DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1700 UTC August 4, 2007

Western U.S and Southern Canada:
Persistent fires in northwestern United States and southeastern British
Columbia are contributing to the dense and very dense smoke from
northern Oregon/northern Idaho across Montana to southern Saskatchewan
and Manitoba. The area of smoke becomes thinner and turns southward over
the Northern Plains and the Upper Mississippi Valley. Risidual smoke from
the large fires in Santa Barbara County in California extends northward
to central California and western Nevada.

Central and Eastern United States:
The very large area of smoke and haze from the fires in the Northwest
and British Columbia covers much of the central U.S.
, the Southeast and the Middle Atlantic. During the morning hours the
most dense smoke and haze stretched from the Mid-Atlantic to southern
New England. A plume of dense smoke from the fire in N Luce County in
Michigan is drifting northward over eastern Lake Superior.

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.
