DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 2330Z September 29, 2026
SMOKE: Southeastern U.S./Mississippi Valley… Many fires across the southeastern U.S. were observed producing light-to-moderate density smoke plumes drifting generally westward to northward. Isolated fires in South Carolina and Alabama, in addition to fires in the Mississippi Valley were observed producing heavy smoke plumes. A remnant layer of smoke was observed across the Southeastern U.S. from previous days’ agricultural burning. Oregon… Numerous fires across the state of Oregon were observed producing light-to-heavy density smoke drifting east to southeastward. Western U.S.… Isolated fires in California, Montana, Nevada, and Idaho were observed producing light-to-heavy density smoke plumes. Mexico/Gulf of America/Baja California Sur/Pacific Ocean… A layer of light-density smoke from agricultural burning and industrial activity was observed across most of the Gulf of America, continuing southwards across the Mexican Gulf coast and crossing the Isthmus of Tehuantepec. A large layer of medium-density smoke stretched northwards over the Isthmus of Tehuantepec, continuing through the Bay of Campeche and reaching southern Texas. A remnant layer of light-density smoke was observed drifting over the Pacific Coast of Mexico, the Gulf of California, and Baja California Sur before continuing into the Pacific Ocean. Monaghan 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
