Alaska/Northwestern and Northcentral Canada:
A cloud shield has spread across western Alaska this evening inhibiting
smoke detection. However the large number of fires across interior
Alaskan continue to produce an area of dense smoke that covers much of
the eastern half of the state and drops southward over the Cook Inlet
and Kodiak Island and continues south into the Gulf of Alaska. The smoke
also has spread eastward to cover roughly the northern half of the Yukon
Territory and the northwest portion of the Northwest Territories north
and west of Great Bear Lake.

A separate area of moderate smoke can be seen farther east over much
of Nunavut and extending into northern portions of Manitoba and just
reaching the northwest shore of Hudson Bay.

Northern Rockies:
Numerous fires over northern Idaho are producing moderately dense to
dense smoke over much of northern Idaho and into western Montana.

Pacific Northwest:
A fire over southwest Oregon is producing an area of moderately dense
smoke that extends northward along and west of the Cascades into western
Washington. The smoke also extends to the southeast of the blaze in
southwest Oregon.



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.
