DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1500Z May 3rd, 2025
SMOKE: Northwestern United States/British Columbia... A thin and elongated layer of smoke likely associated with long-range transport from wildfires in Asia was observed this morning approaching the coastline of Northern California, Oregon and Washington states, and extending into Southeastern and Central British Columbia. Southern Canada/US Midwest... A area of light remnant smoke from previous day fires in Washington, Oregon, Idaho, Montana and Northern Alberta could be seen moving eastward over Eastern Alberta, Central Saskatchewan, Southern Manitoba, and extending to the south into the Eastern Dakotas, Western Minnesota and Iowa, and Eastern Nebraska and Kansas. Southern New Mexico/Central-Southern Texas/Northern-Central Mexico... A large area of light smoke extended from Central Mexico to Texas and Southern New Mexico as a result of widespread fire activity across most of Mexico. The smoke was particularly concentrated over the state of Veracruz in Central Mexico, overlapping with another large area of mixed aerosols and smoke described below. AEROSOL/SMOKE: Central and Southern Mexico/Gulf of America/Bay of Campeche/Pacific Ocean... An area of light density smoke/aerosol attributed to widespread seasonal fire activity, volcanic emissions, and industrial sources throughout Central and Southern Mexico was observed today over the coastline of Southern Mexico. The combination continued to extend west into the Pacific Ocean off the coast of southwestern Mexico and Central America. The combination of smoke and aerosols progressed northward along the eastern coastline of Mexico into southern Texas and east into the Gulf of America. WS 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
