DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 2330Z September 23, 2026

SMOKE:
Canada…
A layer of light-density smoke from the fires in the Northwest Territories
and from fires throughout Canada drifted eastward across Nunavut,
Saskatchewan, Manitoba, the Hudson Bay, and off the coast of Baffin
Island before extending into Greenland. An area of moderate-density
smoke was observed from northern Manitoba extending east-northeastward
over the Hudson Bay.

Pacific Northwest…
Despite significant cloud cover, fires in north-central Washington and
southern British Columbia were observed producing a layer of light-density
smoke drifting northeastward before being obscured by clouds. An isolated
fire in Vancouver Island generated a light-to-moderate density smoke plume
drifting eastward towards Washington. The Sisi Fire was also observed
producing a light-to-moderate density smoke extending southeastward
within Washington.

California…
Moderate-to-heavy density smoke from the Dome Fire concentrated near the
source and drifted northward, while a regional layer of light-density
smoke persisted, extending southwestward across the state and into
the Pacific Ocean. An area of light-to-moderate density smoke from a
prescribed fire in Angel Island extended southeastward across the San
Francisco Bay and southwestward into the Pacific Ocean. The Crawford
Corral Rx Fire was also observed generating moderate-to-heavy density
smoke extending northwestward and northeastward.

Nevada…
A fire in southern Nevada was observed producing a light-to-heavy density
smoke plume extending northwestward.

Southeastern CONUS…
Several individual light-to-heavy density smoke plumes were observed in
Alabama, the Lower Mississippi Valley, Georgia, and Oklahoma drifting
westward or southwestward. A broad layer of light-density smoke spanned
the Southeastern United States, extending  northwestward into Kansas
before continuing offshore into the Gulf of America.

Mexico/Gulf of America…
A layer of light-density smoke from agricultural burning and industrial
activity were observed in the Gulf coastal region of Mexico, spanning
eastward into the Gulf of America and southward across the Isthmus of
Tehuantepec and into the Pacific Ocean. An area of moderate-density smoke
was observed in the Isthmus of Tehuantepec before extending northward
into the Gulf of America and southward into the Pacific. A separate
layer of light-to-moderate smoke drifted westward off the coasts of
Sinaloa and Nayarit into the Pacific Ocean.

BLOWING DUST:
Caribbean…
Blowing dust from the Sahara Desert was observed lofting over the Atlantic
Ocean towards the Lesser Antilles.

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

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.
