DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 2330Z June 30, 2026
SMOKE: Canada... Multiple fires scattered across much of Canada continued to burn today, producing individual heavy-to-moderate density smoke plumes, as well a regional layer of heavy-density smoke that was observed dispersing over northern Alberta, the Northwest Territories, and Nunavut. Smoke from these fires accumulated into a widespread layer of moderate-density smoke extending across much of northern Canada and southward through Alberta, Saskatchewan, and Manitoba, ultimately reaching Montana. A separate layer of medium-density smoke was observed over the Hudson Bay, Quebec, Labrador, and Newfoundland before drifting southeast over the Atlantic Ocean. A large layer of light-density smoke from these wildfires covered much of Canada, drifting southward to join with light-density smoke produced by fires in the southwestern U.S. and eastward over the Atlantic Ocean. Southwestern US... Multiple large wildfires continued to burn across Arizona, New Mexico, Utah, and Colorado today, producing moderate-to-heavy smoke that traveled northeastward. Regional layers of medium-density smoke were observed dispersing northeastward from southeastern Utah to Michigan. A large area of light-density smoke from these wildfires joined with the light-density smoke covering much of Canada. This layer of light-density smoke dispersed eastward to the northeastern U.S., as well as southward toward Mexico. CONUS/Mexico/Pacific Ocean/Gulf of America/Atlantic Ocean... A layer of light-density smoke, consisting of smoke from today’s fire activity and remnant smoke from previous days, was observed over much of the United States and Mexico, extending from the Pacific Coast of California, over the Gulf, throughout central and eastern CONUS, and ultimately drifting westward into the Pacific Ocean. 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:http://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
