DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0145Z April 23, 2013

Smoke:
Lower Mississippi Valley:
Numerous fires over eastern Texas, eastern Oklahoma, Louisiana and
Arkansas produced large smoke plumes this afternoon and evening with
the smoke drifting to the north.

Southern Gulf of Mexico/Central America:
A large area of thin to moderately dense smoke is seen covering much
of central portions of Central America including the Yucatan, southern
Mexico, Guatemala and Honduras and extending into the southwest Gulf of
Mexico and the East Pacific. This smoke is from the extensive seasonal
burning throughout the region.

Dust/Aerosols:
Southern Plains:
A sharp cold front with very strong winds was dropping south over the
southern Plains into the Texas and Oklahoma panhandles. It was kicking up
an area of light to moderately dense blowing dust that was surging south
with the front. An area of light blowing dust was noted ahead of the front
coming off of White Sands in southern New Mexico and in adjoining areas
of eastern New Mexico and west Texas. This dust was moving to the east.

Great Basin and Four Corners:
Several areas of blowing dust were detected across the region. One was an
area of light to moderately dense dust over northeast Arizona moving to
the east into New Mexico. Two source areas of moderately dense blowing
dust were seen over Nevada – one was over northern Churchill county
and the other over northeast Nye county. The dust was moving to the south.

Long range dust:
Elevated dust (higher altitude) due to long range transport from Asia was
seen curling south and southeastward along the West coast from coastal
Oregon and Washington into northern Nevada.

THIS TEXT PRODUCT IS PRIMARILY INTENDED TO DESCRIBE SIGNIFICANT AREAS
OF 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.
