DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1740Z September 16, 2021

SMOKE:
Eastern U.S. and Canada/Atlantic...
A detached plume left over from the western U.S. wildfires was detected
over the Mid-Atlantic and extended over parts of the northwestern
Atlantic,
Nova Scotia, Newfoundland, and to just south of Greenland.  The plume was
of thin density except moderate density just south of Nova Scotia to the
southeastern part of Newfoundland.

Western U.S. to Great Lakes...
Ongoing wildfires in California and Oregon have spread a large thin
density plume that covered parts of California and Oregon, the Great
Basin, parts of the northern Rockies, the northern Plains and Midwest,
and sections of the Great Lakes region.  Within this thin density plume,
plumes of moderate density was detected over western Oregon, parts of
northern and central California and the Great Basin.  This plume then
extended east-northeast over southern Idaho, most of Wyoming, and the
western part of the Northern Plains.  Heavy density plumes are found in
the immediate vicinity of one large wildfire complex over northwestern
California, and another smaller complex in the San Joaquin Valley.

Desert Southwest/Mexico/Pacific...
A detached thin density plume originally sourced from wildfires over
the western U.S. covers a small part of southern California/Arizona/New
Mexico and a large part of northwestern Mexico and Baja California.


DUST:
Atlantic...
A thin plume of Saharan dust was detected over the eastern Caribbean Sea.

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.
