THRU 1600Z August 11, 2005

Northern Rockies/High Plains:
A wispy area of smoke was seen along a north/south axis stretching from
north central to south central Wyoming and moving to the east. A thin
area of smoke was seen over much of Montana, although it was mixing with
clouds making detailed assessment difficult.

Pacific Northwest/Idaho:
Numerous fires over southeast Washington and northern Idaho were
producing locally dense smoke near Kooskia in Idaho and near Pomeroy
in Washington. Thinner smoke covered much of the rest of north central
Idaho and was moving to the east. The Blossom Complex fire in southwest
Oregon was producing a plume of smoke extending to the southwest off the
Pacific coast. The plume then became quite thin and turned and extended
southward off the coast as far south as Point Reyes California.

A fire in the Kings Canyon/Sequoia National Parks area is producing a
moderately dense smoke plume extending to the west toward the central

Alaska and northwest Canada:
The numerous fires in Alaska and Yukon Territory are producing a large
area of thick smoke. The most dense smoke is mainly between the Alaska
and Brooks Ranges and east of a McGrath/Allakaket line and extending
eastward into the northern half of the Yukon Territory and into the
Northwest Territories. A thinner area of smoke is seen extending north
across the Brooks Range into the Beaufort Sea. The smoke area thins
somewhat and turns to the southeast reaching the southern border area
between the Yukon Territory and the Northwest Territories.

Southern Ontario:
A patch of smoke from fires west of Lake Nipigon was seen over southern
Ontario along and east of the eastern end of Lake Superior nearly reaching
Sault St Marie.



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.
