DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0200Z April 14, 2018

SMOKE:
Central US...
Major wildfires were burning in western Oklahoma and northwestern Texas
resulting in a large mass of moderate to thick density smoke which spread
very quickly to the east and northeast covering much of northwest and
north central Texas and the western two-thirds of Oklahoma. The smoke then
spread northward around the southern and eastern portion of a low pressure
system and enveloped central and eastern Kansas and up into southeastern
Nebraska and southwestern Iowa. Smoke likely extended even farther to
the north but cloud cover limited detection from satellite imagery.

Southwestern Texas...
A couple of large fires in the Mexican state of Chihuahua produced thick
smoke which rapidly spread to the east and fanned out with the leading
edge of thinner density smoke moving into southwestern Texas to the west
of the Big Bend region.

Western Gulf of Mexico/Southern and Southeastern Texas/Southern
Louisiana...
A large area of thin density smoke from the very significant amount of
seasonal burning occurring over Mexico and Central America was visible
moving to the north over the Bay of Campeche and the western Gulf of
Mexico with very thin density smoke likely reaching into southern and
southeastern Texas and southern Louisiana though cloud cover is limiting
detection from satellite imagery.

Southeastern US and Middle-Atlantic Region...
Quite a few fires and smoke plumes were analyzed across the Southeastern
US and the Middle-Atlantic Region with the majority of the smoke moving
to the north or northeast. Most of the smoke plumes were of thin density
though a few thicker ones were noted as well.

DUST:
Southwestern and South Central US/Northwestern and North Central Mexico...
A major blowing dust event was occurring over portions of the Southwest
and South Central US and northwest and north central Mexico. A large
swath of moderately dense to locally thick dust from a number of
sources was visible across southern New Mexico and the region from
southwestern and western Texas to north central Texas where it mixed
with smoke from wildfire activity. Moderately dense to thick dust could
also be seen moving to the east and southeast over northern Chihuahua
in north central Mexico. Thinner density blowing dust mixed with the
wildfire smoke spread to the northeast and north across Oklahoma as
well. Farther to the west and southwest, thinner density blowing dust
was visible moving to the southeast from a few spots in southeastern,
south central, and southwestern Arizona as well as far northwestern
Mexico bordering the Gulf of California.

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.
