DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1500Z July 05, 2026
SMOKE: Canada… Wildfire activity in the central Northwest Territories, southern Nunavut, northeast Saskatchewan and northwest Manitoba was observed producing large light-to-moderate smoke this morning. Smoke plumes in this region moved generally east-northeast before converging with another plume that was traveling west over the Hudson Bay. Fires in Ontario and Quebec were also observed producing individual heavy-to-moderate smoke plumes. An area of remnant heavy-density smoke was observed over eastern Nunavut, the Hudson Bay, and northern Quebec. The plume persisted over the region, with additional smoke sourced from today’s fires in Quebec. A larger area of moderate smoke stretched into the Northwestern Passages and the Labrador Sea. It contributed to a larger area of light smoke that moved south into the United States and merged with existing smoke, extending from the Midwest to the Atlantic Coast. CONUS… Multiple wildfires continued to burn in the western mountain region of the United States this morning. Localized plumes of moderate-to-heavy density smoke spread from fires located in Utah and Colorado. A large area of light-density smoke, with contributions from Canada, covered most of the United States and extended east into the Atlantic Ocean. Mexico/Central America/Gulf of America… A layer of light-density smoke from remnant fire activity was observed over Baja California Sur extending into the Pacific Ocean and reaching the shoreline of western Mexico. An area of light smoke from fires, aerosols, and industrial sources was also observed in central Mexico and Guatemala, crossing the Isthmus of Tehuantepec and continuing into the Gulf of America. Gaskill 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
