DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0050Z September 20, 2020
SMOKE:
United States, Central Canada, Northern Atlantic...
Remnant smoke from wildfires occurring across the western U.S. continues
to affect a large swath of the country this afternoon. Moderate-to-heavy
density smoke covers most of the Great Plains including Texas, Oklahoma,
western Arkansas, Kansas, Missouri, Nebraska, western Iowa, and the
Dakotas, extending further north into central Canada (Alberta and
Saskatchewan). Lighter density smoke extends outward from the main plume
above for a few hundred miles, affecting the northwestern U.S., British
Columbia, Manitoba, Minnesota, Wisconsin, Illinois, Indiana, western
Kentucky, western Tennessee, central-northern Louisiana, central-southern
New Mexico, southern Arizona and northern Mexico. The portion of the
smoke over the northern Great Plains was being pushed east towards the
Great Lakes, while the areas along the Mississippi Valley were seeing
an additional influx of smoke from local agricultural burning. After a
relative reduction in smoke emissions yesterday, all major wildfires in
California were again releasing heavy smoke this afternoon impacting the
entire state with the exception of areas south of Los Angeles county with
plume trajectories generally moving towards the east and into Nevada. In
addition to that, the Mullen Fire in southern Wyoming was emitting a
very thick smoke plume towards the northeast and into southwestern South
Dakota. A second large plume of light-to-moderate smoke also linked to
western U.S. wildfire emissions is seen extending for hundreds of miles
over the northern Atlantic and moving east-northeast towards the U.K.

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
