DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0250Z September 20, 2021

SMOKE:
Atlantic...
A light to moderate density detached plume leftover from western
U.S. wildfires covered the area just of the Mid-Atlantic to Bermuda.
Another thin density plume, also left over from western U.S. wildfires,
was detected east of Bermuda for several hundred miles.  Yet another
detached thin density plume was found extending northeast of
Newfoundland to a few hundred miles southwest of Iceland.

Continental U.S./Canada/Mexico...
A large thin density plume from western U.S. wildfires covered much
of the Desert Southwest, the Great Basin, parts of the Rockies and
most of the Plains, the Midwest, the Great Lakes region, the Ohio
Valley, and Mid-Atlantic.  This same thin density plume also covered a
large part of south-central and southeastern Canada, and parts of
northwestern Mexico and Baja California.  Within this thin density
plume, a moderate density plume was found over parts of the Desert
Southwest extending northeastward to south-central Canada and
southeastward over the Great Lakes into parts of the Mid-Atlantic.
A detached moderate density plume was located over southeastern Texas.
A thick density plume from wildfires in the San Joaquin Valley in
California was spread across parts of southern California, the Great
Basin, Arizona, and the central Rockies extending northeastward through
the Northern Plains and south-central Canada

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:

ANY QUESTIONS OR COMMENTS REGARDING THIS PRODUCT SHOULD BE SENT TO:
SSDFireTeam@noaa.gov

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.
