DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1530Z JULY 25, 2008


Northern California:
Wildfires in the northern third of the state are producing moderately
dense to dense smoke in the Sacramento Valley that is then being pulled
north and trapped west of the Cascade mountain range all the way into
central Washington state. Some of the smoke is also drifting south
across the Napa Valley and San Fransisco Bay where it joined up with
smoke from the fire in Monterey Country that then becomes mixed in with
marine clouds that made it hard to follow.

Northern Plains:
Residual light smoke of unknown origin could be seen from SE Montana
southeast to southeastern S. Dakota.

Canada:
A fire on the north shore of Great Slave Lake west of Yellowknife is
spreading smoke across the lake were it joins with smoke from a large
fire west of Fort Smith in the Northwest Territories that then moves east
and southeast toward and across Lake Athabasca where it combines with
plumes of thick smoke from numerous large fires in northern Saskatchewan.
This pool of thick smoke is the stretched north to Queen Maud Gulf in the
Nunavut Provence and southeast across Lake Winnipegosis, Lake Manatoba,
the city of Winnipeg to over the NE corner of N. Dakota and NW Minnesota.

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.
