DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0045Z UTC August 16, 2007

Eastern US/Coastal Waters/Nova Scotia:
It may be easier to describe areas that are NOT covered by smoke/haze
from the Idaho/Montana fires!
Much of the Great Lakes is cloud covered with high cirrus and some deeper
convection, but on the periphery of the northern side across N WI, UP
of MI, northern LP of MI is covered with thin smoke that is caught in
the jet streak coming out of Canada.
Moderately dense smoke ahead of cold front extends from the southern
coastline of New Foundland across E Nova Scotia, to Cape Cod where the
front begins to flatten out east-west across New England...though the
smoke wedge also begins to widen from Cape Cod almost to Bermuda covering
most of the Atlantic from Cape Cod to 35N70W where easterly flow begins
to turn the more stagnant area of smoke and more haze/pollution toward
the west.  Continuing from 35N70W, to Miami, Florida across to Ft. Myers
to Mobile, AL, to Natchez, MS north along the Mississippi River to the
Bootheel of MO where a pocket of moderate to dense haze/smoke extends
further west to 92W, then to South of St. Louis, MO across S IL, IN,
OH where the cloud cover becomes dense again, with a high likelihood of
smoke over E OH, all of PA, S NY, S CT back to Cape Cod.
A few pockets of cleaner air can be seen E and SE of the Appalachians
across N GA, SC and E NC...but a narrow strip of very dense smoke that
is moving SE extends from Bristol, TN to Norfolk, VA out to 40N68W on
the leading edge of an airmass that was over the Upper Midwest over the
last 2 days. It has subsequently sheared out, though concentrated into
this narrow 50-100km wide strip.

Idaho/Montana/Upper US Great Plains:
Every large fire across W MT, Idaho (mainly Salmon River Mtns), and
Columbine 1 fire in Yellowstone NP has a extremely dense plume extending
due east from it at least 50km with an average width of 25km. The plumes
meld into a larger area that mixes with yesterday's and this mornings less
dense (though still dense) smoke around 108W.  The smoke then extends in
a dense plume across SW MT (S of 47.5N), NE WY covering all of SD and the
southern 1/3rd of ND turning ESE covering the extreme SW corner of MN,
NW Quarter of IA, and NE NE (N of 41N) and E of 100W.

Washington/Oregon:
The Domke Lake fire is covered with clouds making detection of smoke
very difficult at this time, however a small fire in NW Yakima county
near Goose Prairie is producing moderate smoke that is moving NW up the
river valley into ext NE Pierce county.

The WSA Fire complex producing a narrow 16km wide line of moderately
dense smoke that extended due north along the spine of the mtns as far as
West Central Kittitas county, WA!  As the day progressed the near fire
environment lead to an expansion of the smoke area in all directions
(making a nice ring) over NE Jefferson, E Marion, E Clackamas, and SW
Wasco counties.

California into Nevada:
Smoke from the Zaca fire (last night's emissions) extends due north
into NV covering all of W NV from OR and CA boarders east to 118W, then
over CA from Lake Tahoe to the Channel Islands to Santa Monica along the
Ventura/Los Angles county line across the LA county/Kern county line to
San Bernadino county line then Neward into the Mojave desert to around
the NV/CA line near 37N.  The extremely/convectively dense smoke from
today's intense burning has been drifting in all directions and currently
covers all of Ventura county, Santa Cruz island, E half of Santa Barbara
county, SE San Luis Obispo county, a 30km wide line centered along the
LA/Kern county Line and the Western 2/3rds of Kern county with a small
extension of dense smoke moving due north along the Kings/Tulare county
line to around southern Fresno area.

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.
