DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THRU 1500Z JULY 28, 2005

Alaska/NW Canada:
Much of the Yukon valley of central Alaska remains covered in thick
smoke from the numerous fires across the region. Smoke extends from the
central Yukon Territory westward across Alaska and is mainly moving to
the west. The smoke area fans out across western Alaska and extends off
the northwest coast into the Chukchi Sea and is also being drawn into
southwest Alaska over the Taylor Mts around the back side of a deep low
pressure system in the Gulf of Alaska.

An area of moderately thick smoke is seen from just west of Great Slave
Lake extending to the southeast to the eastern end of Lake Athabasca in
northern Saskatchewan.

Oregon:
Moderately thick smoke is still being actively produced from a fire
northeast of Ashland in Jackson county was seen drifting both to the
east and west but was mainly confined to Jackson county.

Wyoming:
A small area of smoke was seen drifting to the east across central
Wyoming. It was detached from the fire source which is believed to have
been in Lemhi county in eastern Idaho.

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.
