DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1445Z July 28, 2006.

Northwest U.S./ Northern Plains:
GOES-12 imagery showed areas of extensive smoke from the Northern
Rockies to the Upper Mississippi Valley. Large fires in W Elko County in
N Nevada caused very dense smoke that drifted eastward to N Utah an SW
Wyoming. Numerous fires in E Wyoming/ NW Nebraska/ and SW South Dakota
caused another area of very dense smoke over the Dakotas and N Minnesota.

Central Canada:
Numerous fires just south of Lake Athabasca produced thin and moderately
dense smoke that drifted to the SE over Saskatchewan and  central
Manitoba.

Alaska:
Fires in Yukon-koyukuk County in NE Alaska caused a large area of thin
smoke that moved to the NE over N Yukon and the Beaufort Sea.

Brown

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.
