DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0300Z August 08, 2009

Alaska/Canada:
A large and very dense smoke plume continues to be analyzed over from the
Bering Strait/Alaska and through a large portion of Canada.  The smoke
continues to originate from a large number of wildfires analyzed over
sections of Alaska and the Yukon although cloud cover has somewhat
limited that to some extent this evening.  This evening the main axis
of the plume extended from the Bering Strait through central Alaska and
then to the southeast through northern portions of Alberta, Saskatchewan,
Manitoba and then through the southern portions of Hudson Bay.  An earlier
extension of the plume seen over southern Ontario and Quebec was much
more difficult to detect on evening satellite imagery.

British Columbia/Washington:
A significant number of wildfires continue over a good portion of British
Columbia and this continues to produce a rather large and dense smoke
plume over most of British Columbia and was seen dropping southwest and
covered sections of Washington before being obscured by mid and high
cloud cover.

More information on the areas of smoke described above as well as others
can be found at the locations listed below.

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.
