DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0200Z September 26, 2011

Southern Canada/Northwest US:
Thick smoke again emanated from several fires in northwestern Wyoming
during the day. The smoke spread mainly in a north and northeast direction
reaching south central Montana just prior to sunset. Detached thin
to moderately dense smoke from these fires as well as ones burning in
eastern Idaho and western Montana was visible again during the afternoon
and early evening extending from south central Wyoming northward to
central Alberta and central Saskatchewan in Canada. Cloudiness moved
across Idaho and western Montana during the afternoon which interfered
with information concerning smoke extent and density in that region.

Arizona:
Moderately dense to locally thick smoke from a fire in south central
Arizona moved in a northward direction during the afternoon and
evening. Thinner density smoke from this fire extended as far north as
southern Utah.

North Dakota/Northern Minnesota/South Central Canada:
Numerous fires which were believed to be primarily agricultural burns
were analyzed again during the day across portions of North Dakota,
northwestern Minnesota, southeastern Saskatchewan, and southern
Manitoba. A number of relatively small smoke plumes were detected with
these fires. Please refer to the graphics on the web pages below for
more information on these fires and smoke plumes.

Earlier this Morning...
Central Plains:
An area of what is presumed to be mainly remnant smoke is present in
the central plains over the far eastern Dakotas, southern Minnesota,
all of Iowa, northern Missouri, and western portions of Illinois and
Wisconsin. The smoke density is difficult to discern due to a high level
cloud shield associated with low pressure system in the area, but gaps
in the clouds as well as aerosol optical depth measurements indicate
that the smoke is of thin to moderate density. The origin of this smoke
is from several large wildfires located in Idaho and Wyoming that were
producing heavy smoke yesterday and days prior.

THIS TEXT PRODUCT IS PRIMARILY INTENDED TO DESCRIBE SIGNIFICANT
AREAS 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

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.
