DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0123Z August 7, 2021

SMOKE:
Canada/U.S...
The huge expanse of varying density smoke attributed to significant
wildfire activity in central, south central, and southwestern Canada
along with the northwestern and western U.S. was again visible covering
nearly all of Canada and most of the U.S. with the exception of the
Southeast and a portion of the southwest. Thicker smoke from fires in
east central and northeastern California and south central Oregon spread
to the northeast and merged with thick smoke produced by wildfires in
central and eastern Washington, northern Idaho, western Montana, and
southern British Columbia. From there the thicker smoke extended to the
east over central Canada and the northern and central/eastern U.S. and
then to the south and southeast over roughly the northern and central
portion of the country. Smoke also extended well off the U.S. east coast
across a significant portion of the Atlantic south of Greenland and off
the coast of Oregon/California over portions of the Pacific.

Alaska/Northwestern Canada...
Wildfires scattered across eastern Alaska, the Yukon, and portions of
the Northwest Territories in northwestern Canada were responsible for a
broad area of light to moderate density smoke which covers cental Alaska
and much of northwestern and north central Canada with the eastern and
southern portions of the smoke likely mixing with smoke from the fires
farther south and east in Canada.

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.
