United States:
The smoke from yesterday and this morning with the smoke produced by
just those fires in northwestern US and southern Canada burning today
continues to move to the south and east. The smoke now almost moved
out from Canada and already reached to the east coast. Therefore, the
smoke has covered all the United States but the southwestern states,
including California, Nevada, Arizona, and New Mexico.

The main source of this smoke is the enormous wildfire in Okanogan
National Forest on the border of northern Washington and southern
British Columbia. There is also a large wildfire burning in Umatilla
National Forest that is contributing to the massive area of smoke. The
large amount of fires spreading through central and northern Idaho and
large fires in southwest Montana are contributing a significant amount
of dense to very dense smoke to this massive area as well.

The big fire along the border between Ventura and Los Angeles counties
is producing a very dense plume of smoke that is fanning out to the
southeast and has covered all the Los Angeles county. The densest portion
of the smoke is affecting the L.A. Metro area and the relatively thin
portion of the smoke has covered a very large area including Riverside,
Kern, and San Bernardino counties. Another big fire in Placer county
of central California is still burning today and producing a massive
area of dense smoke that is fanning to the north. It has covered the
counties, including Nevada, Sierra, Butte, and Yuba, in the north of
Placer county. Numerous fires in Trinity and Siskiyou counties of northern
California are still burning and producing dense plumes of smoke that is
moving to the west and reaching the Pacific. The smoke has covered all of
Trinity, Humboldt, and Del Norte counties, and western portion of Siskiyou
county in northwestern California, and the southwestern corner of Oregon.

Dense smoke from fires in western Ontario has moved to the south across
the province reaching the US border.



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.
