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.

Unless otherwise indicated:
  • Areas of smoke are analyzed using GOES-EAST and GOES-WEST Visible satellite imagery.
  • Only a general description of areas of smoke or significant smoke plumes will be analyzed.
  • A quantitative assessment of the density/amount of particulate or the vertical distribution is not included.
  • Widespread cloudiness may prevent the detection of smoke even from significant fires.
