DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1630Z August 25, 2005
Northern and Western Canada: Moderately dense smoke from the Alaskan fires extends across the Islands of the NW Territory to NW Baffin Island. All of the smoke is contained N of 65N, except for an area of thin smoke that extends south along 110W into a well defined cyclone over South-central Saskatchewan. Moderately dense smoke can be seen along the northern and western periphery of the cyclone, with the most dense further north nearer to the orginal source in AK. The smoke can be seen swirling around in an area from N Saskatchewan across E Alberta south into NW MT along the eastern slopes of the Rockies. Smoke most likely exists across most of S Saskatchewan as well, but clouds near the cyclone center make it difficult to see. Intermountain West: A swath of thin smoke 140km wide extends from the ID/NV line near Jackpot, NV to the ENE near Buffalo SD and is focused along the convergent band S of the Saskatchewan cyclone. California/Nevada: A dense plume of smoke from the Harding fire in E California is 19km wide and extends NNE to just N of Pyramid Lake then moves ENE across the southern Black Rock desert and S Humbolt county to near Midas,NV in W Elko county. Washington: Resuspended volcanic ash due to high winds near Mount St. Helens is causing a moderately dense plume to the NW about 60km and is about 17km wide. Gallina
