THROUGH 2300Z November 27, 2005

N Texas:
A large fire near Harrold,TX in Wilbarger county is producing moderately
dense smoke that extends E into the larger dust and sand storm that is
affecting the region described below.

A moderately dense sand and dust plume behind the cold front is being
transported E on 30mph winds with higher gusts from the source region of
the Southern Cap Rock and Escarpment with the most dense sand/dust out
of Gaines/Dawson/Martin/Andrews counties.  The sand extends E covering
the 2 rows of counties to about Jones county where winds shift to SWly
and extend NE into Oklahoma as far as Payne county.  The dust and sand
of course becomes less dense the further from the source.

Chihuahua/West TX Panhandle/C Texas:
An extremely dense sand/dust plume from the dry lake beds of N Chihuahua
state in Mexico had been moving due E extending into the Western Panhandle
of TX maintaining its high density to Sutton and Schleicher county
where it continues to move E along on ahead of the cold front as far as
Mills county TX and becomes fainter the further east it goes.  However,
with the cold surge now more focused toward the SE (NWly flow aloft)
the highest density dust/sand is now moving SEward and is currently
covers most of NE Chihuahua and extreme northern Coahuila in Mexico,
Presidio, Pecos, Terrell and Brewster counties in TX.

New Mexico:
With strong NW winds sand from White Sands region of NM is becoming more
dense (moderate to dense) and currently extends SSE to the NM/TX boarder.

Moderately dense dust/sand extends SW along the Gulf of California coast
line from deserts SE of Isla Tiburon. A slight shift in winds from NNW
to NW has increased the density of sand and dust which currently extends
to Guaymas in Sonora State.
Just SE of the first plume, a second source region in the sands W of
Ciudad Obregon is producing similar conditions further down the coast
to Los Mochis in NW Sinaloa State.

Baja California Sur:
Large areas of sand and dust are blowing over 175km offshore SW of the
source regions near Laguna San Ignacio.  A smaller narrower plume extends
71km SW from its source near Bahia Tortugas along the Western coast SW
of the Sierra Vizcaino.



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.
