DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THRU 0200Z JULY 24, 2005
Central Canada to Southeastern Canada: Cloudiness is still greatly hampering smoke detection. However through breaks in the clouds it is apparent that the smoke seen earlier today and yesterday has decreased. In particular no smoke is seen in Quebec and the remaining smoke in Ontario is more diffuse than previously. This smoke is believed to have originated in the fires burning in Alaska and to a lesser extent far western Canada. Alaska and Western Canada: A large, fairly dense band of smoke continues to extend from the Yukon through central Alaska to the Bering Sea. The smoke covers about a third of Alaska. Separate smaller areas of smoke are found south of Great Bear Lake. Western and central U.S.: Fires in Nevada, Arizona, Utah and Colorado are less numerous tonight and the accompanying smoke has also decreased. There is a small area of quasi-stationary diffuse smoke in northwestern Arizona and southwestern Utah. There are fairly large and dense smoke plumes in northern Utah, south central Idaho, and along the Washington/Oregon border. There are also two possible areas of very diffuse smoke mixed with haze, one in eastern Utah and the other in South Dakota.
