DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 2330Z October 5, 2026
SMOKE: Pacific Northwest/Northern Plains... Scattered fires in Washington, Oregon, Idaho, and northwestern Montana were observed producing individual light-density smoke plumes that drifted generally eastward. Multiple fires located in Idaho and Montana produced localized heavy-density smoke. These individual plumes contributed to a broad layer of light-density smoke that stretched from central Oregon across the northern Rockies and towards the northern Plains. California... Multiple fires in northern California produced light-to-heavy density smoke this evening that extended across the region, contributing to a broad layer of light density smoke that continued into southern Oregon and offshore into the Pacific Ocean. The Dome Fire in Yosemite National Park continued to burn this morning, producing light-to-moderate density smoke drifting northwestward. Mississippi Valley… Widespread agricultural fires were observed across the middle and lower Mississippi Valley today, producing light-to-heavy density plumes that traveled southwestward. These plumes contributed to a broad regional layer of light-density smoke. California Coast/Northwestern Baja California... A fire in northwestern Baja California continued to produce a light-to-moderate density smoke plume this evening. A large plume consisting of lingering smoke from this fire drifted southwestward into the Pacific Ocean, as well as northwards into southern California. A broader area of light-density smoke was observed extending from northwestern Baja California along the coast of west-central California and offshore into the Pacific Ocean. A separate layer of medium-density smoke was observed just offshore of Baja California Sur, which merged with the regional layer of light-density smoke over the Pacific Ocean. Cuba… Light-to-moderate smoke plumes were observed emanating from industrial sources in west-central Cuba today, traveling northwestward across the Straits of Florida. Gaskill 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
