DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1510Z May 29, 2025
SMOKE: Canada/Northern U.S. Plains/Great Lakes/Atlantic Ocean… Extensive wildfire activity in east-central Saskatchewan, west-central Manitoba, and western Ontario continued to generate large swathes of moderate to heavy smoke. The core of heavy smoke remained concentrated over southern Manitoba, stretching eastward across northern Ontario, southern Hudson Bay, and into Quebec and Newfoundland. A broad plume of moderate density smoke extended southward into the northern U.S. Plains, reaching as far as Iowa, Minnesota, Wisconsin, and Michigan, with lighter smoke spread across the northeastern U.S. and over the Atlantic Ocean. In western Canada, persistent fires in northeastern British Columbia and central Alberta also produced substantial smoke, which drifted northeast into the southern Northwest Territories. The overall smoke field encompassed much of central and eastern Canada, with significant overlap of smoke layers leading to areas of enhanced concentration. The western edge of the smoke boundary hugged the eastern slopes of the Rockies, while the eastern edge extended far offshore into the North Atlantic. AEROSOL/SMOKE: Mexico/Gulf of America/Southern Texas/Pacific Ocean... An expansive 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 this evening extending over northern and southern Mexico, southern Texas, the Pacific Ocean off Mexico’s western and southern coastline, and the Bay of Campeche. This smoke and aerosol combination is likely over central Mexico but heavy cloud cover prevented further analysis in the region. Dust: Tropical Atlantic… Saharan Dust was seen extending westward from the African coast to the central Caribbean Sea, Hispaniola, and into the Central Atlantic. 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
