THROUGH 0200Z August 5, 2006.

California/Oregon/Idaho/Washington/Montana/southwestern and south
central Canada:
The Tripod complex north and northeast of Twisp, Washington in the
Okanogan Range is still producing dense low level smoke that is moving
due east and covers nearly all of Okanogan county east of the Chewuch
River. Large fires across northwestern California, including Hunter,
Orleans, Bar, Kingsley, Panther, Mendocino and Uncle Complexes have
produced a veil of moderately dense to locally very dense smoke in the
mid to upper levels of the troposphere.  The smoke is being stretched
out by upper level winds into a line that has connected with the smoke
from Washington and extends from northwestern California and offshore
waters across central Oregon from the SW corner to the northeastern
corner and is about 141km wide. The complex smoke then continues to
extend across almost the whole of Washington and across northern Idaho
(covering Nez Perce and Shoshone counties) into northwestern Montana,
Saskatchewan to the southern tip of Lake Manitoba.

Mid Atlantic coast:
A large area of aerosol is seen emerging from the US East Coast ahead
of the approaching cold front.  The area extends from the southern New
Jersey coast southwest to the southern tip of the Delmarva and across
the coastal flats of the Carolinas and Georgia.  The area seen is on
average 350km wide (from NW-SE) and at its widest is more than 500km wide.

Louisiana/northeastern Texas:
Several narrow plumes of mainly thin smoke were seen across this region
during the afternoon and early evening. The plumes were all moving to
the northeast or north and were mainly less than 50 km long.

NW Canada:
Smaller pockets of moderately dense to locally dense smoke surround the
Great Bear Lake from fires around the lake, which is moving north toward
the Arctic Circle. A thin plume of smoke seen in the evening GOES WEST
imagery is swirling around northern Yukon Territory panhandle area.



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.
