DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0330Z April 13, 2017

SMOKE:
North Central US...
A large patch of leftover thin density smoke was seen over portions
of South Dakota, Minnesota, Nebraska, and Iowa. The smoke may extend
farther to the east and northeast, but significant cloudiness in that
area is hindering smoke detection from satellite imagery. This leftover
smoke is mainly from yesterday's tremendous amount of seasonal burning
occurring over the Flint Hills region of eastern Kansas. The batch of
smoke lifted to the north and northeast overnight and became entrained
into the circulation around a low pressure system. On the back edge of
the low pressure system, some clearing this evening allowed for viewing
of the smoke which now appears to be spreading back to the south in the
wake of the low pressure.

Kansas...
More fire activity in and around the Flint Hills region of eastern Kansas
resulted in more smoke which appeared to move northward during the day
though cloudiness in the area limited additional information on smoke
extent and density from satellite imagery.

Gulf of Mexico/Bay of Campeche...
An area of thin to moderately dense smoke attributed to the ongoing
seasonal burning occurring in portions of Mexico and Central America was
seen over the Bay of Campeche extending northward over the south central
and western Gulf of Mexico. Farther to the east, a swath of thin density
smoke drifted westward over the eastern to central Gulf of Mexico which
is believed to be from some of the recent fire activity over Florida,
the Bahamas, and Cuba.

DUST:
Arizona/Utah/Wyoming/Colorado/New Mexico...
A swath of thin density aerosol was noted stretching from Arizona and
western New Mexico northward to southwestern Wyoming. Aerosol models
are indicating this is likely composed at least in part by dust though
the source is not clear.

Nevada...
A few streaks of moderate to locally thick blowing dust were visible
moving to the northeast from a few sources in west central Nevada this
afternoon and early evening.

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.
