DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1530Z August 23, 2006
Northern Rockies eastward through the Northern Plains: A large area of moderately dense to locally dense smoke stretches from the numerous source fires in central Idaho and western and southern Montana eastward. The smoke covers all of Montana, the Dakotas, northeast Wyoming, northern Nebraska and much of Minnesota. The smoke over the eastern extent is moving more to the southeast and is generally less dense than the smoke further to the west. The smoke is very dense in the valleys of Idaho and Valley counties in central Idaho from the fires in the Boise National Forest. A fire in southwest Johnson county Wyoming is producing a narrow moderately dense plume extending to the east-southeast. Washington/Oregon: Dense smoke from the large fire complex in the Okanagan National Forest is now moving to the southeast and covers portions of northeast Washington. The smoke is most dense over Okanagan county. A large fire along the southern border of Walla Walla and Columbia counties in southeast Washington is producing a moderately dense plume that extends to the northeast into northern Idaho. Fires over southeast Harney and northwest Malheur counties in Oregon are producing moderately dense plumes that are drifting to the northeast. Northern California: Fires in Siskiyou and Trinity continue to produce locally dense smoke in the valleys close to the fires and moderately dense smoke drifting to the southeast. Utah/Colorado: A fire in western Garfield county Utah has produced an area of thin smoke that covers portions of Piute and Sevier counties. An area of thin smoke also covers most of Moffat county in northeast Colorado and is slowly drifting to the southeast. Canada: A large area of thin smoke covers much of southern Nunavut Territory to Hudson Bay. Another broad area of somewhat denser smoke covers most of northeast Manitoba and northwest Ontario and western Hudson Bay. An area of smoke that originated from the fires in Idaho, Washington and Montana has been entrained into a weather system and covers southeast Alberta, much of Saskatchewan and southern Manitoba. The smoke is mixed with clouds over much of this area. Ruminski
