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. Brown
