DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THRU 0100Z JULY 25, 2005

Alaska/Yukon:
Numerous large Alaskan fires continue unabated and the accompanying large
band of smoke of various densities extends from the Yukon through central
Alaska and then out across the Bering Sea.  The smoke covers more than
a third of Alaska tonight and is very dense in some areas.

Ontario:
Two fires north of Lake Nipigon and one fire south of the Lake have fairly
large and dense smoke plumes that extend toward the east.  The smoke
from the southern fire reaches the northernmost tip of Lake Superior.

Western U.S./Northern Central Plains:
The fire in southeastern Crook County, Wyoming continues to produce
fairly thick smoke over several counties in South Dakota.  A fire that
began midday in Fergus County, Montana is producing smoke that affects
several counties to its east.  A new fire near the border of San Benito
and Monterey counties in California is sending a fairly small and diffuse
smoke plume mostly toward the south and east.

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.
