DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1500Z July 03, 2026
SMOKE: Canada… Widespread active fire activity was observed across the Northwest Territories, Saskatchewan,and Manitoba producing moderate-to-heavy density smoke plumes drifting westward to northward. Isolated fires in Ontario and Quebec were observed producing light-to-moderate density smoke drifting southwest to southeastward. A broad area of heavy-density smoke was observed across Nunavut and the Northwest Territories, extending eastward across southern Hudson Bay and extending across Quebec into the Atlantic Ocean to southern Greenland. An extensive area of light-to-moderate density smoke nearly covers the entirety of Canada east of British Columbia and Yukon and extends eastward across the northern Atlantic Ocean to Iceland. CONUS… Multiple areas of moderate-density smoke were observed across the central plains extending into the Great Lakes and northern New England and into Newfoundland and across the southeastern US extending into Virginia and extending into the Atlantic Ocean. An extensive area of light-density smoke nearly covers the entirety of CONUS east of the Rocky Mountains and extends east into the Atlantic Ocean. Southwestern U.S… Multiple wildfires continued to burn across the Four Corners States this evening, producing moderate-to-heavy density smoke drifting towards the northeast. Light smoke from these wildfires eventually merged with the broader area of smoke extending southward from Canada. Caribbean… Isolated fires in Cuba and the Dominican Republic were observed producing light-to-moderate density smoke drifting westward. 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. GM 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
