DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 2350Z May 4, 2025
SMOKE: South-Central Canada / North-Central U.S... A large and coherent region of light to medium density smoke was observed extending from central Saskatchewan and Manitoba into eastern North Dakota, Minnesota, and down through Iowa and northern Missouri. This smoke is attributed to ongoing fire activity in western Canada and the northern Rockies. Embedded pockets of medium-density smoke were most prominent over southern Manitoba and northeastern South Dakota. Southern Plains... Scattered plumes of light smoke with isolated areas of medium density were seen across eastern Kansas, northern Oklahoma, and parts of western Arkansas. This smoke is remnant from regional fire activity and drifted slightly southeastward during the afternoon hours. Northern-Central-Western Mexico... A compact but concentrated area of light to medium smoke was observed across northern and western Mexico, including the states of Sonora, Durango, and parts of Sinaloa. This region continues to experience intense seasonal burning, with medium density smoke confined to the areas of heaviest fire activity. AEROSOL/SMOKE: Central and Southern Mexico/Gulf of America/Southern Texas/Bay of Campeche/Pacific Ocean... An area of light density smoke/aerosol attributed to widespread seasonal fire activity, volcanic emissions, and industrial sources throughout Central and Southern Mexico was observed today over the coastline of Southern Mexico. The combination continued to extend west into the Pacific Ocean off the coast of southwestern Mexico and Central America. The combination of smoke and aerosols progressed northward along the eastern coastline of Mexico into southern Texas and east into the Gulf of America. 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 map: https://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
