DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 2330Z August 24, 2025

SMOKE:
Northern Canada...
Wildfires in the Northwest Territories continued to emit moderate density
smoke which spread to a light layer of smoke from western Northwest
Territories to Nunavut and the Arctic.

Nova Scotia...
A large, dense plume of smoke was observed billowing from the Long Lake
Wildfire in western Nova Scotia. The plume spread to the northeast into
the Gulf of St. Lawrence.

Western United States/Southeastern United States...
Wildfires in the western United States continued to release
moderate-to-thick plumes of smoke, with the heaviest smoke observed in
central California, central Oregon, the Olympic Peninsula, central Idaho
and western Montana. The smoke spread into a light layer which covered
the west coast to the south and circulated to the east from Washington
into Montana and Wyoming. The smoke thinned and drifted across the central
United States and into the southeast, where proscribed burns contributed
to the layer of smoke as it continued northeast along Appalachia before
turning to the east and moving offshore just north of the Nova Scotia
plume.

DUST:
Saharan Dust was seen observed circulating in the eastern Caribbean and
central Atlantic, moving to the northeast over Puerto Rico.

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.
