DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0220Z June 1st, 2025
SMOKE: Canada/Midwestern U.S... Wildfire activity remained extensive across central Canada, with numerous large fires observed in northeastern British Columbia, Northern Alberta, far southern Northwest Territory, Central Saskatchewan, much of Manitoba, and western Ontario. Moderate-to-heavy density smoke from these sources continued to blanket central and northern Canada and expanded further south and east during the day. The thickest smoke was concentrated from eastern Nunavut southward through Hudson Bay into Ontario, the Great Lakes, and the Ohio valley. Moderate-to-light density smoke spread broadly through the Midwest, Tennessee Valley, southeastern U.S., and into the Gulf of America. Light smoke curled eastward into the western Atlantic and reached as far south as the northern Caribbean. Additional southward transport continued into Texas, Louisiana, and Florida, merging with smoke from seasonal agricultural fires in Mexico and Central America. North Pacific/Far Western Canada... Ongoing smoke from wildfire activity in southeastern Russia (north of eastern Mongolia; Buryatia and Sakha Republics along with Zabaykalsky Krai and Amur and Irkutsk Oblasts) continued to extend northward into Siberia then diving south across the Kamchatka Peninsula and out over the Northern Pacific Ocean before merging with the plumes over British Columbia and into far northwestern Alberta. AEROSOL/SMOKE: Central-Southern Mexico/Southern Gulf of America... An area of light-density smoke and aerosols, attributed to widespread seasonal fire activity, volcanic emissions, and industrial sources throughout central and southern Mexico, was observed extending over Central-Southern Mexico and the Pacific Ocean off Mexico’s southern coastline. Some of the aerosol layer may be reaching as far north as the US Gulf Coast. DUST: A large plume of light density Saharan Dust was observed extending westward from the African Coast to the eastern Caribbean. Cardona 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
