DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 2330Z October 3, 2026
SMOKE: Western U.S.… The Dome and Piute Fires in central California were observed producing localized heavy-to-moderate density smoke plumes, as well as a layer of light-density smoke that drifted northward and westward within the state. A fire north of Los Angeles was observed producing a plume of light-to-heavy density smoke that drifted westward. Multiple fires spanning northern California, Oregon, Washington, Idaho, and western Montana were observed producing localized light-to-heavy density smoke plumes that drifted generally northward. A remnant layer of light-density smoke was observed drifting southwestward over the Pacific Ocean offshore of southern California and western Mexico. Southeastern U.S./Atlantic Ocean… A layer of remnant light-density smoke was observed spanning the coast of the southeastern United States this evening, before drifting northeastward into the Atlantic Ocean. Mexico/Pacific Ocean… Multiple fires in northern Baja California were observed producing light-to-heavy density smoke that drifted westward. A fire in western Sonora was observed producing light-to-moderate smoke that drifted westward into the Bay of California. A remnant layer of moderate-density smoke from yesterday’s agricultural burning and industrial activity was observed over the Isthmus of Tehuantepec and the Bay of Campeche this evening. Remnant light-density smoke from the same sources was observed spanning the Gulf of America and the Pacific coast of Oaxaca. Marrs 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
