DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0200Z March 23, 2011

Southeast Coast:
The large area of light to moderate smoke mixed with other aerosols
discussed in the text product earlier this morning can still be seen
moving off the Southeast US coast. The source of this leftover smoke is
from numerous fires over the past several days which have been occurring
over the Southeastern US.

South Central and Southeastern US:
Once again during the day, many fires producing visible smoke in satellite
imagery were detected over the South Central and Southeastern US. The most
concentrated fires and smoke plumes were analyzed over eastern Alabama,
much of Georgia, southern South Carolina, and northern Florida. By
the end of the day, a number of the smoke plumes in this region had
merged to form larger patches of smoke. Farther to the west, cloudiness
significantly interfered with both fire and smoke detection in satellite
imagery across a rather large area extending from eastern Oklahoma and
eastern Texas to Tennessee and Alabama.

New Mexico/Texas/Kansas/Oklahoma:
Gusty winds were responsible for fanning several rapidly spreading
fires particularly over western Oklahoma, southwestern Kansas, and
southwestern Texas. Locally dense smoke closer to the fires particularly
in western Oklahoma and southwestern Kansas spread rapidly to the east and
northeast during the afternoon and fanned out to cover a large portion
of northwestern Oklahoma and much of Kansas. In addition, blowing dust
continued to be seen in satellite imagery. By late afternoon, a swath
of thin to moderately dense blowing dust extended from western Texas
near Midland northeastward across central Oklahoma to southeastern
Kansas. Rather thin density blowing dust also was observed moving to
the northeast from the White Sands region of south central New Mexico.

Southern Texas/Northern Mexico:
Several large fires just south of the border in northern Mexico were
emitting dense smoke plumes which moved to the northeast and across the
border into southwestern Texas near Del Rio.

Western Gulf of Mexico:
A band of aerosol was observed just off the coast of Texas extending
southward to the Bay of Campeche. This aerosol may contain some smoke
from the seasonal fires which have begin in Mexico and Central America. It
also may be attributed to the oil wells in the Bay of Campeche.

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.
