DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 2330Z July 03, 2026
SMOKE: Canada… Widespread wildfire activity was observed across the Northwest Territories, Saskatchewan, and Manitoba generating a broad area of heavy-density smoke extending northward, before shifting southeastward across Nunavut towards northern Quebec. A broad area of moderate-density smoke was observed across western Canada, extending eastward across Ontario and Quebec before drifting southeastward into the Atlantic Ocean. Despite significant cloud cover, regional layers of heavy-density smoke were observed extending into the Gulf of St. Lawrence and southern Greenland. An extensive area of light-density smoke nearly covers the entirety of Canada east of British Columbia and Yukon and extends eastward across the northern Atlantic Ocean. CONUS… Multiple wildfires continued to burn across the Four Corners States this evening, producing heavy-density smoke drifting towards the northeast. A broader layer of light-to-moderate density smoke from these fires continued eastward, merging with the broader area of smoke dispersing southward from Canada. The combined plume dispersed across the entirety of CONUS east of the Rocky Mountains before drifting eastward into the Atlantic Ocean. Southern Mexico/Pacific 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 Mexico, extending east into the Gulf of America and southwest into the Pacific. 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
