DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0001Z July 31, 2021

Canada/U.S...
The expansive area of moderately dense to very dense smoke remained this
late afternoon and evening.

The smoke is attributed to significant wildfire activity in central, south
central, and southwestern Canada, along with the northwestern and western
US. Smoke continues to be observed covering an area extending from the
Pacific Northwest into and across northern/central Canada, parts of the
northern US and from the Mid-Atlantic into the southeastern US/Mississippi
Valley and eastern sections of central/southern Plains. Areas of thick
density smoke stretched across parts of central Yukon Territory and
into central sections of British Columbia, central/southern Alberta,
southern Saskatchewan, southern/central Manitoba and into the northern US
from Montana into northern Minnesota. Light smoke was seen from Alaska
across most of western/central Canada with cloud obscuring the view in
eastern Canada, south through the Pacific Northwest, across the Northern
US Rockies section into all of the Northern Plains and across parts of
the central/southern Plains. Then eastward into the Mississippi Valley,
southeast US and north into the Mid-Atlantic and southern sections of
the northeast and finally along the southeast coast out into the Atlantic.

DUST:
Lesser Antilles/South America…
A band of thin Saharan Dust was seen extending over the Lesser Antilles
and northern countries of South America and reaching near Central America.

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.
