DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0300Z August 22, 2010

Southwestern Canada to Eastern Canada/Northeastern US/Middle Atlantic
States/ Western Atlantic/Canadian Maritimes/Labrador Sea:
Again, the situation with smoke was somewhat similar to what was described
in the narrative earlier today. Widespread cloudiness covers a good
portion of British Columbia and Alberta provinces which did hinder fire
and smoke detection in satellite imagery. However, smoke still could
be seen from the ongoing large fires in British Columbia Province of
southwestern Canada covering 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 northeastern Montana to the western Great Lakes
region and southward from there to the Central Plains. Thinner smoke
also extended eastward and southeastward from the Great Lakes region
to off the Northeast and Middle Atlantic coast, but cloudiness across
a good portion of the region prevented some details concerning the full
extent of the smoke. Embedded moderately dense to dense smoke extended
from British Columbia eastward to Ontario Province. Some of the thin to
moderately dense smoke also has spread northeastward around an area of
low pressure into central Canada around Hudson Bay. An additional rather
large area of thin density smoke was visible over portions of the Canadian
Maritimes and the Labrador Sea to near Greenland. Farther to the west,
cloudiness still covers the region where large fires existed recently
over northern Saskatchewan Province of west central Canada. Some of the
smoke in areas of central to eastern Canada, the Canadian Maritimes,
and portions of the Northeastern and Middle Atlantic regions of the US
may be composed at least partly of smoke from the Saskatchewan fires,
though it is believed to be mostly composed of smoke from the British
Columbia fires.

Wyoming/The Dakotas/Southeastern Montana:
A patch of thin leftover smoke could still be seen this evening moving
to the northeast over eastern Wyoming and into southeastern Montana and
the western Dakotas. This smoke was likely leftover from last evening's
larger fires over western Wyoming as well as a very large one over
southern Idaho near the Nevada border.

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.
