DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 2350Z May 6th, 2025
SMOKE: Western and Central Canada / Upper Midwest U.S.: A large area of light to medium density smoke extended from central Alberta and Saskatchewan through southern Manitoba into parts of the northern United States, including North Dakota, Minnesota, and Wisconsin. Medium density smoke cores were concentrated in southeastern Alberta and southern Saskatchewan, with the plume drifting east-southeast through the day. Pacific Northwest: Active wildfires in northwestern Oregon near Portland produced medium density smoke, pushing eastward into western valleys and foothills. Additional light to medium smoke was observed across parts of southern Oregon and far northern California. Southeastern U.S.: Multiple small plumes of light smoke were detected across Florida, southern Georgia, and South Carolina. These originated from agricultural or prescribed burns and drifted slowly northeast toward the Atlantic Ocean. Mexico / Yucatán Peninsula / Southern Gulf: A large, persistent area of light to medium density smoke covered much of southern Mexico, including the Yucatán Peninsula, Veracruz, and Oaxaca. Numerous fires contributed to this mass, which expanded into the Bay of Campeche, Gulf of America, and adjacent Pacific coastal waters. AEROSOL/SMOKE: Southern Mexico / Bay of Campeche / Gulf of America / Pacific Ocean: An expansive area of smoke and aerosols persisted over southern Mexico due to ongoing fire activity, volcanic emissions, and industrial sources. The plume extended across the Yucatán Peninsula and into the southern Gulf of America. A secondary branch of the aerosol/smoke layer extended southwestward over the Pacific, affecting coastal Oaxaca and Guerrero. Cardona 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
