DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 2330Z August 2, 2026
SMOKE: Canada… Wildfires in southern British Columbia continued to produce moderate-to-heavy density smoke plumes this evening, contributing to a regional area of moderate-to-heavy density smoke that drifted northeast across Alberta, Saskatchewan, Manitoba and Ontario before moving north into southeastern Nunavut. Some of this moderate-density smoke also drifted southward from southern Manitoba and western Ontario into the Midwestern United States. A widespread layer of light-density smoke covered much of central and northern Canada, with additional contributions from wildfires in Northwest Territories. The smoke extended westward into the Pacific Ocean and southward to merge with light-density smoke over CONUS, ultimately moving east into the southeastern states before drifting offshore into the Atlantic Ocean. CONUS… Numerous wildfires in the western CONUS, including the Widemouth 2 Fire in central Utah, continued to burn this evening, producing individual moderate-to-heavy density smoke plumes. Smoke from these fires extended northeastward, contributing to the large area of smoke extending northeastward across Canada before drifting back southeastward across the Midwestern U.S. This smoke also contributed to the light-to-moderate density smoke observed across much of the Great Plains, with the light-density smoke extending south across Texas and into Mexico. Mexico… The plume of light-density smoke was observed spreading southward from CONUS into eastern and central Mexico before drifting offshore 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
