DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1430Z August 17, 2025

SMOKE:
Canada/Western CONUS...
Heavy cloud cover obscured smoke detection over the wildfires located
across the Northwest Territories. Wildfires in western Montana, central
Wyoming, and northern Nevada remained active, producing light-to-heavy
smoke blanketing much of the northern Great Plains. Moderate-to-heavy
smoke were concentrated in eastern Montana, eastern Wyoming, western
Nebraska, and southwestern South Dakota as the smoke continues to
disperse eastward.

Midwestern CONUS/Nova Scotia/Atlantic Ocean...
Light smoke was observed persisting east across the Great Lakes region
and the Mid-Atlantic states and then travel northeast along the coast
of New England. It continues to travel over New Brunswick, Nova Scotia,
Newfoundland, and Labrador until it reaches the Labrador Sea. A large
wildfire in Nova Scotia was seen producing moderate-to-heavy smoke that
travels northeast and eventually merges with the light smoke traveling
towards the Labrador Sea.

DUST:
Caribbean...
Light-to-moderate dust from the Saharan Desert was observed alongside
Hurricane Erin over the Atlantic Ocean and in close proximity to the
Caribbean Islands.

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.
