DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0245Z August 29, 2009

California:
Cloudiness continues to interfere significantly with smoke detection
especially over central and northern California. Through a few breaks in
the clouds, a moderately dense to dense smoke plume could be detected
moving to the north from the large fire in northern Mariposa County
of east central California. The extent of the plume though could not be
determined in satellite imagery because of the clouds. Across west central
and southern California, a large area of mainly thin smoke could be seen
primarily along the coast and offshore during the late afternoon. This
smoke was likely from the fires burning in Monterey County as well
as the ones farther down the coast in southern California. Closer to
the actual fires, limited information concerning the smoke could be
determined in satellite imagery due to the cloudiness. Through a few
breaks in the clouds, dense smoke was visible moving to the northwest
from the large fire in central Los Angeles County. Even farther to
the south, a number of large fires burning in northwestern Baja were
emitting a mass of moderately dense to dense smoke which was moving in
a northwesterly direction. Some of this smoke appeared to make it into
San Diego County and especially right along and just offshore of extreme
southwestern California.

Northwestern US:
More cloudiness moving inland over much of Washington and Oregon greatly
limited smoke detection in satellite imagery. A patch of leftover detached
thin to moderately dense smoke from the fire in northern Grant County of
northeaster Oregon continued to be visible this afternoon in satellite
imagery. This batch of smoke was moving to the east into western and
central Montana. The leading edge of thin smoke from huge fires burning
in southern British Columbia of southwestern Canada was also spreading
southeastward into northern and central Montana.

Southwestern Canada:
A number of large fires continue to burn across southern British Columbia
producing significant amounts of moderately dense to dense smoke initially
moving to the northeast. A large mass of moderately dense to dense smoke
from yesterday afternoon's flare up continued to be observed in satellite
imagery this afternoon moving to the east over the northern two-thirds
of Alberta Province. The thinner leading edge of the smoke was moving
to the southeast into Montana.

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.
