DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 2330Z August 23, 2025
SMOKE: Canada... Wildfires remained active in central and southern Northwest Territories, producing moderate to heavy density smoke closer to the source and light density smoke covered much of northern Canada and extended east towards Nunavut. Nova Scotia… The Long Lake Wildfire in eastern Nova Scotia was actively producing moderate to heavy density smoke plume which emitted towards the NE remaining mostly within Nova Scotia. Western CONUS/Central CONUS/South Central Canada... Wildfires in the western United States remained active, including the Flat fire in central Oregon, the Pickett Fire in northern California, northern Nevada, central Idaho, western Montana, western Wyoming and western Colorado. Smoke with the heaviest density were concentrated in central Idaho and western Colorado. Mostly light to moderate density smoke in this area dispersed east, dips southeast near the Central Plains, continued moving NE towards the Great Lakes, and making its way south over the Mississippi Valley and southeast Texas. Lower Mississippi Valley… Various agricultural fires were seen throughout the lower portion of the Mississippi Valley. The light density smoke plumes seen emitting from these fires were moving south eventually mixing with the smoke from the wildfires coming from the western CONUS. Blowing Dust… Blowing dust was seen in the Southwest CONUS, specifically in Arizona and southern California. 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
