DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1500Z June 17, 2026
SMOKE: Northwest Territories… A large area of light-to-moderate density remnant smoke from previous fire activity was observed across northwestern Canada. Great Plains… A large area of light density remnant smoke was observed across southern Canada from eastern Alberta to south-central Ontario. Another large area of light-density remnant smoke was observed across the central U.S. from eastern Wyoming across the Midwest and off the Mid-Atlantic coast. Pacific Northwest… Scattered fires in Oregon, Washington, and Idaho produced light-to-moderate density smoke plumes drifting generally southeastward. Southwestern U.S… Isolated fires in southern Utah and Arizona were observed producing light-density smoke plumes drifting generally south or westward. A large area of light-density remnant smoke was observed extending southeastward into western Texas and northern Mexico. An area of moderate-density remnant smoke was observed northeast of Las Vegas centered around the Nevada-Arizona-Utah border. Florida… Wildfires in southern Florida, such as the Quarry 2(13) and Well (13) Fires, were observed producing individual light-to-heavy density smoke plumes extending northeast into the Atlantic Ocean. Western and southern Mexico/Pacific Ocean/Gulf of America… An area of light-density smoke consisting of remnant smoke from previous days and smoke from fire activity was observed in the Gulf of California, across the Isthmus of Tehuantepec, and extending northward into the western Gulf of America. The smoke also extended across southern Mexico, before drifting southwest into the Pacific Ocean. Monaghan 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
