THROUGH 1700 UTC August 4, 2007
Western U.S and Southern Canada: Persistent fires in northwestern United States and southeastern British Columbia are contributing to the dense and very dense smoke from northern Oregon/northern Idaho across Montana to southern Saskatchewan and Manitoba. The area of smoke becomes thinner and turns southward over the Northern Plains and the Upper Mississippi Valley. Risidual smoke from the large fires in Santa Barbara County in California extends northward to central California and western Nevada. Central and Eastern United States: The very large area of smoke and haze from the fires in the Northwest and British Columbia covers much of the central U.S. , the Southeast and the Middle Atlantic. During the morning hours the most dense smoke and haze stretched from the Mid-Atlantic to southern New England. A plume of dense smoke from the fire in N Luce County in Michigan is drifting northward over eastern Lake Superior. Brown
