THROUGH 0030Z September 9, 2005

Northern US Plains and Upper Mississippi River Valley:
A large area of moderately dense smoke is along a line and on average
300km wide from Miles City, MT northeast to Bismark, ND then southeast
to Aberdeen, SD to Des Moines, IA to Burlington IA.   This covers the
eastern third of MT, all of ND, the NE half of SD, the western quarter
of MN, and all of IA. This smoke is from the multiple large fires burning
in ID and MT from last evenings activity.

NE Minnesota:
A fire that has been burning across NE St. Louis county NW of Ely is
producing a fan shape plume that extends about 100km from the NE to the
E across the Canadian boarder and nearing the coast of Lake Superior.

The Hazard Lake fire along the Lewis and Clark and Teton county line
is producing dense smoke in a 16km wide line to the NE 200km to SW Hill
county, MT.

Convectively dense smoke from multiple fires including the Valley Road,
Gregory, Frank Church, Mustang, Red River Complexes covers the following
counties in Idaho: NW Custer, Lemhi, SE half of Idaho and counties
in Montana: Ravalli, N Beaverhead, Granite, Deer Lodge, Silver Bow,
Jefferson, Broadwater, Meagher, Cascade, Judith Basin, S Lewis and Clark,
Powell, S Missoula. The smoke is more concentrated and extends further
NE due to stronger upper-level flow with a strong jet ahead of a digging
upper level trough.

Thin smoke from multiple smaller fires (most likely agricultural)
covers the remainder of the chimney stack of ID including the counties
of Clearwater, Shoshone,S Bonner, Kootenai, Benewah, Latah, Nez Perce,
Lewis, and the remainder of Idaho county that is not covered by the
aforementioned dense smoke.



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.
