DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1500Z August 25, 2021

SMOKE:
Most of the United States and Canada...
Fires ongoing over the western United States and southern British
Columbia were producing a large area of smoke that was covering most
of the United States, except for portions of the Southern Plains and
Southwestern States, and also over much of Canada.  The highest density
smoke was extending from southern Ontario, through the Northern Plains,
northern Rockies and into Pacific Northwest and northern California.
Further to the north, mostly light density smoke was observed over central
and northern Canada from fire activity over western and northwest Canada.


DUST:
Atlantic/Caribbean…
A large area of Saharan Dust was seen over much of the Tropical Atlantic
Ocean and extending west through the Caribbean Sean and southeastern
Gulf of Mexico and then extending northeast through Florida and then
offshore the East Coast of the United States.

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.
