DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1430Z-15Z September 28, 2025

SMOKE:
Northwest Territories/Central Canada...
Wildfires continued to burn across northern and central Canada, with
smoke-producing activity observed across the Northwest Territories central
Alberta, and western Saskatchewan. Light smoke from these wildfires
moved east across the Northwest Territories and then curved south,
drifting across the Northern Plains and Upper Mississippi Valley/Midwest.

Pacific NW...
Wildfires also continued to burn across the Pacific Northwest, from
western Oregon and central Washington. Despite moderate cloud coverage
obscuring the full extent of the smoke plume, the heaviest smoke
was seen being produced by the wildfires in central Washington and SW
Oregon. Light-to-moderate smoke drifted northeastward across Washington,
northern Idaho, northern Montana, and eventually merging with the light
smoke from the Canadian fires.

Pacific Coast/Southwestern Oregon…
The Moon Complex fire in southwestern Oregon was producing
moderate-to-heavy smoke this morning. The thick smoke moved northeast
eventually mixing with the smoke from the Canadian fires and south along
the Pacific Coast. The smoke plume’s full extent was not visible due
to clouds along the southern Pacific Coast.

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.
