THROUGH 1600Z August 27, 2006

Washington/Oregon/Southwestern Canada/Northern Idaho/Western Montana:
The large fires in Okanogan County of Washington continue to burn and
along with another significant fire slightly to the southwest in Chelan
County are responsible for a large mass of moderately dense to locally
dense smoke (closer to the fires) which has spread northward this morning
into south central British Columbia of southwestern Canada. A thinner
swath of smoke was also visible moving in a southeastward direction across
far eastern Washington and over the Idaho panhandle and western Montana.

South Central Idaho/Southeastern Washington:
Localized patches of moderately dense smoke were noted scattered across
this region due to a number of fires.

Montana/Wyoming/Northern Plains/Upper Mississippi Valley:
A large amount of cloudiness is present over a portion of this region
hindering smoke detection. In the relatively cloud free spots morning
visible satellite imagery did indicate some possible detached patches
of thin smoke over eastern Montana and extreme northern Wyoming as
well as across southern North Dakota, central and southern Minnesota,
and central Wisconsin to Lake Michigan.

For a number of days now the fires in Siskiyou and Trinity counties in
northern California continue to emit very locally dense smoke which has
had a history of spreading westward during the overnight and morning
hours and across Humboldt County. The thickest smoke is especially
visible in the valleys of southwestern Siskiyou, northern Trinity, and
northern Humboldt Counties. Some of the thinner smoke appears to have
drifted northward into far southwestern Oregon.

A small thin smoke plume was noted this morning moving to the southwest
from an active fire in central Lincoln County of southeastern Nevada.



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.
