The cluster of large fires burning in the Okanogan National Forest in
north central Washington state were responsible for a large area of
locally dense smoke which was spreading southward and covered most of
Okanogan county, portion of Chelan county, and all of Douglas and Grant
counties. The residues from this fire burning yesterday night and this
morning has covered southern Washington, northern Oregon, and panhandle
area of Idaho. The large fire in Deschutes county of Oregon is still
burning this evening and is producing a very dense plume of smoke that
is fanning out and has covered most of Linn county and northeastern part
of Lane county of Oregon.

Northern California:
Two fires in Siskiyou county of northern California are producing
moderately dense to locally dense plumes of smoke that are swirling
around the boundary among Siskiyou, Trinity, and Humboldt counties.

The very large fires burning in central Elko County of northeastern
Nevada are producing massive plumes of dense smoke moving northeast
and cutting the southeastern corner of Idaho to the boundary between
Idaho and Wyoming. The big fire along the border of Teton and Fermont
counties of Wyoming is still burning and producing a moderately dense
to locally dense plume of smoke moving northeast across Fermont and Park
county to the eastern Big Horn county in northern Wyoming. Another fire
in northwestern Bingham county of Idaho is producing a narrow  plume
of moderately dense smoke moving northeast across Jefferson, Madison,
and Teton counties to the boundary between Idaho and Wyoming.

Two large fires in central Pittsbrug county and southern Murray county
of Oklahoma are producing moderately dense to locally dense plumes of
smoke moving northward. The smoke from the fire in Pittsburg is covered by
clouds, so it is difficult to tell how significant the smoke is; however,
the dense smoke from Murray fire has extended about 90 km to the north NE.

Several fires eastern Lake Winnipeg near border between Manitoba and
Ontario provinces of Canada are producing moderately dense plumes of
smoke moving eastward across the border to central western Ontario.



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.
