DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 2330Z October 4, 2026
SMOKE: Southeastern U.S./Atlantic Ocean… No significant areas of smoke could be seen via satellite imagery this evening due to cloud cover. Pacific Northwest… Fires in Washington, Oregon, and Idaho were observed producing individual smoke plumes that moved northward and northeastward. Most fires produced light-density smoke, while a fire in northern Idaho produced light-to-heavy density smoke. California Coast/Northwestern Baja California… A fire in northwestern Baja California was observed producing a light-to-heavy density smoke plume that drifted westward into the Pacific Ocean. 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. Mexico/Pacific Ocean… No significant areas of smoke could be seen via satellite imagery this evening due to cloud cover. Hernandez 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
