DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 2330Z September 3, 2025

SMOKE:
Western Canada/Western United States...
Wildfires continued to burn across western Canada with the largest fires
and heavy smoke production in the Northwest Territories and British
Columbia. Due to heavy cloud cover, most of the smoke seen yesterday over
the Northwest Territories were obscure. There was a long, thick plume of
smoke from the fires in central British Columbia traveled southeast over
southern Alberta and Montana. Light to moderate density smoke covered
much of British Columbia, Alberta, and spread south over much of the
northwestern United States from the Pacific Coast to the Midwestern U.S.

US West Coast...
Wildfires in California, Oregon, and Washington State were observed
producing moderate to heavy density smoke plumes which moved to the
north and west. The largest plumes were observed in central California
and throughout Washington State. The smoke plumes from the wildfires in
Washington State, northern Idaho, and western Montana were also observed
merging with the light-to-heavy density smoke traveling southeast from
British Columbia.

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:

Unless otherwise indicated:
  • Areas of smoke are analyzed using GOES-EAST and GOES-WEST Visible satellite imagery.
  • Only a general description of areas of smoke or significant smoke plumes will be analyzed.
  • A quantitative assessment of the density/amount of particulate or the vertical distribution is not included.
  • Widespread cloudiness may prevent the detection of smoke even from significant fires.
