DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1430Z September 11, 2025

SMOKE:
Western Canada/Pacific Northwest...
Wildfires persisted throughout western Canada and the northwestern
United States.
Localized moderate-heavy density smoke in southern British Columbia was
seen moving northeast across central Alberta, central Saskatchewan,
and northern Manitoba as it makes its way towards northern Manitoba
and the Hudson Bay. Light density smoke from the Canadian fires spread
throughout the rest of Canada extending east over western Ontario, and
continuing southeastward into the Midwestern United States, Southeastern
United States, eastern Texas, and the Northern Gulf of America.

California…
The Garnet fire in California remained active this morning. This fire
produced a small moderate-to-heavy smoke plume located near to the fire
source. A larger light density smoke plume was observed moving north
before dispersing east into central Nevada.

Southeastern United States…
Agricultural fires in the Southeastern United States contributed to the
large area of the light density smoke that was moving southeast from
the Canadian fires.

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.
