DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1600Z August 4, 2006.
Washington: The Tripod complex N and NE of Twisp, WA in the Okanogan Range is producing dense low level smoke that is moving due E and covers nearly all of Okanogan county E of the Chewuch River. California/Oregon: Large fires across NW California, such as: Hunter, Orleans, Bar, Kingsley, Panther and Uncle Complexes have produced a veil of thin to moderately dense smoke in the mid to upper levels of the troposphere. The smoke is being stretched out by upper level winds into a line that extends from NW Californi and offshore waters across central Oregon from the SW corner to the NE corner and is about 141km wide. The line then continues to thin both in width and density across N ID (covering Nez Perce and Shoshone counties) into NW MT, Saskatchewan to the southern tip of Lake Manitoba, where it becomes difficult to discern. Mid Atlantic coast: A large area of aerosol is seen emerging from the US East Coast ahead of the approaching cold front. The area extends from Nantucket Island SW to the Southern tip of the Delmarva and across the coastal flats of NC/SC/GA. The area seen is on average 350km wide (from NW-SE) and at its widest is more than 500km wide. North Central Canada: A narrow strip of smoke no more than 100km is caught in between stronger upper level streams... across N Manitoba from about 20km SE of Lake Hudson along the Ontario/Manitoba line to the 4 corners area of NW Territories, Nunavut, Manitoba and Saskatchewan. The smoke than expands in width, as it trapped under a upper level ridge, across most of the SE NW Territories (E of Great Slave Lake) and continental Nunavut. NW NW Territories: Smaller pockets of moderately dense smoke surround the Great Bear Lake from fires around the lake. One is SW of the Lake and is about 54km wide and extends 225km N to S. A second covers SE portions of the Lake and is 50km wide and extends 250km N to S...but at the NE portion of the Lake begins to extend NE to the Dolphin and Union Strait. Gallina
