DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0250Z August 23, 2021
SMOKE:
U.S./Canada/Pacific...
Large wildfires in the western U.S. and southwestern Canada continued to
burn today and were responsible for a large area of smoke seen across
significant portions of the U.S. and Canada as well as off the U.S. West
Coast. Dense smoke primarily from the wildfires in the western U.S.
stretched eastward across sections from central/northern California into
most of Nevada into southeast Idaho, most of Utah, and across most of
Wyoming and northeast Colorado. The most dense areas of smoke extended
across northern Utah and into western and central sections of Wyoming,
central Oregon, northern California, and northwestern Nevada. Lighter
density smoke extended across most of the Pacific Northwest and eastward
across the Northern and Central Plains and reaching into Wisconsin and
well into Iowa. Smoke stretches northward into southern Alberta and
British Columbia, central Saskatchewan, and central/southern Manitoba,
and western Ontario. Smoke also stretches southwestward off the southern
California coast with a thickness difficult to confirm due to clouds.
Light to moderate density smoke stretches from the Mid-Atlantic/Ohio
Valley northward across the eastern sections of the Great Lakes and
across southern Ontario into central Quebec.
Alaska/Canada...
Thin density smoke was seen spreading to the east and across northern
part of Canada from the Northwest Territories to Labrador and
Newfoundland. Smoke was most likely sourced from fires burning in
Siberia a few days ago.
DUST:
Atlantic...
A very large plume of light to moderate density Saharan dust was detected
covering all of the western Atlantic and Caribbean Sea.

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
