DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 2330Z September 21, 2025

SMOKE:
Northwest Territories/Central Canada/Southeastern United States…
Wildfires persisted throughout Canada in Alberta, Saskatchewan, and
southern Northwest Territories. Light-to-moderate density smoke from these
fires drifted north over Nunavut, east across Saskatchewan, Manitoba, and
into the Hudson Bay. Within this area of light smoke, moderate-to-heavy
density smoke produced by a wildfire in the south-central portion
of the Northwest Territories was observed drifting northeast toward
Nunavut. Additional light smoke from the Canadian wildfires continued
spreading south into the northern United States but was obscured by
clouds. The light smoke appeared to have extended southeastward through
the Southeastern United States, reaching the northern Gulf of America.

Washington State…
Fires continued across Washington State, producing moderate-to-heavy smoke
plumes which drifted east from Chelan County. Despite cloud cover over
the northern Rocky Mountains, light-to-moderate smoke appeared to have
extended northeastward over northern Montana and southern Saskatchewan,
mixing with surrounding plumes from Alberta, west-central Saskatchewan,
and the Northwest Territories.

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.
