DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1700Z July 4, 2021
SMOKE:
Much of Canada/Alaska/eastern half of the CONUS/Atlantic Ocean...
Widespread wildfire activity continues across British Columbia,
eastern Manitoba, and western Ontario, continuing to produce thick
smoke. Smoke from the British Columbia wildfires has been confined
to mainly valleys near individual wildfires, but has contributed to a
light to moderate remnant area of smoke extending mainly eastward across
southwestern and south-central Canada. Once the layer reaches Manitoba,
there is a significant increase in density thanks to the active wildfire
activity there. This area of wildfire activity is producing thick smoke
that extends northeastward, while moderate density remnant smoke from a
combination of the British Columbia and central Canada wildfires (possibly
with minor contributions from fires in northern California) is observed
extending from northern Ontario into the Ohio River Valley. The smoke
thins over Arkansas, northern Mississippi, northern Alabama, northern
Georgia, and the Carolinas before concentrating to moderate density
behind a cold/stalled front over the Gulf Coast and then moving along
that front out over the Atlantic Ocean and into a cyclone south of the
Canadian Maritimes. Some is possibly seen out east of the frontal system,
but could be mixed with Saharan Dust.
Some remnant smoke may also be seen moving southwest out into the Pacific
Ocean and toward the northwest across northern British Columbia, Alaska,
the Yukon, and the Northwest Territory. The smoke over Alaska, the Yukon,
the Northwest Terrotory, and northern British Columbia was light to
moderate, and could perhaps have contributions from Alaskan Wildfires and
transport from Siberia and/or China. It is also possible that there are
currently active wildfires across western Alaska, where current cloudy
conditions could be obscuring smoke from an active wildfire.
Intermountain West...
Wildfires in northern California are producing moderate to, at
times, thick smoke in the valleys adjacent to the locations of these
wildfires. This persistent wildfire activity has helped produce a mainly
thin area of remnant smoke that blankets western Idaho, eastern Oregon,
far northwest Nevada, and northern California.
Quebec…
A persistent fire in central Quebec began producing smoke again late this
morning. The light to moderate smoke was observed moving north-northeast.

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
