DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1800Z March 21, 2011

Ohio Valley/Mid-Atlantic Region/Southeast/Gulf of Mexico:
The NWS Air Quality Forecast Guidance at the following site...
http://www.nws.noaa.gov/aq/sectors/conus.php   is indicating leftover
smoke across portions of the Ohio Valley, the Mid-Atlantic region, the
Southeast, and offshore over the far western Atlantic and the eastern
Gulf of Mexico. Visible satellite imagery does show a bit of aerosol
in some of these areas though cloudiness scattered over this region is
interfering with detection. Any leftover smoke is due to the ongoing daily
large number of fires burning across the South Central and Southeastern
portions of the country.

Southwestern US:
Strong gusty southwesterly winds across the Southwestern US is likely
causing areas of blowing dust with reports of blowing dust noted in a
couple of observations from northern and central New Mexico. However,
cloudiness is widespread over a good portion of the Southwest which is
preventing detection in satellite imagery.

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. THE SMOKE TEXT PRODUCT IN
GENERAL SHOULD BE SENT TO SSDFireTeam@noaa.gov

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.
