DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1645Z April 25, 2012

Gulf of Mexico:
Thin remnant smoke from a fire in coastal MS last evening moved south
across the Central Gulf overnight... since then the smoke plume as
bifurcated based on difference in height.  Low level smoke extends
from the mouth of the Mississippi River NE across to Pensacola, FL.
Mid level smoke extends south then southwest from about 20 km SE of the
Mississippi Delta to just past 90W about 230km south of LA.

Deep South:
A narrow band of very thin smoke could only be seen very early in the
morning at steep sun angle across central GA, South Central AL into the
coastal counties of MS.  This area was likely from other fires burning
across TX, LA and MS last night.

New England:
An area of unknown aerosol (possibly sulfates based on forecast models)
can be seen off shore of New England and covering Cape Cod, Nantucket and
Martha's Vineyard. This area is moving due east behind an old cold front
or sfc boundary and extends to the south along 70W as far south as 38N.

Great Lakes:
An very narrow (20km wide) band of very thin unknown aerosol (possible
Asian dust) is at a very high altitude that extends from Hudson Bay
across E Ontario, across Lake Erie into N and C PA and Western NY.
The SW portion is moving rapidly ESE but is becoming difficult to see
at higher sun angles.

New Mexico/W Texas:
What looks like remnant smoke from fires in southern NM, the West Texas
Panhandle and possible fires in N Chihuahua in Mexico can be seen in
early Goes-West imagery slowly drifting Eastward across the Plains of
SE NM into the southern CapRock and western TX panhandle toward the Big
Bend Region.  It is possible though unlikely there is mixed dust and
sand within this area of aerosols.

THIS TEXT PRODUCT IS PRIMARILY INTENDED TO DESCRIBE SIGNIFICANT
AREAS SMOKE ASSOCIATED WITH ACTIVE FIRES AND SMOKE WHICH HAS BECOME
DETACHED FROM THE FIRES AND DRIFTED SOME DISTANCE AWAY FROM THE SOURCE
FIRE..TYPICALLY OVER THE COURSE OF ONE OR MORE DAYS. AREAS OF BLOWING DUST
ARE ALSO DESCRIBED. USERS ARE ENCOURAGED TO VIEW A GRAPHIC DEPICTION OF
THESE AND OTHER PLUMES WHICH ARE LESS EXTENSIVE AND STILL ATTACHED TO
THE SOURCE FIRE IN VARIOUS GRAPHIC FORMATS ON OUR WEB SITE:

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.
