THRU 0230Z JULY 26, 2005

Alaska/Yukon/British Columbia/Alberta/Saskatchewan:
Scattered intense fires burning across west central to east central
Alaska and Yukon Province of northwestern Canada are producing locally
very thick smoke. The overall massive area of smoke has expanded and
spread westward across Alaska to the Bering Strait and Kotzebue Sound,
then northward over the Arctic Ocean. A portion of the smoke area on
the eastern end has actually spread southeastward during the day into
northern British Columbia Province. Even farther to the southeast patchy
smoke was visible at times in cloud free areas moving slowly eastward
across portions of Alberta and Saskatchewan Provinces. This smoke is
also likely from the Alaska/NW Canadian fires.

A few fires detected over southern and southeastern Ontario and
southwestern Quebec Province were producing some smoke which had generally
been moving eastward during the day. Some of the smoke may have grazed
the northern sections of Lake Superior and Lake Huron.

Western U.S.:
A lot of cloudiness due primarily to monsoonal convection covered
Arizona, Utah, New Mexico, and Colorado making it difficult to detect
any wildfires or smoke. Several fires were observed producing smoke
plumes across portions of Washington, Oregon, northern Idaho, and
western Montana. The smoke plumes were spreading mostly to the south
or southeast. Visible imagery also showed what appeared to be blowing
dust coming from a source region in northeastern Owyhee County of SW
Idaho. The apparent dust cloud was moving southeastward into northern
Utah and closing in on the Salt Lake City region.


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.
