DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 2330Z September 25, 2026
SMOKE: Canada… Two wildfires in the Northwest Territories were observed producing light-to-heavy density smoke generally remaining in the vicinity of the fire. An area of remnant light density smoke was observed southwest of Hudson Bay. California… The Dome Fire was observed producing light-to-density smoke drifting northeastward. Fires in north-central California were observed producing light-density smoke drifting northward. Western U.S… Isolated fires in western Montana and northern Utah were observed producing light-to-moderate density smoke drifting northeastward. Southeastern U.S.… Many agricultural fires across the southeastern U.S. were observed producing numerous smoke light-to-moderate density smoke plumes drifting generally southwestward. Significant activity in eastern Arkansas and southeastern Missouri produced moderate-to-heavy density smoke plumes. Mexico/Pacific Ocean/Gulf of America… Remnant layers of light-density smoke from agricultural burning and industrial activity was observed from the U.S. gulf coast southward into the Isthmus of Tehuantepec and along the western coast of Mexico and into the Pacific Ocean. Remnant areas of moderate-density smoke were observed in the Isthmus of Tehuantepec and south-southeast of Baja California. 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
