DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1700Z September 4, 2021
SMOKE:
CONUS/Pacific off the U.S. West Coast/Atlantic off the U.S. and Canada
East Coast/Northern Gulf of Mexico/Southwestern, South Central, and
Eastern Canada…
Wildfires continue to burn over northern and central California, west
central Oregon, central and eastern Washington, northern and central
Idaho, and western Montana, along with southern British Columbia of
southwestern Canada resulting in an expansive area of smoke which
stretches from off the U.S. west coast inland over sizable portions of
the lower 48, parts of southwestern, south central, and eastern Canada,
to well off the east coast of Canada and the U.S. east coast over the
northern Atlantic. Within this huge expanse of thinner density smoke
were some thicker areas. Moderately dense to thick smoke was visible
over portions of the interior northeastern U.S. and extending northward
into southern and central Quebec before arcing to the northeast and east
across northeastern Quebec and the Labrador Sea. Closer to the active
wildfires was a broad area of moderate to thick density smoke which
impacted northern and central California, northwestern Nevada, a good
chunk of Oregon and Washington, northern Idaho, and southern British
Columbia. A separate swath of thicker density smoke was visible across
southern Montana and western Wyoming. Significant cloud cover across the
central U.S., the Great Lakes region, and south central Canada including
Hudson Bay greatly limited smoke detection in satellite imagery. Smoke
modeling analysis and short term forecast was showing a significant
amount of smoke in this cloud covered region.
DUST:
Texas/Gulf of Mexico/Cuba/Caribbean Region...
A swath of remnant thin density Saharan dust was visible this morning
across the Florida Keys and over the central and western Gulf of Mexico
and inland over eastern Mexico and southeastern Texas possibly extending
well inland over Texas and eastern Mexico. Another batch of relatively
thicker Saharan dust was seen spreading to the west over Hispaniola,
Puerto Rico, and the eastern Caribbean region.

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
