DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0100Z June 24, 2025
SMOKE: Alaska/Yukon/Central Canada/Central and Eastern United States/Atlantic Ocean… Wildfire activity across Alaska and northwestern Canada continued to generate moderate to thick smoke that spans across Alaska, much of Western and Northern Canada, and as far out as the Davis Strait and Greenland. The thickest smoke is emanating from the wildfire activity near the Northwest Territory/BC/Alberta triple point, from which the smoke is moving anywhere from northwest to east-southeast. The main area of thicker smoke resides over southern Yukon into central and northern Alaska, from where it is moving out over the Chukchi Sea. It is also along this corridor where a relatively high density of wildfires exist. Some of the remnant light smoke diving down from the Arctic over Nunavut, Hudson Bay, and northern Quebec was observed moving east-southeastward over the Maritime Provinces and the Davis Strait, with it likely that some is drawn northward from there over Greenland. Northern Mexico/Southwestern United States/Rocky Mountains... Fires across the western CONUS and extreme northern Mexico are aiding in producing smoke plumes (along with remnant smoke from these fires from the previous couple days) that are moving north to northeastward, with smoke from these fires reaching as far as northern Minnesota, central Saskatchewan, and central British Columbia. The remnant smoke from these fires may be merging with remnant smoke from Alaska and western Canada. Mid-Mississippi Valley… Scattered to widespread agricultural burning was observed from the Missouri Bootheel south-southwestward into northeastern Arkansas. The light smoke from these fires was seen moving north-northeastward into southern Illinois, where one or two agricultural burns were also noted with light smoke moving north-northwestward. 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
