DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1500Z June 21, 2025
SMOKE: Alaska/Yukon/Canada/Northern and Central United States/Atlantic Ocean… Widespread wildfire activity across Alaska, the Yukon, and much of central Canada continued to generate expansive smoke coverage over large areas of the Northern Hemisphere. Thick density smoke was observed over interior Alaska and the northern Yukon, with plumes extending eastward and merging with other smoke layers over central Canada. A second area of moderate to thick smoke was present over central Saskatchewan, resulting from persistent fire activities in these regions. The smoke extended southeastward into the Great Lakes and Ohio Valley, while light smoke spread further east over the Mid-Atlantic and western Atlantic Ocean. In the central United States, light to moderate density smoke was seen originating from fires in northern Baja California, MX, Nevada, Utah, Arizona, and New Mexico This resulted in large areas of light smoke moving towards the NE eventually making it way over the Midwestern states. This area is the result of regional fire activity combined with transported smoke from the north and west. DUST: Saharan Dust…. An area of Saharan Dust was seen moving west towards the Lesser Antilles in the Caribbean. Rodriguez 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
