DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0230Z UTC August 11, 2007

Oregon:
A large fire over western Jefferson County is producing a very dense
smoke plume which is moving to the east across much of the northern
third of Oregon. Slightly less dense smoke likely at a lower level was
also observed fanning out to the south and southeast from this fire.

California:
The fire in Santa Barbara is still raging and is responsible for an
extremely large dense smoke plume which was generally moving to the north
but also fanning out to the northwest and west. The dense smoke appeared
to reach close to the Fresno area just prior to sunset. Thinner smoke
from this fire was also noted spreading to the northeast and reaching
as far as east central Nevada. Additional fires were detected this
afternoon and evening over eastern Tehama County in northern California
and eastern Amador County in east central California. Both of these
fires were emitting moderately dense to locally dense smoke which moved
in a northeasterly direction. Late in the day, another fire appeared
to start near the Monterey-Kings-Fresno County border region but little
details on the smoke plume could be known from satellite data since it
was covered by the dense smoke from the Santa Barbara County fire.

Idaho/Montana/Wyoming:
The very large wildfires continue to burn in central Idaho and western
Montana resulting in even more dense smoke which moved to the northeast
during the day. Much of central Idaho and a good portion of Montana were
covered in moderately dense to locally dense smoke. Several additional
fires were noted in the northern Wyoming County of Sheridan as well as the
northwestern Wyoming counties of Park and Teton. These fires were likely
producing moderately dense to locally dense northeastward moving smoke
plumes but cloudiness in the region did prevent some details concerning
the smoke to be made.

Southern Canada/Northern and Central US:
Smoke from the western fires (particularly from the Idaho and Montana
fires) was visible across a very large region including south central
Canada, the Northern Plains, the Upper and Middle Mississippi Valley, the
Great Lakes region, and even at least part of the Ohio Valley. Moderately
dense to even locally dense smoke within this large region was noted
over northern North Dakota, northern and central Minnesota, and southern
Canada.

Northeastern Gulf of Mexico/Southeastern US:
An elongated swath of haze was still observed extending from the
northeastern Gulf of Mexico, across northern Florida and southern Georgia,
to along and off the Carolina coast. This region of haze may still contain
some remnant smoke from the western wildfires which became trapped under
the upper level high pressure ridge several days ago.

Kansas/Oklahoma:
A cluster of what are believed to be primarily agricultural type fires
in south central Kansas and north central Oklahoma were occasionally
producing thin puffs of smoke which moved mainly in a northerly direction.

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.
