DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1420Z August 4, 2025

SMOKE:
Alaska/Canada/Great Lakes...
Widespread light smoke persisted across the northern region of
the continent as it circulated to the east, reaching the Atlantic
Ocean. Wildfires in the Northwest Territories, Saskatchewan, and Manitoba
continued to produce dense smoke plumes which spread into large areas
of moderate-to-heavy smoke and moved east across Ontario and Quebec,
with the high density smoke thinning over southern Quebec and the medium
density smoke extending as far east as the Atlantic before thinning
out. As the smoke travels east, it also extends over the Great Lakes
region and northeastern United States.

Arizona/Utah/Central United States...
The Monroe Canyon fire in central Utah and the Dragon Bravo fire
in northern Arizona continued to produce light-to-heavy smoke
plumes. Moderate-to-heavy smoke plumes were concentrated in northern
Arizona, Utah, Colorado, New Mexico, northern Texas and western Kansas
with light density smoke extending south over Texas and northern Mexico.

California…
The Gifford Fire in southern California produced a large,
moderate-to-heavy density smoke plume that drifted south over the
western Channel Islands, extending south towards the Pacific coast of
Baja California and northeast over northern Nevada.

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.
