DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0300Z September 24, 2010

Lower and Middle Mississippi Valley:
A tremendous number of what were believed to be mostly agricultural fires
were detected across the Lower and Middle Mississippi Valley region from
northeastern Louisiana to southeastern Missouri. Many smoke plumes were
also seen in visible satellite imagery during the afternoon and early
evening which moved to the north and combined to form a larger mass of
thin density smoke.

South Central Oregon and Eastern Idaho:
Swaths of blowing dust were visible late this afternoon moving to the
northeast from point sources located in Jefferson County of southeastern
Idaho as well as Lake County of south central Oregon. The blowing dust
originating from Lake County in south central Oregon also combined with
smoke plumes from fires farther to the southwest in southern Oregon and
northern California.

For graphical information on other smoke plumes analyzed today, please
refer to the web pages 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.
