DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0132Z July 31, 2021

Canada/U.S...
The expansive area of varying density smoke remained this late
afternoon. The smoke is attributed to significant wildfire activity
in central, south central, and southwestern Canada, along with the
northwestern and western CONUS. Smoke continues to be observed covering
an area extending from the Pacific Northwest into and across almost all
of Canada, where the fire activity in east-central Manitoba and western
Ontario adds to the area of smoke. Following a ridge, light smoke covers
the NW US, much of Canada and the high plains of the US before diving down
over the Midwestern US, Mississippi valley, Great Lakes and continues east
across the Ohio Valley, southeastern US, and mid-Atlantic region where
it exited into the western Atlantic. Light smoke extended northeast in
the Atlantic Ocean off of a majority of the east coast and moving all the
way towards the coast of Newfoundland. Medium density smoke covered most
of the western US and Canada as well as the high plains and mid-west. A
very large amount of dense smoke was also observed from British Columbia
and extended to the east over south central to eastern Canada and then
to the south and southeast over roughly the northern portion of the
country through the eastern part of the U.S.

Hawaii...
In northern Hawaii a moderate to heavy density smoke plume attributed
to wildfires was observed moving west.

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