon and Washington were observed producing individual medium-to-heavy density smoke plumes. Smoke from the fires in these fires contributed to a large area of medium-to-heavy density smoke that extended northeastward into Canada before drifting back southward across the Great Plains. Wildfires in Nevada also continued to burn this morning, producing a localized medium-to-heavy density smoke plume along the Nevada-Utah border. As the plume drifted eastward, it merged with the broader area of moderate-density smoke extending south from Canada. The area of medium-density smoke continued southward before turning east across the southeastern CONUS. It also extended south along eastern Mexico. Mexico… The plume of light-density smoke was observed spreading southward from CONUS into eastern Mexico, ultimately reaching the Isthmus of Tehuantepec. The smoke also moved west from central Mexico into the Pacific Ocean. Hernandez 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
