DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1630Z July 24, 2021
SMOKE:
Canada, United States, and Western Atlantic Ocean...
Widespread wildfire activity over parts of Southern Canada and the Western
U.S. were responsible for a broad region of light to moderate density
smoke observed over most of the Mississippi and Ohio River Valleys as
well as over most of the Southeast U.S. expect South Florida, also over
the coastal Mid Atlantic including the Carolinas, Virginia, and parts
of Maryland. Light density smoke was also observed over parts of New
England and parts of the Western Atlantic south of Newfoundland. Moderate
density smoke was observed over the Southeast U.S as well as over the
Mississippi Valley. Moderate density smoke was seen covering all of
the Northern Rockies and North Central U.S. Thick density smoke was
seen close to and away from large complex wildfire activity in Southern
British Columbia, Northern Washington, Northern Idaho , Western Montana,
Southern Oregon, and Northern California. Thick density smoke was also
observed over Southern Alberta, Southern Saskatchewan, Northern Montana,
Northern Nevada, Western North Dakota, and Northern South Dakota as
well as over parts of the Central U.S including Wyoming, Nebraska, and
Iowa. Thick density smoke was also observed over Southern Manitoba,
most of Western/Northern Ontario, and Northern Quebec from wildfire
activity observed in this morning’s GOES visible satellite imagery.
Northern Alaska and Northwestern Canada...
A large region of moderate to thick density smoke was observed over the
Northern Yukon attributed from wildfire activity in the region. Light to
moderate density smoke was observed as well over most of Northern Alaska,
Southern Yukon, and the Northern Northwest Territories attributed from
smoke transport from wildfires in parts of the region observed in this
morning’s GOES visible satellite imagery.
DUST:
Gulf of Mexico, South Texas, Southern Mexico, Northern Central America,
Caribbean Sea, Central and Western Atlantic Ocean...
A broad region of light to moderate density Saharan dust was observed
over most of the Central Tropical Atlantic extending westward to over
parts of the Western Atlantic. Saharan dust was observed as well over the
Eastern and Central Caribbean including over the Southeastern Bahamas,
Hispaniola, Puerto Rico, and the Lesser Antilles. Saharan dust was also
observed over the Western Gulf of Mexico as well as over Southern Texas,
Eastern/Southern Mexico including the Yucatan Peninsula, and parts of
Northern Central America in this morning’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
