DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0135Z July 19, 2021
SMOKE:
Northwestern Atlantic...
A detached light-density plume was detected approximately 150 miles off
the coast of Newfoundland. The plume can be seen stretching eastward
for +1,000 miles.
Alaska/Canada/CONUS...
Smoke can be seen across the majority of North America, with the
exception of western Alaska, southeastern U.S, Arizona and southern
California. A large area of moderate-to-heavy concentration smoke
dominates central-southern Canada and the northern U.S., and dipping into
the Great Plains past southwestern Nebraska. Numerous wildfires are seen
releasing thick smoke in northern California, southern Oregon, northern
Washington, southeastern British Columbia, northern Idaho and along the
Manitoba and Ontario southern border, with moderate smoke extending over
Montana, eastern Dakotas, Ontario and the Great Lakes area, and central
Quebec. Wildfires over the northwestern U.S. and British Columbia show
thick smoke plumes dispersing toward the northeast, whereas the larger
smoke plume covering northern U.S. and central-southern Canada is seen
traveling eastward. Another large area of light density smoke can be
seen over northern Canada, punctuated by a few thick plumes originating
from wildfires in the Northern Territories. The Bootleg Fire in southern
Oregon was actively burning this afternoon with heavy smoke blanketing
central-northern Lake County, in addition to southeastern Deschutes and
Crook counties. Finally, a light-density was observed over the western
Gulf of Alaska.
Southern Gulf of Mexico...
Light smoke originating from gas flaring activity in the Bay of Campeche
can be seen spreading for about 200 miles toward the northwest.
DUST:
Caribbean...
A light density plume of Saharan dust was detected over the Lesser
Antilles and eastern Caribbean.

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
