DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1730Z July 29, 2010

Central Canada:
Compared to yesterday the smoke plume across SE Northwest Territories,
SW Nunavut, and N Saskatchewan is not as dense and does not appear to be
as extensive in coverage.  The far southeastern extent of the plume has
continued to drift southward and is now seen over most of the western
and central Great Lakes including the states of Minnesota, Wisconsin,
and Michigan.  The primary source of the smoke is from numerous large
wildfires located along southeastern Northwest Territories and northern
Saskatchewan.

Western Canada:
Fires in NW BC are producing moderate to heavy dense smoke that can
be seen covering most of BC, SE Yukon Territory, W NW Territories and
central portions of Alberta.  The most dense smoke is seen over portions
of southern BC and west-central Alberta.  Some of the smoke appears caught
in an upper-level counterclockwise spinning circulation over central BC,
while the remaining smoke is slowing drifting eastward.

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.
