DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0200Z September 2, 2021

SMOKE:
Western and Northwestern U.S./Rocky Mountains/Great Plains/Northeastern
CONUS/Central Canada/Pacific/Gulf of Mexico...
Widespread wildfire activity throughout the Western CONUS was observed
emitting moderate to thick density smoke. Smoke from wildfire activity
in Western Oregon was moving south-southwestward, while most smoke
from Northern California wildfire activity including the Dixie and
Caldor wildfire complexes was observed moving northeast towards
and over Nevada. Smoke from Northwestern California wildfires was
observed progressing out over the Pacific and southward towards San
Francisco. Moderate to thick density smoke was moving east-northeast out
across the Great Basin and Intermountain West then northward into Central
Canada. Moderate to thick density smoke was also observed progressing
southeastward over the Northern,Central, and part of the Southern Plains,
as well as over the Mid Mississippi Valley. Light to moderate density
smoke was observed over the southeastern U.S. as well as parts of the
North Gulf of Mexico and over most of Texas. Smoke from wildfire activity
in East-Central Saskatchewan and Central Manitoba was observed moving
through Canada, however cloud cover from a weather system in the area
made the smoke analysis difficult in this region. Thick smoke was also
observed from wildfire activity in the Northwestern U.S. including fire
activity in Idaho and Washington. Thick density smoke continues to be
observed from Western U.S. wildfire activity progressing over a large
region of the CONUS this evening.

South Texas/Southern and Eastern Mexico/Southwestern/Western Gulf of
Mexico...
Light to moderate density smoke from offshore drilling platforms was
observed over coastal South Texas earlier today. Light to moderate
density smoke continues to be observed over parts of the Southwestern
and Western Gulf of Mexico as well as over parts of coastal Southern
and Eastern Mexico this evening.

DUST:
Tropical and Western Atlantic/Western Caribbean/Gulf of Mexico/South
Florida...
A large region of light to moderate density Saharan dust was observed
over parts of the Western Caribbean Sea to the south of Cuba as well as
over parts of the Southern Gulf of Mexico. Light to moderate density
Saharan dust was also observed over parts of South Florida as well as
over parts of the Western Atlantic offshore from the Southeastern U.S. A
large region of light to moderate density Saharan dust was also observed
over the Eastern/Central Tropical Atlantic to the north of Tropical
Storm Larry in this evening’s GOES visible satellite imagery.

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.
