DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0145Z July 17, 2007

Western and Central U.S./Southwestern Canada:
Wildfires in the Western U.S. caused a large arc of light to very dense
smoke. The smoke stretched from California northward to the northern
Rockies, across Montana and southern Canada then southward over the
great Plains. Areas of very dense smoke within the arc were observed over
Oregon/Washington, the Dakotas and Kansas. A large fire in Santa Barbara
County in California caused moderately dense smoke that fanned  out to the
south over the Santa Barbara Channel and northward to SW Fresno County.

Central Canada/ Upper Great Lakes:
Large fires in northern and central Manitoba Produced moderately dense
and dense smoke plumes that drifted to the south-southeast. The leading
edge of this smoke reached the Upper Great Lakes Region.

Northwest and Central Canada:
An area of thin and moderately dense smoke extended from NW Northwest
Territories to the fires in N Alberta in the vicinity of Lake Athabasca.

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.
