DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1500Z August 2, 2026
SMOKE: Canada… Wildfires in southern British Columbia continued to produce moderate-to-heavy density smoke plumes this morning, contributing to a regional area of heavy density smoke that drifted northeast across Alberta, Saskatchewan, Manitoba, and Ontario before moving north into southeastern Nunavut. Some of this heavy-density smoke also drifted south from southern Manitoba and southwestern Ontario into the northern Midwest of CONUS. As the heavy-density smoke dispersed, it transitioned into a broader area of medium-density smoke that continued to drift southwestward across the Southern Great Plains. 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 southward to merge with light-density smoke over CONUS, ultimately moving east into the southeastern states. CONUS… Numerous wildfires in Oregon, Washington, Idaho, and Montana continued to burn this morning. Smoke from these fires extended northeastward, contributing to the large area of heavy smoke extending northeastward across Canada before drifting back southeastward across the Great Plains. This smoke contributed to the medium- and light-density smoke observed across much of the Great Plains, with the light-density smoke extending south across Texas and into Mexico and reaching central Mexico. Mexico… The plume of light-density smoke was observed spreading southward from CONUS into eastern and central Mexico toward 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
