DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 2330Z October 21, 2025
SMOKE: U.S. Southeast… Despite heavy cloud cover obscuring a portion of the Southeastern United States, an area of light smoke was observed this evening in the region and is moving east with an incoming cold front. The plume consists of light density smoke produced by the agricultural fires throughout the region. The area of smoke may also include remnants of smoke from yesterday’s agricultural burning in the region. U.S. West Coast… Individual fires stretching from Washington State to Northern California were observed producing areas of light density smoke throughout the region. Fires on the coast of Oregon and Washington State produced light-to-moderate smoke plumes that drifted offshore in the Pacific Ocean. In the northern Central Valley of California, an area of light density smoke produced by agricultural fires in the region remained in close vicinity to the fire sources. In northern Idaho, many individual fires produced an area of light density smoke that extended northeastward towards western Montana. AEROSOL/SMOKE: Mexico/Gulf of America... An area of light density smoke, consisting of aerosols from industrial activity in central Mexico and smoke emissions from individual fire activities in the region, was observed spreading from southern Mexico to Texas’ Gulf Coast and dispersing offshore in the central Gulf. Additional light smoke was also observed along Mexico’s Pacific coast, dispersing offshore in the Pacific Ocean. GL 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:http://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
