DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0300Z April 25, 2011

Blowing Dust:
A large area of blowing dust originates from Roosevelt County, NM as
well as Terry and Hockley counties in TX.  The 20kt winds in the area
are moving the dust eastward.

A discrete area of dust can be seen moving east from an area west of
Dilkon, AZ.

Originating from the Mojave National Preserve, an area of dust is moving
to the east.

Two large areas of blowing dust are in Arizona.  One originates from
central Esmerelda County and the other from northeastern Mineral County.
The dust is moving to the east and has reached the Utah border.

Smoke:
Gulf of Mexico:
Remnant smoke from fires in Mexico and throughout Central America is
covering the western and central portion of the Gulf of Mexico and
moving north into Texas, Louisiana and Mississippi where it is obscured
by clouds.

Texas:
Large fires in the western portion of the states are creating moderately
dense areas of smoke which are extending to the east.  In the panhandle
of Texas, smoke is mixing with blowing dust.


Earlier:
Northern Plains/Midwest/Southwest Canada:
A thin and large area of aerosol of unknown origin and composition was
seen stretching from northeast British Columbia southeastward across
Canada into the northern Plains of the United States and across part
of the Midwest just southwest of Lake Superior. In the US, this aerosol
covered portions of Montana, the Dakotas, Minnesota, Wisconsin, and the
U.P. of Michigan. This aerosol could be remnant dust from eastern Asia
that had been moving across the Aleutians over a week ago, but it cannot
be certain.

Texas/Northeast Mexico:
An area of thin to moderate density smoke was present over northeast
Mexico, central/northeast Texas, and extreme south central Oklahoma
this morning. Clouds likely obscured the full extent of the smoke in
Texas. This remnant smoke is likely from the fires that were burning in
northern Mexico, west Texas, and southern New Mexico yesterday.

Gulf of Mexico/South Florida:
Remnant smoke from Mexico could be seen drifting northward across the
western Gulf today towards the Texas and Louisiana coasts. In addition
thin smoke was emanating from western Cuba to the northwest. A very
small patch of thin smoke was seen crossing the waters just southeast
of the Florida Keys and likely came from one of the fires in the Bahamas
yesterday given the easterly flow over this region today.

Mid-Atlantic Coast:
A thin unknown aerosol was seen rotating northeastward along a frontal
boundary today off the Virginia/Maryland/Delaware/New Jersey coasts. It is
not believed to be remnant smoke but its actual composition is not known.

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.
