THROUGH 1630Z August 25, 2005

Northern and Western Canada:
Moderately dense smoke from the Alaskan fires extends across the Islands
of the NW Territory to NW Baffin Island.  All of the smoke is contained
N of 65N, except for an area of thin smoke that extends south along 110W
into a well defined cyclone over South-central Saskatchewan.  Moderately
dense smoke can be seen along the northern and western periphery of
the cyclone, with the most dense further north nearer to the orginal
source in AK.  The smoke can be seen swirling around in an area from N
Saskatchewan across E Alberta south into NW MT along the eastern slopes
of the Rockies.  Smoke most likely exists across most of S Saskatchewan
as well, but clouds near the cyclone center make it difficult to see.

Intermountain West:
A swath of thin smoke 140km wide extends from the ID/NV line near Jackpot,
NV to the ENE near Buffalo SD and is focused along the convergent band
S of the Saskatchewan cyclone.

A dense plume of smoke from the Harding fire in E California is 19km
wide and extends NNE to just N of Pyramid Lake then moves ENE across
the southern Black Rock desert and S Humbolt county to near Midas,NV in
W Elko county.

Resuspended volcanic ash due to high winds near Mount St. Helens is
causing a moderately dense plume to the NW about 60km and is about
17km wide.



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.
