DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 2330Z July 31, 2025

SMOKE:
Alaska/Canada/North Atlantic Ocean...
A large area of smoke persisted across the northern region of the
continent, and drifted towards the east from the Northwest Territories to
the North Atlantic. Wildfires in the Northwest Territories, Saskatchewan,
and Manitoba continued to produce large, dense plumes of smoke that
moved east across Ontario and Quebec, thinning toward the Atlantic. The
highest concentration of smoke plumes were observed over Saskatchewan,
Manitoba, and western Ontario, with a southeast trajectory.

Arizona/Utah/Central United States...
The Monroe Canyon fire in central Utah and the Dragon Bravo fire in
northern Arizona continue to burn, emitting light-to-moderate smoke in
the region and merging with the larger area of smoke produced by the
Canadian wildfires as the smoke drifted northeast.

DUST:
Tropical Atlantic Ocean and Caribbean Sea...
Light Saharan dust was observed over parts of the tropical Atlantic Ocean,
expanding west over 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
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.
