DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0315Z August 21, 2010

Southwestern Canada to Eastern Canada/Northeastern US/Western Atlantic:
The situation is very similar to the narrative written earlier
today. Smoke from the ongoing large fires in British Columbia Province
of southwestern Canada continues to cover a very large area with thin
density smoke extending from British Columbia eastward over much of south
central Canada to southeastern Canada. Some of the leading edge of the
thinner smoke had also moved over a portion of the northern tier of the
US, especially over the region from Montana to the Dakotas and Minnesota
as well as northern New England. Embedded moderately dense to dense smoke
extends from British Columbia eastward to western Ontario Province. Some
of the moderately dense smoke also has spread northeastward around an
area of low pressure into central Canada around Hudson Bay. An additional
large swath of thin smoke likely leftover from the British Columbia fires
extends from the Great Lakes region eastward and southeastward over the
Middle Atlantic states and a portion of the Northeast including southern
New England to off the coast. The area extends slightly more to the south
than earlier today, covering most of North Carolina into northern South
Carolina. Cloudiness covers the region where large fires existed recently
over northern Saskatchewan Province of west central Canada. Some of the
smoke from Saskatchewan Province southeastward to northern New England
may have some contribution from the Saskatchewan fires.

Northern California/Oregon/Idaho/Montana/Western Wyoming:
A swath of very thin smoke was visible late this afternoon/early this
evening moving northeastward and inland over northern California,
a good portion of Oregon, central Idaho, and into Montana. This thin
smoke was believed to be leftover from the British Columbia fires and
was transported southward over the Pacific and eventually eastward
and inland. Other fires with smoke plumes were scattered over the this
region as well including a very large dense plume moving to the northeast
from a fire along the Nevada-Idaho border. See the web links below for
additional graphical information on these fires.

THE FORMAT OF THIS TEXT PRODUCT IS BEING MODIFIED. IT WILL NO LONGER
DESCRIBE THE VARIOUS PLUMES THAT ARE ASSOCIATED WITH ACTIVE FIRES. THESE
PLUMES ARE DEPICTED IN VARIOUS GRAPHIC FORMATS ON OUR WEB SITE:

JPEG:   http://www.osdpd.noaa.gov/ml/land/hms.html
GIS:    http://www.firedetect.noaa.gov/viewer.htm
KML:    http://www.ssd.noaa.gov/PS/FIRE/kml.html

THIS TEXT PRODUCT WILL CONTINUE TO DESCRIBE SIGNIFICANT AREAS OF SMOKE
WHICH HAVE BECOME DETACHED FROM AND DRIFTED SOME DISTANCE AWAY FROM THE
SOURCE FIRE, TYPICALLY OVER THE COURSE OF ONE OR MORE DAYS. IT WILL ALSO
STILL INCLUDE DESCRIPTIONS OF BLOWING DUST.

ANY QUESTIONS OR COMMENTS REGARDING THESE CHANGES OR THE SMOKE TEXT
PRODUCT IN GENERAL SHOULD BE SENT TO SSDFireTeam@noaa.gov

 


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.
