DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THRU 1530Z August 06, 2005

Alaska:
Dense cloud cover this morning prevents observation of the persistent
smoke that has been in Alaska and neighboring areas.

Northwest Territories and adjacent areas:
A large area of moderate smoke extends from south of Great Bear Lake
across Great Slave Lake to south and southeast of Lake Athabasca.

Southwestern Canada:
A fire in southern British Columbia has a large light to moderate smoke
plume that extends eastward into Alberta and possibly into Saskatchewan.

Northwest U.S.
Last night's numerous fires and resulting smoke plumes in Washington,
Idaho and western Montana have not yet become apparent this morning,
except for a fire in extreme western Ravalli County, Montana that is
currently accompanied by a plume extending eastward.  An eastward-moving
area of thin smoke in eastern Montana is a remnant of last nights fires.

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.
