DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0000Z May 25, 2025

SMOKE:
Northern Plains/Central and Northeastern Canada…
Wildfires across far southeastern Manitoba and extreme southwestern
Ontario were producing thick smoke that was seen moving southeast by the
time sunset arrived. Smoke from earlier in the day could be seen as far
south as the South Dakota-Nebraska border and extending off toward the
west-northwest into south-central Canada. The smoke could, from there,
be seen moving northward, where the smoke was moving over a larger
area of wildfire activity across central Saskatchewan into northwestern
Manitoba. This activity is adding thick smoke to the plume as it continues
curving toward the Nunavut-NW Territory-Saskatchewan-Manitoba quadruple
point then east-northeast over northern Manitoba, southern and eastern
Nunavut, northern Hudson Bay, far northern Quebec, and over the Davis
Strait.

AEROSOL/SMOKE:
Mexico/Central America/Western Caribbean/Tropical Eastern Pacific/Gulf
of America/Gulf Coast/Southern Plains/North Atlantic…
An area of light to moderate density smoke and aerosols - attributed
to widespread seasonal fire activity throughout much of Mexico, Cuba,
Hispaniola, and parts of the southeastern CONUS coupled with gas
flaring in the Bay of Campeche and surrounding areas in the Mexican
coastal plain and industrial sources throughout portions of Mexico was
observed blanketing an area extending from Cuba and Hispaniola westward
the Yucatan and Bay of Campeche, where moderate smoke was added to
the layer as it moved northward into the southern Plains. From there,
some smoke was drawn eastward along with from both active and remnant
smoke from agricultural burning across the southeastern CONUS out over
the northern Atlantic almost as far as Cape Race. Some of the emissions
from the Pacific side of Mexico were also helping to create a light smoke
layer across the tropical Eastern Pacific. Some contributions might be
made from the gas flaring and burning along the Mexican coastal plain
around the Bay of Campeche as well through the Isthmus of Tehuantepec.

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.
