DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1700Z April 29, 2023

SMOKE/AEROSOL:
Texas/Louisiana/Gulf of Mexico/Western Caribbean/Northwestern Central
America/Mexico/Pacific...
Significant and widespread seasonal fire activity in Mexico and Central
America with aerosols from industrial activities originating in Mexico
and northwestern Central America resulted in a very large area of
primarily light to moderate density smoke which covered much of
southern/central Mexico, the western Caribbean, northwestern Central
America, the Pacific off the coast of southern Mexico and northwestern
Central America, the Gulf of Mexico, and southern Texas and Louisiana.
Moderate density areas of smoke were seen over southern/eastern Mexico,
the Yucatan Peninsula, northwestern Central America, and the western
Gulf of Mexico.  Heavy density smoke was found over northwestern
Central America, parts of southeastern Mexico, the Bay of Campeche,
and the Yucatan.

UNKNOWN AEROSOL:
South Central U.S...
A patch of unknown aerosol was observed briefly extending over Oklahoma
and parts of northern Texas. The aerosol may likely be a combination
of remnant sulfur dioxide from the eruption of Shelveluch volcano and
lofted dust originating from central/eastern Asia. This unknown aerosol
may extend further east into the Midwest and Eastern CONUS regions but
cloud cloud made it difficult for detailed analysis.


Montana/Alberta...
Brief remnant to light density smoke from small wildfires and seasonal
burning within western Canada and the U.S was seen over the border
between southern Alberta and northwestern Montana.

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.
