DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0000Z May 29, 2026
SMOKE: Canada/Midwestern CONUS… Active wildfire activity was observed across central Saskatchewan and the Northwest Territories-Alberta Border region producing thick smoke. From these fires, the smoke was observed moving east-northeast. A few other smaller fires from southern Manitoba into far northern Wisconsin were observed producing mainly light to moderate smoke, with perhaps heavy smoke also noted with one fire in northeastern Minnesota. In addition to the active emissions, remnant smoke was observed across much of the southern tier of Canadian Provinces and the Great Lakes states. Mid Atlantic/North Atlantic… An area of light remnant smoke was seen over the Mid-Atlantic extending eastward across the North Atlantic. The parent activity is likely the wildfire activity in Canada with some contribution from fire activity across the southeastern CONUS. Oregon/California/near-shore Pacific… An area of light smoke was observed swirling around a low pressure area just offshore of Monterey Bay. The smoke was light, with the leading edge having completely wrapped around the circulation. SMOKE/AEROSOL: Mexico/Pacific Ocean/Gulf of America/Central 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 Mexico and Central America. The smoke extended southwest into the Pacific Ocean, east into western Guatemala, and north across the west-central Gulf of America towards the southern United States. Individual fires in western Jalisco also produced an area of light-to-heavy density smoke, eventually mixing with the broader layer of light-density smoke. BLOWING DUST: West-Central Idaho… Blowing dust was observed through breaks in clouds very near Boise this afternoon. The dust was observed moving NNE into the more mountainous terrain across Boise National Forest. Caribbean… Saharan Dust was observed spanning the Atlantic and Caribbean. The thickest dust was seen extending westward from the African coast to near the Windward Islands. 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
