DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0200Z August 10, 2021

SMOKE:
Canada and the United States...
A large region of thick density smoke attributed from the Dixie
wildfire complex and several other large wildfire complexes in Northern
California was observed over Northern California as well as to the
west offshore over the Pacific Ocean. Thick density smoke was seen
progressing northward, westward, and eastward from the large complex
fire activity and has resulted in broad region of thick density smoke
being observed over Southern Oregon, Northern/Central Nevada, Southern
Idaho, Northern/Central Utah, Northern Colorado, Wyoming, Montana,
and over a large region of the North Central and Central U.S. Wildfire
activity was also observed over parts of central, south central, and
southwestern Canada, along with the northwestern U.S. Smoke continues to
be observed covering a broad region extending from the Pacific Northwest
into and across almost all of Southern/Central Canada, where the fire
activity in east-central Manitoba and western Ontario adds to the region
of smoke. Light to moderate density smoke covers the NW US, much of
Canada and the high plains of the US as well as over the Midwestern
US, Mississippi valley, Great Lakes and continues east across the Ohio
Valley, southeastern US, and mid-Atlantic region where it exited into
the western Atlantic. Medium density smoke covered most of the northern
U.S. and southern Canada. A very large amount of thick density smoke was
also observed from northwestern U.S. and extended to the east over the
central U.S. and southern Canada in this evening’s satellite imagery.

Eastern Canada/Western Atlantic Ocean...
Large regions of light to moderate density smoke likely attributed from
Western U.S. wildfire activity was observed over parts of Eastern Canada
and the Western Atlantic in this evening’s GOES visible satellite
imagery.

Southern Mexico/Bay of Campeche...
Light to moderate density smoke was observed over parts of Southern
Veracruz and parts of Tabasco.  Light to moderate density smoke was
also observed from offshore drilling platforms over parts of the Bay
of Campeche.

DUST:
Puerto Rico/Eastern and Southeastern Caribbean/Central and Eastern
Atlantic...
A thin layer of Saharan dust was visible over the central and eastern
portions of the Caribbean Sea and continued to move to the west earlier
today. Saharan dust was observed as well over parts of the Eastern and
Central Tropical Atlantic 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.
