DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0000Z May 25, 2025
SMOKE: Northern Plains/Central and Northeastern Canada… Wildfires across far southeastern Manitoba and extreme southwestern Ontario were producing thick smoke that was seen moving southeast by the time sunset arrived. Smoke from earlier in the day could be seen as far south as the South Dakota-Nebraska border and extending off toward the west-northwest into south-central Canada. The smoke could, from there, be seen moving northward, where the smoke was moving over a larger area of wildfire activity across central Saskatchewan into northwestern Manitoba. This activity is adding thick smoke to the plume as it continues curving toward the Nunavut-NW Territory-Saskatchewan-Manitoba quadruple point then east-northeast over northern Manitoba, southern and eastern Nunavut, northern Hudson Bay, far northern Quebec, and over the Davis Strait. AEROSOL/SMOKE: Mexico/Central America/Western Caribbean/Tropical Eastern Pacific/Gulf of America/Gulf Coast/Southern Plains/North Atlantic… An area of light to moderate density smoke and aerosols - attributed to widespread seasonal fire activity throughout much of Mexico, Cuba, Hispaniola, and parts of the southeastern CONUS coupled with gas flaring in the Bay of Campeche and surrounding areas in the Mexican coastal plain and industrial sources throughout portions of Mexico was observed blanketing an area extending from Cuba and Hispaniola westward the Yucatan and Bay of Campeche, where moderate smoke was added to the layer as it moved northward into the southern Plains. From there, some smoke was drawn eastward along with from both active and remnant smoke from agricultural burning across the southeastern CONUS out over the northern Atlantic almost as far as Cape Race. Some of the emissions from the Pacific side of Mexico were also helping to create a light smoke layer across the tropical Eastern Pacific. Some contributions might be made from the gas flaring and burning along the Mexican coastal plain around the Bay of Campeche as well through the Isthmus of Tehuantepec. Hosley 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
