DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0130Z UTC August 26, 2007

Montana/Idaho:
The numerous wildfires scattered across western Montana and central
to south central Idaho flared up again this afternoon resulting in
massive moderately dense to dense smoke plumes which spread quickly to
the east-northeast. High level cirrus clouds also moved across a portion
of this region which hindered additional details concerning the density
and the extent of some of the smoke.

Wyoming:
A burst of dense smoke was observed early this evening moving to the
east-northeast from a fire in western Park County of northwestern Wyoming.

California/Nevada/southern Idaho:
The ongoing fires in Santa Barbara County of southern California continued
to emit large quantities of moderately dense to dense smoke which moved
mainly in a north to north-northeasterly direction during the day. Some of
the thinner smoke from today and residual smoke from yesterday had fanned
out as well to the east into west central and south central Nevada. Some
of the smoke may even have moved farther to the northeast into central
and even northeastern Nevada. However, blowing dust/sand from some of
the dry lake beds primarily in northwestern and western Nevada may be
responsible for much of what is seen in visible imagery extending from
central Nevada across southern Idaho. This area of what is believed to
be primarily blowing dust/sand was moving to the east-northeast.

Washington/Northern Idaho Panhandle:
A combination of smoke from several fires as well as some blowing dust
was visible across central and eastern Washington moving to the northeast
into the northern panhandle of Idaho.

Arizona:
Early in the day, moderately dense to locally dense smoke was visible
moving and fanning out mainly in an easterly direction from fires located
in central Coconino County of northern Arizona. Clouds moved across the
area later in the day preventing any further details concerning the smoke.

North Central US:
Residual patches of thin smoke primarily from the Montana/Idaho fires
and also perhaps a very small contribution from the Santa Barbara County
California fires were seen moving to the east over Wyoming and Nebraska,
the Dakotas, southern Minnesota, Iowa, southern Wisconsin, and northern
Illinois.

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.
