DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1700Z August 6, 2019
SMOKE:
Northwestern U.S./North Central and Central U.S./Southwestern and South
Central Canada...
A broad region of mainly thin density smoke attributed primarily to
wildfires burning in Washington, Idaho, western Montana, Oregon,
and northern Nevada was visible this morning stretching from the
Pacific Northwest eastward to at least as far east as Minnesota,
Wisconsin, and Iowa. The thinner density smoke also was noted extending
across southwestern and south central Canada from British Columbia to
Ontario. A swath of moderately dense smoke associated with the fires
in northern Nevada was seen over southeastern Idaho, southern Wyoming,
and into northern Colorado. A patch of moderately dense to thick smoke
was present over eastern Washington and northern Idaho near wildfire
activity there with localized thicker smoke also seen closer to some
of the wildfires burning in western Montana, northeastern Oregon, and
southwestern Canada/north central Washington state.
Western Canada...
A large wildfire burning in northwestern British Columbia was responsible
for thin to moderately dense smoke which covered northwestern and central
British Columbia. More localized thicker smoke was seen near and to the
west of the wildfire.
Northwestern and Central Canada...
Smoke of generally thin density was seen in between breaks in the clouds
over the western and southern portion of the Northwest Territories as well
as northern Alberta, northern Saskatchewan, and northern Manitoba. This
leftover smoke could still be due in part to recent wildfire activity
in northwestern Canada and Alaska which has diminished quite a bit in
the past week though some contribution from major wildfire activity in
Siberia-northern Russia could also be occurring.
Area from the South Central U.S. to the Northeastern U.S...
An aerosol of unknown origin/composition was seen early this morning over
the region stretching from the Lower Mississippi Valley to the interior
portions of the Northeast. It is not known if this aerosol was composed
of any residual smoke or if it is mainly other atmospheric pollutants.

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
