THROUGH 1430Z September 9, 2005

Northern Rockies/Northern Plains/Upper Midwest/Upper and Middle
Mississippi Valley/Ohio Valley:

A large area of moderately dense smoke associated with the fires in
central Idaho is spreading across a large section of the U.S. The smoke
seen in morning GOES-10 satellite imagery begins in northwest Montana
near the Great Bear/Bob Marshall/Scapegoat Wilderness with a nearly
200mi wide smoke plume extending east across the northern third of
Montana and North Dakota and southern parts of Alberta and Saskatchewan.
The moderately dense smoke plume then extends southeast through all of
Minnesota and the western half of Wisconsin to Illinois/Indiana/Kentucky
where it then extends easterly along an axis approximated by the Ohio
River to western portions of Ohio.

Fires in central Idaho are producing a dense area of smoke which is mixed
with clouds from approaching weather system over the Pacific northwest.
The smoke appears to extend to northwest Montana where it joins the
above mentioned plume near the Wilderness.



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.
