DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1700Z April 19, 2021

SMOKE:
Central Mississippi Valley, Northern Ohio River Valley, and Southeastern
U.S…
A large region of remnant light density smoke likely attributed to
yesterday’s seasonal fire activity over the Central U.S. was observed
over a large portion of the Northern Ohio River Valley as well as over
parts of the Central Mississippi Valley. Light density smoke was also
observed over parts of the Southeastern U.S. in this morning’s GOES
visible satellite imagery.

Mexico, Gulf of Mexico, Guatemala, South Florida, Western Caribbean Sea,
and Atlantic Ocean...
A broad region of light to moderate density smoke likely attributed to
widespread seasonal fire activity over Mexico was observed over most of
Guatemala, Southeastern/Eastern Mexico including the Yucatan Peninsula,
and over the Bay of Campeche. Smoke was also observed over parts of
the Western Caribbean Sea and over the Central and Southeastern Gulf
of Mexico. Light density smoke was also observed over South Florida,
however cloud cover over this region made the smoke analysis difficult
this morning. Light density smoke was observed as well over the Northern
Bahamas and a large region of the Western Atlantic Ocean just to the south
of Bermuda. Light density smoke was also observed offshore from Southern
Mexico over parts of the Eastern Pacific Ocean in this morning’s GOES
visible satellite imagery.

DUST:
Eastern/Central Tropical Atlantic, Western Atlantic, and Caribbean Sea...
A large region of light to moderate density Saharan dust was observed over
parts of the Eastern and Central Tropical Atlantic Ocean. Light density
Saharan dust was also observed over parts of the Western Atlantic Ocean
including parts of the Bahamas and as well over parts of the Caribbean
Sea in this morning’s GOES visible satellite imagery.

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.
