DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1700Z September 21, 2020

SMOKE:
CONUS, Central and Eastern Canada, and Northeastern Mexico…
Wildfire activity across the western CONUS (mainly California and Oregon)
was observed continuing to produce thick smoke this morning. The smoke
plume from this fire activity is stretching from the source activity
northeast and then east across Nevada, the southeastern half of Oregon,
southeastern Washington State, southern Idaho, northern Utah, and along
the Wyoming and Colorado border out across the Central Plains. From here,
the moderate density smoke is being drawn northeastward and northward
into a large cyclone centered over eastern Manitoba and northwestern
Ontario. At the same time, some of the smoke is being drawn southwestward
into a small ridge over the Four Corners region, where the smoke is
thinning and dissipating. As a result of both features, a large area
of moderate to thick smoke blankets a region from northern Texas into
James Bay and Hudson Bay in central Canada. Smoke is moving further along
across Quebec, Newfoundland, and New England and sagging southeastward
and southward. Some of the smoke is also being drawn around the western
side of Hurricane Teddy, located southeast of Bermuda. Light remnant smoke
was also observed over the southeastern CONUS and the Intermountain West.

Central and Eastern Atlantic Ocean…
Detached light to moderate remnant smoke was also observed over the
mid-latitudes of the central and eastern Atlantic. This area of smoke
was being transported to different ways...one northeast into the UK
and the other clockwise around an upper feature near the Azores. A few
other entities, such as Hurricane Teddy and the remnants of Paulette,
are also slightly affecting how the remnant smoke is moving through the
upper feature.

Mid-Mississippi Valley…
Light smoke plumes from seasonal burning activity was observed early this
afternoon across northeastern Arkansas and the bootheel of Missouri. The
smoke was moving off mainly toward the west-northwest.

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
FIRE IN VARIOUS GRAPHIC FORMATS ON OUR WEB SITE:

Unless otherwise indicated:
  • Areas of smoke are analyzed using GOES-EAST and GOES-WEST Visible satellite imagery.
  • Only a general description of areas of smoke or significant smoke plumes will be analyzed.
  • A quantitative assessment of the density/amount of particulate or the vertical distribution is not included.
  • Widespread cloudiness may prevent the detection of smoke even from significant fires.
