DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1600Z August 4, 2006.


Washington:
The Tripod complex N and NE of Twisp, WA in the Okanogan Range is
producing dense low level smoke that is moving due E and covers nearly
all of Okanogan county E of the Chewuch River.


California/Oregon:
Large fires across NW California, such as: Hunter, Orleans, Bar,
Kingsley, Panther and Uncle Complexes have produced a veil of thin to
moderately dense smoke in the mid to upper levels of the troposphere.
The smoke is being stretched out by upper level winds into a line that
extends from NW Californi and offshore waters across central Oregon from
the SW corner to the NE corner and is about 141km wide. The line then
continues to thin both in width and density across N ID (covering Nez
Perce and Shoshone counties) into NW MT, Saskatchewan to the southern
tip of Lake Manitoba, where it becomes difficult to discern.

Mid Atlantic coast:
A large area of aerosol is seen emerging from the US East Coast ahead
of the approaching cold front.  The area extends from Nantucket Island
SW to the Southern tip of the Delmarva and across the coastal flats
of NC/SC/GA.  The area seen is on average 350km wide (from NW-SE) and
at its widest is more than 500km wide.

North Central Canada:
A narrow strip of smoke no more than 100km is caught in between stronger
upper level streams... across N Manitoba from about 20km SE of Lake Hudson
along the Ontario/Manitoba line to the 4 corners area of NW Territories,
Nunavut, Manitoba and Saskatchewan.  The smoke than expands in width, as
it trapped under a upper level ridge, across most of the SE NW Territories
(E of Great Slave Lake) and continental Nunavut.

NW NW Territories:
Smaller pockets of moderately dense smoke surround the Great Bear Lake
from fires around the lake.  One is SW of the Lake and is about 54km
wide and extends 225km N to S.  A second covers SE portions of the Lake
and is 50km wide and extends 250km N to S...but at the NE portion of
the Lake begins to extend NE to the Dolphin and Union Strait.

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.
