DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0100Z October 7, 2021
SMOKE:
U.S./Canada/Northern Mexico/Gulf of Mexico/Northern Atlantic...
Smoke extends from wildfire activity across the southern Sierra Nevada
in California north-northeastward across Nevada, Utah, Idaho, and
Montana. Further wildfire activity across northern Idaho and western
Montana is replenishing the smoke layer as it moves into Alberta and
Saskatchewan, where further wildfire activity is contributing smoke. It is
over central Canada where the smoke moves north then east-southeast around
a ridge over the Dakotas and Saskatchewan. From here, the smoke extends
east-southeast across northern Ontario, central Quebec and northern
portions of the Maritime Provinces and out into the Atlantic. A trough
over the Davis Strait is dragging some smoke northwards toward southern
Greenland. The thickest smoke resides near and in the valleys downwind
(north-northeast) of the KNP Complex and Windy Fires in the southern
Sierras, as well as across south-central Canada, where a large wildfire
is contributing thick smoke moving northward below a moderate to thick
layer of smoke aloft. Due to the presence of cloud cover over western
North America, the exact extent and continuity of the layer of smoke
is uncertain.
Southwestern CONUS/far NW Mexico…
A single fire ignited this morning/early afternoon on the California side
of the Colorado River, producing a light to moderate smoke plume that
moved northward. A quite thin layer of remnant smoke was also noted,
with the possibility some agricultural burning contributing some to
smoke noted straddling the California/Baja California border.
Oregon…
A couple individual fires in central Oregon were noted producing light
to moderate smoke. Winds were moving smoke predominantly to the east
or northeast.
Southern Manitoba/North Dakota…
Scattered fire activity, presumably of a mixed controlled and agricultural
burning nature, was observed emitting mainly light smoke with a few
producing moderate smoke in southern Manitoba. Much of the The smoke
was moving off toward the north or north-northeast.
South-central CONUS…
A layer of thin density remnant smoke was observed moving south across
Texas, with some extending just across the Rio Grande and the state
borders with Oklahoma, Arkansas and Louisiana, as well as out over the
far northwestern Gulf of Mexico. A small area of moderate density smoke
was observed within the larger area of light smoke over and to the south
and southwest of Houston.
DUST:
Atlantic…
An area of thin density Saharan dust was still visible over and to the
east of the Bahamas and to the north of Puerto Rico and Hispaniola. More
dust can be seen over the tropical and subtropical Atlantic extending
eastward to the Sahara

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
