DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0000Z October 1, 2025

SMOKE:
Northwest Territories/Central Canada/Southeastern CONUS…
Scattered wildfire activity continues to be analyzed across the
southern Northwest Territories, northern Alberta, and west-central
Saskatchewan. Considerable cloudiness was present across nearly the
entirety of Alberta, northern and far western Saskatchewan, and far
southeastern Northwest Territories. As such, the smoke in those areas is
inferred from any small breaks and smoke more clearly observed outside
the cloud canopy. Also as a result of the cloud cover, Smoke analysis
from a majority of the wildfires is very difficult due to the cloud
cover, with only the wildfire in south-central Northwest Territories
not obscured by cloud cover.
Outside of the thick cloud cover, mainly light smoke is seen moving
with the clouds south of the clouds over northern Manitoba. Remnant
smoke is also observed across central North America, extending from
Texas to Manitoba and Saskatchewan. This area of smoke is merging with
the smoke layer from the wildfires across northern Saskatchewan and
Manitoba. The source of this light smoke layer is likely scattered to
widespread agricultural burning across the southern Prairie Provinces, the
southern Plains, Mississippi Valley, and southeastern CONUS. The active
smoke plumes from today’s burning were observed moving southwestward
across the Mississippi Valley and Southeast CONUS today, while smoke
across the Plains was moving North.

Washington State/British Columbia…
Wildfires continue to burn across central Washington State. The light to
moderate smoke produced from these wildfires was seen moving northeastward
then northward. Due to cloud cover in the area, determining full extent
and smoke density is hampered. This also lends to uncertainty as to
whether or not the smoke is currently connected to the larger area of
smoke described above. Breaks in the clouds near the BC/AB border hint
at a lack of smoke making it much into Alberta.

Southern California/Pacific…
Light to perhaps moderate remnant smoke was observed again this afternoon
across the coast of southern California extending south and southwestward
to the northern periphery of the remnants of Narda in the Pacific. This
is likely the result of remnant smoke from fires in the Pacific Northwest,
mainly a wildfire in extreme southwestern Oregon.


BLOWING DUST:
Central Arizona…
Some light blowing dust was observed moving northeastward over the
Phoenix Metro Area this afternoon.

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.
