DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0300Z July 31, 2010

Western/Central Canada/Northern US Plains/Great Lake region:

A large and expansive area of moderate to dense smoke covered a large
section of western and central Canada and extended into the north
central part of North Dakota. Smoke this evening remained stretched from
the Yukon Territory and northern British Columbia across the Northwest
Territories and western Nunavut, southeastward over parts of Saskatchewan,
Manitoba, Hudson Bay, Ontario, the northern Great Lakes region, and
western Quebec. The large area of smoke originated from three areas of
concentrated fire activity; northern Saskatchewan and the southeastern
portions of the Northwest Territories and northwestern British Columbia
and the southern Yukon Territory.

Another area of moderately dense smoke over portions of southern British
Columbia and Alberta was the result of numerous fires burning in south
central British Columbia and a few in north central Washington state. By
this evening, much of this secondary area of smoke had started to merge
with the larger mass of remnant smoke over Canada.

Northeast Canada:
A plume of aerosols believed to be remnant smoke from the wildfires in
western/central Canada was still seen this evening being swept off the
coast of Labrador and wrapped into an upper low over the Arctic.

Mid-Atlantic/Northeast US:
A band of aerosols believed to be remnant smoke transported from the
Canada fires southeastward across the Great Lakes yesterday was continued
to move eastward this evening further from the Eastern Seaboard. The
northern end of this aerosol stretched over Nova Scotia.

Northwestern US/Southern Albera/ Southern Saskatchewan:
A quick moving storm system was seen transporting a band of aerosol along
with it to the east. Some of this aerosol over east Montana, southwest
Saskatchewan, and southeast Alberta is believed to be smoke from fires
in Washington yesterday though the rest across parts of Oregon, Idaho,
Washington, and northwest Montana may be blowing dust or some other
unknown aerosol.

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.
