DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1430Z September 18, 2025

SMOKE:
Canada, Southeastern and Northeastern United States..
Wildfires continued to burn across Canada and western United
States. Moderate-to-heavy smoke from fires in north-central Alberta and
the southern region of the Northern Territories was observed dispersing
further north into Nunavut. A large light smoke plume from these fires
extends from the Northwest Territories through Alberta, and Saskatchewan,
and is observed reaching south into the southeastern United States and
east towards the northeastern United States. While fires in western
Canada remain active, their scale is significantly less than what was
observed in previous weeks.

Washington State…
An area of light-to-moderate density smoke extended north from the
large wildfire over the Olympic Peninsula in Washington, merging into
the smoke plumes observed in southern and eastern British Columbia and
northern 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.
