DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1430Z September 20, 2025

SMOKE:
Southwest Canada/Central Canada/Southeastern United States…
Wildfires persisted throughout Canada in southern British Columbia,
Alberta, and southern Northwest Territories. Moderate-to-heavy smoke
drifted east from the western fires over southern Nunavut and northern
Manitoba where it curved south towards the Dakotas and Great Lakes region
but was obscured by clouds. Light smoke appeared to continue spread
into the southeastern United States, from Texas to the Mid Atlantic,
with some additional light smoke from agricultural burns in the region.

Washington State…
Fires continued across Washington State, producing moderate-to-heavy
plumes which drifted east from the Olympic Peninsula and eastern
Cascades. Moderate-to-light smoke spread across eastern Washington,
northern Idaho and Montana, with some movement north to mix with smoke
from fires in British Columbia and Alberta.

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.
