DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 2330Z August 22, 2025
SMOKE: Canada... Fires in the Northwest Territories continued to generate a large area of light smoke which persisted over much of central Canada, with some spread to the east over Nunavut. Northern California/Oregon… Fires in northern California and central Oregon remained active, and generated moderate-to-thick plumes of smoke which drifted west towards the Pacific. The plumes spread into a larger area of light smoke covering northern California, western Oregon, and southwest Washington. Western United States and Rocky Mountains ... Fires continued in northern Nevada, Idaho, western Montana and Wyoming which generated a large area of light smoke that extended from Idaho to Minnesota. Thick plumes of smoke were seen moving east from the fires in in Idaho, Montana, and Wyoming. The largest and thickest plume grew from fires in western Wyoming and reached central South Dakota. Moderate smoke concentrated around the fires in the northern panhandle of Idaho. Mills 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
