DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1430Z September 7, 2025

SMOKE:
Western Canada/Pacific Northwest...
Wildfires persisted throughout western Canada and the northwestern United
States. Heavy smoke was observed this morning moving east from British
Columbia, spreading across Alberta and drifting south into Montana. Fires
in the Northwest Territories and Washington State also emitted moderate
smoke and contributed to the eastern drift of smoke reaching Saskatchewan
and the Midwestern United States. Lighter smoke reached as far south as
the Gulf of Mexico and moved northeast along the Atlantic coast.

California…
Wildfires in central and northern California continued and produced
Moderate-to-heavy density smoke plumes. A larger plume in central
California drifted north into western Nevada. Heavier smoke spread into
a larger area of light density smoke which covered the northern half
of the state and mixed with smoke from the north as it moved east over
the Rockies.

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.
