THROUGH 2330Z September 30, 2026
SMOKE: Southeastern U.S./Mississippi Valley... Numerous fires across the southeastern U.S. and Mississippi Valley were observed producing light-to-moderate density smoke plumes drifting generally westward to northward. Isolated fires in Louisiana, Alabama, and Georgia were observed producing heavy smoke. Oregon... Fires across the state of Oregon were observed producing light-to-heavy density smoke drifting southeastward within the state. California... The Dome Fire in Yosemite National Park continued to burn this evening, producing light-to-heavy density smoke that initially moved west-northwest before shifting southward within the state. Mexico/Gulf of America... A layer of light-to-moderate density smoke from agricultural burning and industrial activity was observed across the western Gulf of America and along the Mexican Gulf coast, extending southward across the Isthmus of Tehuantepec. YL 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
