THROUGH 1600z September 01, 2006

Great Lakes/Ontario/Quebec:
An area of remnant smoke can be seen over parts of eastern Wisconsin,
the upper peninsula of Michigan and Lakes Superior and Hudson. The
smoke also covers portions of southeast Ontario, James Bay, the eastern
portion of the length of Hudson Bay and western Quebec. The smoke over
the US and the Great Lakes is mainly thin while much of the smoke over
Canada is moderately dense. A separate area of thin smoke is mixed with
a cloud mass over northwest Ontario and extreme eastern Manitoba. All
of the smoke originated from the numerous fires in the western US.

Moderately dense smoke, with locally dense smoke in the valleys, is seen
over Park and Sweet Grass counties in southwest Montana. The smoke covers
most of these counties and is slowing moving to the east.

Several fires in central Idaho, mainly in Valley, Idaho and Custer
counties, are producing smoke which has mainly settled in the valleys
in the vicinity of the fires. The smoke is locally dense. The smoke that
is escaping the valleys is mainly thin and drifting to the west.

A large fire in southern Columbia county is producing a moderately dense
to locally dense smoke plume that is drifting to the west southwest along
the Oregon/Washington border and reaches nearly to the Pacific coast. The
fire is Okanogan county is producing moderately dense smoke in the local
area that is drifting to the west within about 30 km of the fires.

The large fires over Trinity and Siskiyou counties are producing
moderately dense to locally dense smoke in the valleys that is moving to
the northwest. The smoke stretches from the fires into southwest Oregon
and into the Pacific about 75 km off the central Oregon coast.



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.
