DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1700Z July 28, 2021

Canada/U.S...
The expansive area of varying density smoke attributed to significant
wildfire activity in central, south central, and southwestern Canada,
along with the northwestern and western CONUS, continues to be observed
covering an area extending from the Pacific Northwest into western and
central Canada, where the fire activity  in east-central Manitoba and
western Ontario adds to the area of smoke. From there most of the smoke
moves southeastward across the Great Lakes and Mid-Atlantic and then
turns northeastward across Nova Scotia and Newfoundland before moving
on out across the northern Atlantic. Some smaller amounts of smoke
are moving south from the Great Lakes across the Great Plains and the
southeastern CONUS.

DUST:
Bahamas/Greater Antilles/Bermuda…
A thin layer of Saharan Dust was observed across Jamaica, Hispaniola,
eastern Cuba, Turks and Caicos, the southeastern Bahamas, the Sargasso
Sea, and northeastward to just east of Bermuda.

Eastern Tropical Atlantic…
A second area of Saharan Dust was seen extending eastward from the West
African coast to about 50W. This was moving off toward the west toward
the northern Caribbean Islands.

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.
