DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1700Z April 16, 2011

Southeast US/Central and Eastern Gulf of Mexico:
A plume of thin smoke was moving eastward across the northern Gulf of
Mexico and southeaster U.S. this morning in conjunction with movement of
a frontal boundary. On the far southwest end of this plume and across the
western Gulf of Mexico, smoke became moderately dense. Much of this smoke
was entrained by this frontal boundary as it moved across the Central
Plains over the past day or so and because of that, most of the smoke is
believed to have come from the wildfires in west and west central Texas,
southwest Oklahoma, and northern Mexico. Another area of older remnant
smoke can be seen a little further off the southeast US coast and is
probably the same area of smoke that came from the numerous fires in
the Southeast on Thursday.

Northeast Mexico/Texas/Western Gulf of Mexico:
This morning, thin to moderate density smoke was still lingering over
west central Texas and the Texas panhandle from the large wildfires still
burning over portions of Texas and northern Mexico. In this part of the
state, remnant smoke was drifting northwestward across the panhandle and
into eastern New Mexico/southwest Oklahoma. Clockwise flow from surface
high pressure over the center of Texas also has remnant smoke in the
eastern parts of the state rotating southward across the western Gulf
and then southwest into deep southern Texas/northeast Mexico, where it
eventually starts to wrap back around to the north. There was a small
patch of remaining dense smoke still that was moving across southern
Texas towards the Gulf of Mexico.

Central Plains:
Airborne dust particles from yesterday's large blowing dust event from
Colorado/Kansas to Texas/Oklahoma could still be seen this morning
across southeast Nebraska/eastern Kansas/eastern Oklahoma/northeast
Texas/Arkansas/north Louisiana/and Mississippi. This elevated dust plume
may stretch even further but it could not be seen from the GOES-W imagery.

Southern California/Baja California:
A large area of aerosol believed to dust that traveled from east Asia
could still be seen off the southern California coast and west of Baja
California. It was generally drifting southward.

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.
