DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1615 July 28, 2007
Pacific Northwest/Northern Rockies: Source areas along the Idaho/Oregon border near Hell's Canyon and the Idaho/Washington border south of Lewiston were creating an area of smoke that initially moves west but then curls around to the north and extends into northern Idaho. There are some areas of locally moderate to dense smoke. A broader area of light residual smoke from last evening covers much of southern Alberta, Montana and northwest Wyoming. Western Great Lakes Region: An area of light smoke is seen along the Minnesota/North Dakota border over the northern Red River Valley. The smoke is mainly on the Minnesota side of the border. The source is likely numerous fires that were burning yesterday in northwest Minnesota. Another area of smoke extends from southwest Ontario, across Lake Nippon and along the northern portion of Lake Superior and into northern Lake Huron. Much of this smoke is likely from large wildfires raging in northern Manitoba and Saskatchewan. Central Plains: A region of thin smoke was seen mixed with clouds across the central Great Plains stretching from northern Kansas across southwest Missouri and into northern Arkansas. Saskatchewan: Moderate to dense smoke plumes are detected over the large wildfires burning in northern Saskatchewan west of Reindeer Lake. The plume was lifting to the north. Yukon/Northwest Territory: Fires in the northern Yukon and northwest Northwest Territory were producing light to moderate smoke plumes that were mainly confined to the northern Yukon and border region of the Northwest Territory. Much of Alaska was cloud covered which prevented smoke detection. Ruminski
