THROUGH 0215Z August 31, 2005

NOTICE...Local satellite outage between 22Z and 01Z has prevented a
complete smoke analysis. Only had a very brief view of smoke in the far
western U.S. just prior to sunset with GOES-10 imagery after outage ended.

Central Canada/North Central U.S.:
A very large mass of detatched smoke was visible earlier this morning
across central and eastern Canada. This smoke was likely due to a
combination of the fires in Alaska as well as the fires and blowing dust
observed last evening across Nevada, Idaho, and western Montana. The large
area of smoke covered Hudson Bay as well as northern Quebec, northern
Ontario, much of Manitoba, and Nanavut Provinces. It extended southward
to near the border with northwestern Minnesota. Smoke continues to be
entrained into circulation around upper low still present just south of
Hudson Bay.

Fires continue to burn mainly over eastern Alaska with some locally dense
smoke visible across Yukon-Koyukuk County. However, extensive cloudiness
is preventing the detection of additional areas of smoke which are likely
still present over a wider area.

Western U.S./Great Plains:
Morning visible imagery showed an area of smoke moving northeastward into
northern and eastern Montana, portions of the Dakotas, central Nebraska,
and also into Saskatchewan Province of Canada. This smoke is actually a
combination of smoke and blowing dust from fires burning across northern
and central Nevada, southern and central Idaho, and western Montana,
and blowing dust primarily from west central and northwestern Nevada.


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.
