DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 2330Z July 21, 2025

SMOKE:
Alaska/Canada/Atlantic Ocean/Central and Northeast United States/...
Wildfires continued to burn in eastern Alaska/Yukon, the Northwest
Territories, northern British Columbia, and central Canada, with
widespread smoke observed across most of Canada and extending east towards
the Atlantic and south over the Great Lakes region and northeastern
United States. Higher density smoke was concentrated in much of central
Canada, specifically located over Alberta, central Saskatchewan, northern
Manitoba, and central Ontario.

Western U.S...
Wildfires were observed across the western U.S., from Washington State to
New Mexico. Smoke originating from the wildfire in northern California
was seen drifting eastward. Smoke from the wildfire in northern Arizona
was seen drifting towards the northeast. Cloud cover obscured further
smoke analysis in this region.

DUST:
Atlantic Ocean...
Saharan dust was observed blowing westward across the Atlantic Ocean,
drifting towards the Caribbean.

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.
