DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1500Z September 21, 2010

Central/Southeastern US:
A large area of light smoke was identified through the central US.
This is likely remnant smoke from previous days fires through the
Mississippi Valley.  The smoke extends from southern Illinois and Indiana,
through eastern Arkansas, Missouri central Kentucky and Tennessee into
Mississippi, Alabama and western Georgia.  Once in Georgia, it is believed
to be more a mix of aerosols which extend north through the Carolinas
and into central Virgina; however, there may still be smoke mixed in
through this area.

Utah/Midwest:
The Twitchell Canyon fire continues to generate moderately dense to dense
smoke. Light smoke extends from the point source at the border of Beaver,
Sevier and Millard counties in Utah, through Colorado and southern Wyoming
into northern Kansas, the majority of Nebraska and southern South Dakota.
There are isolated patches of moderately dense smoke near the point
source in Utah and in Colorada.

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.
