DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 2330 July 04, 2026
SMOKE: Canada… Wildfire activity in the central Nunavut, northeast Saskatchewan and northwest Manitoba was observed producing large heavy-to-moderate smoke across the region. Smoke plumes moved north, then northeast across Nunavut before shifting south into Hudson Bay and east into Quebec. Wildfires in the Northwest Territories also produced heavy-to-moderate smoke that moved east and northeast into Nunavut. Fires in Ontario and Quebec were also observed producing individual heavy-to-moderate smoke plumes. Moderate smoke was observed over the wildfire areas and across much of Canada. 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. Large plumes of heavy smoke spread through valleys and moved northeast from fires in Colorado, contributing to a larger area of moderate smoke that moved east-northeast from Utah through Nebraska and Kansas to Indiana. 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 and Central America… An area of moderate smoke was observed over west-central Mexico and along the eastern coast of Mexico, extending south into Guatemala. The smoke dispersed into a broader area of light-density smoke that moved into the Gulf of America. Hernandez 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
