DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0230Z June 25, 2007
California/Nevada: A wildfire developed rapidly this afternoon near South Lake Tahoe in eastern California producing a very large mass of dense smoke which spread quickly to the northeast reaching northeastern Nevada just prior to sunset. Another large wildfire burning in or near the Tehachapi Mountains in southern Kern County of southern California was emitting a moderately dense to dense smoke plume which moved as far to the northeast as Clark County in southern Nevada. Utah/Wyoming: A long narrow moderately dense to dense smoke plume from a fire just west of Provo in central Utah moved to the northeast into west central Wyoming during the late afternoon and evening. The smoke plume affected the Salt Lake City region as it moved to the northeast. A second fire also in Utah County to the southeast of Provo was also producing smoke which moved to the northeast, but this smoke was mainly of a thin to perhaps moderately dense nature. Alaska/Yukon/Northwest Territories/Northeast British Columbia/Northern Alberta/Northern Saskatchewan: More widespread cloudiness was present across the Kenai Peninsula today, preventing detection of any fires or smoke there. Most of the smoke and fires detected today were located from the Alaskan-Canadian border eastward across Yukon Province and the Northwest Territories in northwestern Canada as well as in northern Alberta, just west of Lake Athabasca. A large mass of smoke of varying density was present across much of the Yukon and the western portion of the Northwest Territories extending southward to the far northern portions of British Columbia, Alberta, and Saskatchewan. The largest fires were located in north central Yukon Province, in the Northwest Territories around 100 miles to the west of Great Bear Lake, and in northern Alberta Province just west of Athabasca Lake. The smoke was moving mainly in a northerly direction initially from many of the fires, but began to turn more to the northeast and east as it moved farther to the north. Quebec: Several fires were detected scattered across south central, southwestern, and western Quebec Province. A few of them were producing dense smoke plumes which moved mainly in a southeasterly direction. JS
