DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0330Z August 20, 2009

North Atlantic:
Off the Mid-Atlantic and Northeastern US coastlines, light haze/aerosols
were seen continuing to drift east and northeastward throughout the
day. This haze extended northeastward just along the coast of Nova Scotia
and across southern Newfoundland.

Washington/Montana/Idaho/British Columbia:
A fairly large area of moderately dense to dense smoke remained over
much of northern/eastern Washington, north Idaho, extreme western parts
of Montana, and southern British Columbia including most of Vancouver
Island. By this evening, thin smoke had spread out across a larger
part of western Montana, central Idaho, and southeast Washington. This
smoke was caused mostly by a large wildfire burning in southern British
Columbia, though other smaller fires around the Pacific Northwest may
have contributed aerosols as well. As the large active fire mentioned
above continued to burn today, another round of fresh dense smoke began
to form over southwest British Columbia.

California/Oregon/southwest Idaho:
Thin smoke appeared in this evening's GOES-12 satellite imagery covering
most of the state of California, large portion of Oregon, and part of
southwest Idaho. Active fires in California/Oregon were adding additional
aerosols but most of the smoke was leftover from yesterdays fires in the
same areas. Some moderately dense smoke was present over the southern
part of the Central Valley in California.

New Mexico/Texas/Oklahoma/Kansas:
Thin remnant smoke was seen in GOES-12 visible satellite imagery
stretching across southern/eastern New Mexico, the Texas and Oklahoma
panhandles, and southwest/central Kansas. This smoke is believed to be
leftover from yesterdays fires in Arizona and New Mexico; many of which
were still actively burning today.

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.
