DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 2330Z July 02, 2026
SMOKE: North America… Widespread active fire activity was observed across the Northwest Territories, central Canada, and western Quebec. Smoke from these fires, and remnant smoke from previous days’ fire activity, were contributing to an area of varying density smoke that was blanketing an area covering much of northern, central, and eastern Canada, the central and eastern CONUS, and the northern Atlantic Ocean. Moderate-to-heavy density smoke emanating from the wildfires across central Canada is moving generally northwestward, merging with the expansive moderate-to-heavy density smoke layer over northeastern Alberta, eastern Northwest Territories, and Nunavut. From there, a thin layer of moderate-to-heavy density smoke extends eastward across the Hudson Bay, northern Quebec, and Labrador, ultimately drifting into the northern Atlantic Ocean. Regional layers of moderate-to-heavy density smoke were also observed in central Quebec, New Brunswick, and southern Ontario drifting eastward. Light smoke from these wildfires also extended southward, dispersing across much of eastern CONUS. 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. 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
