DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 2330Z June 21, 2026
SMOKE: Northwest Territories/Yukon/Alaska… Several fires in the Northwest Territories continued to burn today, producing moderate-to-heavy density smoke that spread through the central Northwest Territories. A lingering layer of light-density smoke spread in all directions across the region, traveling into Yukon and Nunavut. A separate light-density plume was also observed over central Alaska. Southwestern U.S/Central and Eastern U.S/Atlantic Ocean… The Iron fire, located south of Salt Lake City, produced localized heavy-density smoke, while medium-density smoke continued southward across Utah into Colorado. The Grapevine and Kane Springs fires in southeast Nevada produced localized heavy-to-moderate density smoke plumes. Lingering smoke from these fires, as well as scattered fires across the central U.S, contributed to a large layer of light smoke that stretched from eastern Nevada to central Nebraska. Northwestern and Southeastern Mexico/Central America/Pacific Ocean/Gulf of America… Individual plumes from fires in Veracruz and Tabasco produced localized medium-to-heavy density smoke. Another area of light-density remnant smoke from previous days, as well as smoke from industrial sources and fire activity, was observed over the Isthmus of Tehuantepec. The smoke dispersed into the Bay of Campeche, the central Gulf, the southern Yucatan Peninsula, parts of Central America, and southwards into the Pacific Ocean. Another area of light-density smoke was observed drifting from Northwestern Mexico across the southern Gulf of California, over Baja California Sur, and southwestward into the Pacific Ocean. Quebec… Two fires in western Quebec were observed producing light-to-medium density smoke drifting eastward, while a third, larger fire north of the Grande Riviere Reservoir produced localized light-to-heavy density smoke plumes. Dominican Republic… A large fire near the southwestern coast of the Dominican Republic was observed producing a plume of light-to-heavy smoke that drifted west over the Caribbean Sea, ultimately reaching Haiti’s Tiburon Peninsula. Ling/Marrs 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
