DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0125Z June 4, 2026
SMOKE: Manitoba/Ontario/Northeastern CONUS... A broad area of light-density smoke from fire activity and remnant smoke from previous days was observed extending from central Manitoba eastward towards southern Quebec and southeastward over the northeastern United States. An area of moderate-density smoke was observed over central Ontario and Quebec. Despite significant cloud cover in the region, multiple wildfires in western Ontario were observed generating individual moderate-to-heavy smoke plumes moving eastward. Northwest Territories/Alberta... Wildfires in south-central Northwest Territories and northern Alberta were observed producing light-to-moderate density smoke plumes drifting northwestward. Sonora, Mexico... A wildfire in eastern Sonora was observed producing light-to-heavy density smoke extending northeastward into eastern Sonora and Chihuahua. Southeastern CONUS... Scattered fires were observed producing small light-density smoke plumes across the Carolinas, Georgia, and Florida generally drifting southwestward. SMOKE/AEROSOL: Mexico/Pacific Ocean/Gulf of America... Fire activity, aerosol emissions from gas flaring and other industrial activities, and remnant smoke from previous days contributed to a widespread layer of light-density smoke and aerosols across south and central Mexico. The smoke extended southwest into the Pacific Ocean, and north across the western Gulf of America, ultimately reaching southern Texas. A large area of moderate-density smoke was observed in the southern Gulf of America drifting southward across Mexico and into the Pacific Ocean. Additional area of moderate-density smoke was observed on the Pacific coast of southern Mexico. YL 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
