DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 2330Z May 25, 2026
SMOKE: Montana… Light-density smoke was observed in Montana moving northeast toward Canada from a fire in Chouteau County. Canada… Fires were observed in southern Saskatchewan and Manitoba producing a light-density smoke plume that moved southeast into the northern United States. A fire in central Manitoba was also observed producing moderate-to-light-density smoke, which moved southeast within the province. 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 Central America, and north across the western Gulf of America into the southern United States. Portions of moderate-density smoke were also observed extending from the southern Gulf of America across the Isthmus of Tehuantepec and southwest into the Pacific Ocean. Many fires, including several large fires in Jalisco, Colima, Nayarit, and Michoacán, produced heavy-to-moderate density smoke that moved southeast and then south throughout the evening. This smoke later transitioned to, and contributed to, the broader area of light-density smoke observed across the region. Hernandez 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
