THROUGH 1530Z September 29, 2006

The fires in northern California in Trinity and Siskiyou counties continue
to produce smoke. The smoke has settled into the valleys surrounding the
fires and is locally dense. Additional smoke has become lofted to higher
levels and the plume extends to the northwest into southwest Oregon and
out into the Pacific ocean this area is moderately dense. The smoke over
the Pacific is difficult to delineate due to extensive low level clouds
but it appears to extend up to 225 km offshore. The smoke then curves
back to the east and becomes mainly thin with a narrow ribbon about 50
km wide extending from the central Oregon coast eastward across central
Oregon and into southwest Idaho. The smoke extends to the southeast into
south central Idaho along the Utah border  and into southwest and south
central Wyoming. The smoke over southeast Idaho and Wyoming likely is
mixed with smoke from fires in central Idaho. Fires in Custer, Boise,
Valley and Clearwater counties in Idaho are producing locally dense
smoke in the valleys in their immediate vicinity.



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.
