DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0120Z August 13, 2021
SMOKE:
Pacific off the West coast/Western and Central U.S./Great Lakes
region/Northeast/Mid-Atlantic region/Southeast/Southwestern Canada…
A very large mass of varying density smoke attributed to significant
wildfire activity in southern British Columbia of southwestern Canada and
the western U.S. was seen over southwestern Canada and much of the western
U.S. From the western U.S., the smoke extended to the east across the
Rockies and over the north central and central U.S. to the Great Lakes
region, the Ohio Valley, the Northeast, the Mid-Atlantic region, and the
Southeast. Thick smoke was seen over southern British Columbia, most of
Washington, northern Idaho, western Montana, and northern Oregon. Another
batch of thick smoke covered northwestern Nevada, western Oregon, the
northern half of California, and offshore of the southern Oregon/northern
California coast. Moderately dense smoke was present in areas across
the Rockies to the central U.S. Another patch of moderately dense smoke
was visible over a portion of the Mid-Atlantic region and Northeast and
offshore of those locations over the nearby Atlantic.
Eastern Canada and Western/Central Atlantic...
Generally thin density smoke from the Canadian and western U.S. wildfires
continued to spread across eastern Canada and off the coast across the
Labrador Sea and southern Greenland and well out over the Atlantic
south and southeast of Greenland. Cloud cover over portions of this
region interfered with smoke detection and density information from
satellite imagery.
Area from far Northwestern Canada to South Central Canada...A broad
area of smoke probably attributed to recent wildfire activity in
northwestern and western Canada and wildfire activity in Siberia that
was seen stretching from extreme eastern Russia through Alaska, central
Canada then to the south and southeast reaching the southern portions of
Saskatchewan and Manitoba and the southwest part of Ontario. While most
of the smoke appeared to be of thin density, the northern part over the
northern Northwest Territories was noticeably thicker.
DUST:
Puerto Rico/Eastern Caribbean...
Earlier today; A thin layer of Saharan dust shifted slightly farther to
the west and now was located in a north-south elongated band stretching
from the coast of northern South America across the eastern Caribbean
and Puerto Rico to around 30N latitude.

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
