DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0400Z UTC August 12, 2007

Northwest and Northcentral U.S. and adjacent regions of extreme southern
Canada:
The most numerous and largest smoke producing fires are in Idaho and
western Montana, but fires in northern Oregon, southern and eastern
Washington, and northwestern Wyoming are also contributing smoke.
Light to moderate to dense smoke covers most of eastern and central
Washington, northeastern Oregon, extreme southeastern British Columbia,
southern Alberta, almost all of Idaho and Montana, northwestern Wyoming,
almost all of North Dakota, northern Minnesota and part of southwestern
Ontario.  The largest area of dense smoke is in central Idaho and western
Montana although fires in southeastern Idaho and northwestern Wyoming
are also producing dense smoke.  Smoke is moving toward the east or
northeast but the continual new smoke emissions are keeping the overall
area of smoke mostly stationary.

California and Nevada:
Moderate to dense smoke from the large persistent fire in Santa Barbara
extends toward the northeast.  The Santa Barbara fire's smoke becomes
mixed with moderate smoke from the fire near the Kings/Fresno/Monterey
County border region first observed yesterday evening. The smoke continues
moving toward the north northeast, becoming mostly light as it moves
into western and northern Nevada and then joins with the huge area of
smoke in the northwest.

Southeastern and Southcentral U.S. and adjacent waters:
Mostly light smoke originally from the fires in Oregon, Idaho and
Montana is mixed with haze.  The smoke/haze mix occurs in a swath that
covers eastern Texas, moves across the northern Gulf of Mexico and into
northern Florida, southern Alabama and most of Georgia, and then continues
northward into the Carolinas and nearby Atlantic Ocean. Moderate smoke
occurs mostly over northern Florida and coastal Georgia and coastal South
Carolina.  The overall area of smoke is quasi-stationary.  In addition to
this large area of smoke, there are several individual smoke plumes in
Alabama, Mississippi, and Arkansas that extend southward.  These smoke
plumes are light to moderate except for the moderate to dense plume in
Bibb County, Alabama that extends well into northern Dallas County.

Ohio and Kentucky:
Throughout the day areas of light smoke have moved eastward through
Ohio and Kentucky.  These are also a remnant of the fires in Oregon,
Idaho and western Montana.

Michigan:
Any smoke from the fire in Luce County has been difficult to observe in
satellite imagery today due to cloud cover but this large fire is likely
to be producing smoke.

 


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.
