DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1603Z August 27, 2021

SMOKE:
West Coast/Northern U.S./Southern Canada...
Ongoing large wildfires over southwestern Canada, the Pacific Northwest,
and the northern half of California have resulted in a very large light
to heavy density plume over the West Coast, the Great Basin, and
extending eastward either side of the U.S./Canadian border north to
south for several hundred miles to the open Atlantic off the Northeast
coast. Clusters of wildfires over northern Saskatchewan and Manitoba
were cloud covered this morning but a spreading moderate to heavy density
thin smoke plume eastward. The thickest smoke was found over the
northern half of California and western Nevada.

Southern Plains/Lower Mississippi Valley, Tennessee Valley...
A large thin density plume from both agricultural burns and wildfires
was detected across this region.  A discrete wildfire over north-central
Oklahoma was producing a long, narrow, thin to heavy density plume that
was spreading to the north over eastern Kansas.

Pacific...
A thin density plume covered a large area just west of Baja California.


DUST:
Atlantic...
A thin plume of Saharan dust was detected over the central 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
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.
