DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1500Z September 24, 2025
SMOKE: Canada/PacificNW/Pacific Ocean/Central CONUS/Gulf of America/Eastern Mexico… An expansive area of mainly light to moderate smoke was seen blanketing an area from the Northwest Territories to Baffin Island to off the California coast, Great Plains, Gulf of America, and off the coast of the Maritime Provinces. The most concentrated areas of fire activity contributing to the area of smoke are in west-central Canada, the Pacific NW, and agricultural burning across the southeastern CONUS. The thickest smoke production was observed from the ongoing Canadian Wildfires and extending eastward to Hudson Bay. What is likely remnant smoke from this activity was also seen from Baffin Island into western Ontario then out eastward over the Great Plains,the Midwest, southern New England, and off the Maritime Provinces. The wildfire activity in the Pacific Northwest was helping to create the portion of the larger area that exists across Washington state and southern British Columbia and extends south-southwestward across western Oregon and off the Pacific Coast. Remnant smoke from this activity may also be observed across the Central CONUS. The agricultural burning across the southeastern CONUS and the Mississippi Valley, coupled with gas flaring activity in the Bay of Campeche, was adding to the smoke layer across the southeastern CONUS, Gulf of America, eastern and southern Mexico, Bay of Campeche, across the Isthmus of Tehuantepec into the Gulf of Tehuantepec and the Pacific Ocean offshore of Central America. The thickest smoke here was along the eastern coast of Mexico, where smoke was accumulating along the higher terrain just inland. Some early morning agricultural burning was noted as well with a couple smoke plumes observed across Georgia and South Carolina with smoke generally moving northeastward. Hosley 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
