DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1430Z September 23, 2025

SMOKE:
Northwest Territories/Central Canada/Southeastern United States…
Wildfires persisted throughout Canada in British Columbia,
Alberta, Saskatchewan, southern Northwest Territories, and southern
Manitoba. Moderate-to-heavy density smoke from fires in the southern
Northwest Territories was observed drifting east and north into Nunavut. A
wildfire in northeastern Alberta also produced moderate-to-heavy smoke
that moved north into the Northwest Territories. These fires collectively
produced additional areas of light smoke that spread across Nunavut,
southern Manitoba, western Ontario, and into the Hudson Bay, with plumes
extending farther north beyond Nunavut. Light smoke also extended south
into the Northern Plains and Midwest before moving further south and east,
eventually reaching the southeastern United States.

Washington State…
Fires continued across Washington State, with those in Chelan County and
Kittitas County producing moderate-to-heavy smoke plumes that dispersed
locally before moving northward into British Columbia. Lighter smoke
from these fires, along with those in Olympic National Forest, merged
and spread across much of the state.

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:

ANY QUESTIONS OR COMMENTS REGARDING THIS PRODUCT SHOULD BE SENT TO:

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.
