DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0130Z August 28, 2021
SMOKE:
West Coast/Northern U.S./Southern Canada...
Widespread wildfire activity over parts of the Pacific Northwest, and
the northern half of California have resulted in a very large region
of light to heavy density smoke 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 and off the
Northeast coast. Clusters of wildfires over northern Saskatchewan and
Manitoba were cloud covered this morning but spreading moderate to heavy
density thin smoke plume eastward. Thick density smoke was observed
over most of Northern/Central California, Western/Southwestern Oregon,
South Central Washington, Northern/Western Nevada, Southeastern Idaho,
Southwestern Wyoming, Western/Northern Utah, and most of the North
Central U.S. Moderate to thick density smoke from Western U.S. wildfire
activity was also observed in Canada over Southern Nunavut, Manitoba,
Saskatchewan, and parts of the Central Hudson Bay in this evening’s
GOES visible satellite imagery.
Eastern U.S/Southern Canada/Western Atlantic Ocean...
A large region of light to moderate density smoke likely attributed to
Western U.S. widespread wildfire activity was observed over parts of
Southern Canada including Southern Quebec and Newfoundland. Smoke was
also observed over most of the Northeastern U.S including New England
and as well as parts of the Northern Mid Atlantic. Smoke was observed
as well over parts of the Western Atlantic south of Nova Scotia in this
evening’s GOES visible satellite imagery.
Southern Plains/Lower Mississippi Valley, Tennessee Valley...
A large region of light density smoke from both agricultural burning
activity and wildfires was detected across parts of the Southern Plains,
Lower Mississippi Valley, and Tennessee Valley. A discrete wildfire in
east-central Kansas was producing a long, narrow, thin to heavy density
plume that was spreading to the north over eastern Kansas. Light to
moderate density smoke was observed over most of the region this evening.
Pacific...
A region of light density smoke was observed earlier in the day covering
a large area just west of Baja California over the Eastern Pacific.
DUST:
Central and Eastern Caribbean Sea/Atlantic...
A large region of thick density Saharan dust was observed off the coast
of West Africa over the Eastern Atlantic. Light to moderate density
Saharan dust was also observed over parts of the Western Atlantic north
of the Lesser Antilles as well as over parts of the Central and Eastern
Caribbean Sea including the Lesser Antilles, Puerto Rico, and Hispaniola
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
