DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 2330Z July 01, 2026
SMOKE: Canada... Multiple fires scattered across much of Canada continued to burn today, producing individual moderate-to-heavy density smoke plumes, as well a regional layer of heavy-density smoke that was observed dispersing east from Nunavut across the Hudson Bay, eventually reaching northern Quebec. A smaller, separate layer of heavy-density smoke was observed over the Hudson and western Quebec. Smoke from these fires accumulated into a widespread layer of moderate-density smoke extending across much of northern Canada, extending eastward over the Hudson Bay, Quebec, Labrador, and Newfoundland before drifting southwest over the Atlantic Ocean. Scattered fires across western Quebec were observed producing moderate-to-heavy density smoke plumes drifting eastward within the province, mixing with the broader area of smoke from western Canada. Light smoke from these wildfires also extended southward, merging with the smoke produced by fires in southwestern U.S. and dispersing across much of eastern CONUS. Southwestern US... Multiple large wildfires continued to burn across Arizona, New Mexico, Utah, and Colorado this evening, producing moderate-to-heavy smoke that drifting northeastward across the Midwestern U.S. into Ontario, eventually merging with the broader area of smoke covering much of Canada. Northern CONUS… A regional layer of medium-density smoke from the wildfires in Canada was observed drifting southeastward from the northeastern U.S. into the Atlantic Ocean. Cuba… Scattered fires across Cuba were observed producing light-to-moderate density smoke drifting generally southwestward. 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. 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: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
