DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0130Z September 23, 2007

Lower Mississippi Valley:
The massive amounts of agricultural fires along the Mississippi River
are producing brief, light plumes of moderately dense smoke that is
moving to the east southeast of the cluster of fires.

In southeast Arkansas, several fires are producing plumes of moderately
dense smoke that is moving to the southwest.

Wyoming:
Fires located across Washakie and Hot Springs counties are producing
moderately dense to dense plumes of smoke that is extending to the
northeast and just reaching the borders of Montana and South Dakota.

South Dakota:
A fire located in Custer county of southwest South Dakota is producing
a plume of light smoke that is moving to the northeast.

There is also an area of smoke/dust that is moving across South Dakota
and into Minnesota.  The source of this is unable to be determined due
to heavy cloud cover in the northwest US.

Pacific Northwest:
Cloud cover continues to hamper smoke detection over much of the Pacific
Northwest, where large fires have been producing excessive amounts of
smoke over previous days.

Alaska:
In north northeast Alaska there is a large fire producing a plume of
dense to very dense smoke that is moving to the east.

Canada:
Several of the fires in southern Maniitoba are producing very light
plumes of smoke that are moving directly to the north.

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.
