DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1700Z April 25, 2023

SMOKE:
Central U.S...
Remnant thin density smoke from agricultural burning activity within the
Central U.S over past few days was observed extending east from South
Dakota and parts of northwestern Nebraska into most of Iowa.

SMOKE/AEROSOL:
Southern U.S/U.S Gulf States/Mid-Atlantic/Gulf of
Mexico/Caribbean/Mexico/Central America/Pacific...
The ongoing significant and widespread seasonal fire activity in Mexico
and Central America resulted in a very large area of light to moderate
density smoke which covered southern Texas while extending through
the U.S Gulf States and into the Atlantic Ocean off the coast of North
Carolina. This large area of smoke also covered much of southern and
eastern Mexico, northwestern Central America, the Pacific Ocean south
of the southern coast of Mexico and northwestern Central America, the
Gulf of Mexico, and the western Caribbean. Most of the moderate smoke
was seen over southern Mexico, parts of northwestern Central America, and
southern Gulf of Mexico. The thickest smoke was present over northwestern
Central America, portions of southeastern Mexico, and the Bay of Campeche.
Although most of what was seen in satellite imagery was believed to be
smoke, some aerosols from industrial activity primarily from Mexico and
Central America may be contributing.

Unknown Aerosol:
Mid-West/Manitoba/Ontario…
A thin patch of unknown aerosol was seen extending from northern
Manitoba, through parts of western Ontario, and into the Midwest. Within
the Mid-west region, the aerosol extended southeast through the Great
Lakes region and into the Ohio Valley region. This unknown aerosol is
likely high-lofted dust originating from large dust storms brought by
the Taklamakan and Gobi deserts.

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.
