THROUGH 2345Z APRIL 15, 2006.

Updated to add sand storm across AZ.

Central and Southern High Plains (NM/TX/OK/KS/NE):
A large fire along the De Baca/Guadalupe/Lincoln county line in New
Mexico has produced a narrow plume of moderately dense smoke that has been
rapidly moving E into the TX panhandle. The smoke extends more than 315km
from the source with an average width of 27km with the leading edge now
crossing the northwest extents of the Palo Duro Canyon.  This smoke is
mixing with a larger area of airbourne dust/sand that will be described
further below.
A fire near Lelia Lake in Donley county is producing thin to moderately
dense smoke that extends ENE 120km into Beckham county OK.  The plume
is about 15km wide.

A very intense cyclone located near Kearney, NE has been producing very
high surface winds across much of the central and southern Great Plains
which has lead to producing a moderately dense area of airborne dust.
The most dense dust/sand wraps in a band in the dry slot around the
cyclone...this extends in a band that expands from about 31km wide near
near Lexington, NE to 20km N of Broken Bow, to York wher it expands to
about 100km wide as it bands SW through Concordia, KS to Pratt, KS to
Gage, OK to Canadian, TX.  A band of sand/dust extends ahead of the dry
line from Burlington, KS SW to Ponca City, OK to Childress, TX...where
there are clearly more dense plumes that appear to be coming from source
regions near the Antelope Hills of W OK.  A third area of dust and sand
can be seen wrapping around the southern side of the cyclone and is
covering most of NE and N central KS from Goodland to Hill City to NW
Jewell county.

A large area of dust/sand is blowing across E AZ from the Phoenix metro
area in Maricopa and Pinal counties.  The plume is dense in a 70km
wide area that extends from the source region across S Gila, S Navajo,
S Apache, N Greenlee and N Graham counties with the leading edge entering
NM near in the N San Franciso Mtns. of N Catron county.

Virginia/North Carolina:
A large fire north of Patrick Springs in Patrick county is producing a
large amount of moderately dense smoke that is fanning out from due E
to SE of the origin.  The fan extends more than 185km to the east into
Lunenburg and Mecklenburg counties and extends southeast more than 225km
into central North Carolina (Johnston county)

A fire near Monarch in Jones county is producing a thin plume of smoke
that extends NE 110km to the AL/MS boarder in Lauderdale county. The
plume is on average 10km wide.

An explosively dense smoke from a fire on the front range of the Sierra
Madre Oriental NE of Palmillas has reached and overshot the tropopause and
is now spreading both southeastward and westward.  The westward moving
plume extends 30km and is about 30km wide as well. The southeast moving
smoke is a little less dense, and extends 70km and is about 35km wide.



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.
