DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1845Z September 1, 2009

Southern Canada/North and Central Plains/Midwest:
Remnant smoke was seen covering a very large portion of southern Canada,
the Northern and Central Plains, parts of the Midwest. Most of this
smoke is remnant from multiple large wildfires that have been burning
in southern British Columbia and southwest Alberta over the past few
days. Smoke stretched west to east from British Columbia to southwest
Quebec, as far north as central Hudson's Bay, and as far south as
Kentucky, Arkansas and Oklahoma. Areas of moderately dense to very dense
smoke were present, mostly along and north of the US/Canadian border with
one of the largest areas of very dense smoke northwest of Lake Superior.

Southern California to Colorado/Central to Southern Plains:
Remnant smoke continued to be pulled northeastward across the Southwestern
US by the strong upper low in place across Montana. The smoke spread
out as it reached eastern Colorado wrapping northward into the upper
low and also southeastward/southward over the Southern Plains. Most of
this smoke has originated from the large wildfires burning in Southern
California though other fires, such as those in Utah/northwest Colorado
yesterday, likely contributed some smoke as well. Moderately dense to
very dense smoke was present in two areas, one from the Utah/Nevada
border to northwestern Colorado and the other from western South Dakota
to eastern Colorado to the Oklahoma panhandle.

Western Oregon:
A small area of thin remnant smoke was present over northwest Oregon
this morning. This smoke was probably trapped in the valley and is
likely left over from local fires yesterday or possibly from the fires
in British Columbia.

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.
