DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0200Z August 5, 2006.
California/Oregon/Idaho/Washington/Montana/southwestern and south central Canada: The Tripod complex north and northeast of Twisp, Washington in the Okanogan Range is still producing dense low level smoke that is moving due east and covers nearly all of Okanogan county east of the Chewuch River. Large fires across northwestern California, including Hunter, Orleans, Bar, Kingsley, Panther, Mendocino and Uncle Complexes have produced a veil of moderately dense to locally very 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 has connected with the smoke from Washington and extends from northwestern California and offshore waters across central Oregon from the SW corner to the northeastern corner and is about 141km wide. The complex smoke then continues to extend across almost the whole of Washington and across northern Idaho (covering Nez Perce and Shoshone counties) into northwestern Montana, Saskatchewan to the southern tip of Lake Manitoba. 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 the southern New Jersey coast southwest to the southern tip of the Delmarva and across the coastal flats of the Carolinas and Georgia. The area seen is on average 350km wide (from NW-SE) and at its widest is more than 500km wide. Louisiana/northeastern Texas: Several narrow plumes of mainly thin smoke were seen across this region during the afternoon and early evening. The plumes were all moving to the northeast or north and were mainly less than 50 km long. NW Canada: Smaller pockets of moderately dense to locally dense smoke surround the Great Bear Lake from fires around the lake, which is moving north toward the Arctic Circle. A thin plume of smoke seen in the evening GOES WEST imagery is swirling around northern Yukon Territory panhandle area. Zhong
