DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0115Z July 25, 2007

Central (from the Rockies to the Appalachians)/Eastern Canada:
The numerous large wildfires in the western US and over central Canada
have produced an incredible amount of smoke over the past several
days. The smoke from these areas has merged and covers much of the
area between the Rockies and the Appalachians in the US and much of
southeast Canada from Manitoba to central Quebec. The most dense smoke
is seen across northern Ontario and extends east across southern Hudson
Bay and covers all of James Bay and reaches to west central Quebec. A
portion of this dense smoke is being drawn into the circulation of an
upper level cyclone over the Ohio Valley and is drifting across eastern
Lake Superior and the upper peninsula of Michigan.

Much of the western US where the fires have been raging is cloud covered
today and is precluding smoke detection for most of the fires. One area
is visible though along the northeast Oregon/west central Idaho border
where long running fires are producing locally dense smoke in and around
the Hell's Canyon area.

A large area of light to moderate smoke is seen across the northern
Plains from Montana across the Dakotas and into western Minnesota. A
separate patch of residual mainly light smoke is seen from eastern
Arkansas stretching to the east northeast across much of Kentucky and
Tennessee. This area of smoke is likely also mixing with regional haze.

Another patch of mostly light smoke is evident from central Oklahoma
across eastern Kansas and into northwest Missouri. This smoke is likely
the result of several days with large numbers of agricultural burns seen
over central Kansas and Oklahoma.

California:
A fire in central Santa Barbara county is producing a plume of moderately
dense smoke that is moving to the south across the Santa Barbara channel
and over the Channel Islands. Dense smoke from fires in northwest
Siskiyou county is drifting to the northeast and just reaches across
the Oregon border.

Alaska/Northwest Territory:
A small fire along the north slope southeast of Umiat is producing a
plume of light to moderate smoke that is mainly fanning out and drifting
to the south. A larger fire in the Northwest Territory near Fort Good
Hope is producing a moderate to dense plume of smoke that is moving to
the southeast.

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.
