DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0215Z AUGUST 14, 2008


Northern California:
Several fires in the northwestern region of the state, in Trinity, Shasta,
Del Norte, and Siskiyou counties, are producing moderately dense to dense
smoke plumes. These plumes were moving to the southwest earlier today,
however they are now advancing towards the northwest. In addition, light
smoke covers most of the northern to central region of the state north
of 37N.

Northwest US/Upper Plains/Canada:
A narrow band of SO2 around FL310 stretches east across southern Oregon,
southern Idaho, northern Utah, souther Wyoming, western Nebraska, and
then bends northward/northwestward into the Dakotas, and eastern Montana.
Furthermore, fires in northern Canada around the Great Slave Lake are
producing immense amounts of smoke. Lighter smoke is being pulled down
around a low pressure system, situated  over southern Saskatchewan, from
northern Alberta southward into eastern Montana and North Dakota. Some
residual SO2 may also be mixed in with the smoke, especially in parts
of North Dakota and southern parts of Canada.

Canada:
Residual light smoke from yesterday is still found over Hudson Bay. In
addition, because clouds broke up this afternoon, several plumes over
northern Saskatchewan are producing moderately dense to dense smoke
plumes. These plumes are currently moving to the north and northwest
into the southern areas of the Northwest Territories.

Idaho:
In Elmore County, a moderately dense smoke plume is heading to the
southeast and extends out 40km. Another moderately dense smoke plume,
along the border of Idaho and Valley counties, is advancing east into
extreme western Montana.

Washington State:
A moderately dense smoke plume in Okanogan County in the north-central
region of the state, is heading to the south and extends out 75-100km.

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.
