DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 2350Z July 4, 2025
SMOKE: Alaska/Canada… Fires across central Alaska, northern British Columbia, Saskatchewan, and Manitoba remain active, continuing to emit thick to moderate smoke. Compared to the morning, smoke over the central Canadian provinces has expanded eastward and thickened, with moderate to heavy plumes more consolidated over Manitoba and Ontario. The Alaskan smoke still drift west. Central/Eastern US… Merged plumes from Canadian and southwestern U.S. sources have intensified. A broad zone of light to moderate smoke now spans from the central Plains through the Midwest to the Northeast, with pockets of heavier smoke in the Upper Midwest and western Great Lakes. Southwestern US… The Madre fire in southern California persists. Light smoke continues eastward over the Rockies, feeding into the central U.S. plume. Atlantic… Light smoke still pushes off the East Coast into the Atlantic, showing continued transport from the continental fires. Cardona 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
