DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0315Z August 3, 2010


Alaska/Northwestern Canada:
Thin to locally moderately dense smoke continued to be observed across
northern Alaska and the southern Arctic Ocean extending southeastward
into northwestern Canada. An additional swath of moderately dense smoke
was visible moving southward from the Northwest Territories toward Great
Slave Lake. Some of this smoke was likely due to fires scattered across
central and east central Alaska as well as northwestern Canada. However,
it is possible that smoke from the fires in Russia was also being
transported across the Arctic into this region. Another band of smoke
which is likely from the Russian fires was seen in visible satellite
imagery this evening through breaks in the clouds moving to the northeast
across the Pacific between 44N170W and 49N161W. The smoke may extend even
farther to the northeast, but cloudiness prevented additional information
from satellite imagery.

Central Canada:
The numerous fires centered mainly in northern Saskatchewan Province
continue to emit moderately dense to dense smoke which moved primarily
to the east across central Canada to Hudson Bay.

British Columbia/Alberta/Saskatchewan/Manitoba/Northwestern and North
Central US:
Dense smoke continued to emanate from the fires in British Columbia
of southwestern Canada and move in multiple directions. Some of the
moderately dense to dense smoke had spread southward into Washington,
Oregon, northern Idaho, and northwestern Montana as well as southern
British Columbia and southern Alberta provinces. Thinner smoke from
these fires had also moved southward just off the west coast and back
inland over northern California, just north of the San Francisco Bay
area. Additional thinner smoke had moved eastward and northeastward over
the remainder of Montana and North Dakota into northwestern Minnesota
as well as a good portion of Saskatchewan Province and Manitoba
Province. Some of this smoke had also combined with the smoke from the
Saskatchewan 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.
