DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0245Z JUNE 18, 2008

Middle Atlantic and Southeastern US:
Fires continue to burn over southeastern Virginia and northeastern North
Carolina resulting in moderately dense to locally dense smoke which moved
primarily in an eastward direction during the day and across the coastal
regions of southeastern Virginia and northeastern North Carolina and
offshore. Lingering thin smoke from these fires mixed with haze from
other atmospheric pollutants was visible along and off the southeast
coast from northeastern Florida to eastern North Carolina.

Middle and Lower Mississippi Valley:
An incredible number of what are believed to be primarily agricultural
fires were detected over southeastern Missouri, eastern Arkansas, and
northwestern Mississippi. Cloudiness interfered with smoke detection
for a good part of the day, but some breaks in the clouds late in the
afternoon revealed numerous smoke plumes moving in a southerly direction
particularly from the fires in southeastern Missouri and northeastern
Arkansas.

Central and South Central Canada/North Central US:
A large mass of thin to moderately dense smoke detached from the ongoing
fires in northern Saskatchewan Province  in Canada was visible fanning
out to the north and to the south-southeast.  The smoke extended well
up into north central Canada, likely beyond the extent of the GOES
satellite coverage.  It also stretched southeastward over Manitoba
and western Ontario provinces to eastern North Dakota, Minnesota,
Wisconsin, northeastern Iowa, northern Illinois, southwestern Michigan,
and northwestern Indiana.  In addition, the fires appeared to flare up
again this afternoon resulting in moderately dense to dense smoke which
moved mainly in an eastward direction, although cloudiness interfered
with smoke viewing.

California/Nevada/Utah:
The large fire in central Monterey County of west central California
continued to burn through the day producing thick smoke which fanned out
as it spread southeastward from the fire. A larger area of thin smoke
extended northeastward from the fire to west central Nevada, including
the Lake Tahoe region. Even farther to the east, possible detached thin
smoke from this fire was visible across portions of northern Utah and
southwestern Wyoming.  Thin to moderately dense smoke fanned out as
it moved eastward from a fire in southwestern Tehama County of north
central California.

Oregon:
Moderately dense to locally dense smoke also fanned out as it moved to
the east from a fire which flared up during the afternoon over central
Klamath County of south central Oregon.  Thin to moderately dense smoke
moved both to the northeast and to the southeast from a fire in western
Douglas County of west central Oregon.

Washington/Oregon:
A possible thin streak of blowing dust was visible moving to the northeast
from a source region near the Columbia River along the WA/OR border near
the intersection of Walla Walla, Umatilla, and Benton Counties.

West Central Nevada:
In addition to the thin smoke present from the California fires, some
localized blowing dust was also being kicked up by gusty westerly winds
from source regions in west central Nevada.

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.
