DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1730Z September 25, 2011

Southern Canada/Northwest US:
Thin density smoke covers much of northern Wyoming, central and eastern
Montana, southern Alberta, southern Saskatchewan, and southwest Manitoba
this morning. An elongated patch of moderate to thick density smoke is
observed stretching north-south over central Montana, and a round area
of moderate density smoke is observed  in southwest Saskatchewan. This
smoke originated from wildfires in Montana, Idaho, and Wyoming.

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.
