DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1700Z July 31, 2017

SMOKE:
Southern Canada into Hudson Bay...
A fairly large region of mixed density smoke is analyzed over southern
Canada into the Hudson Bay region. This region of smoke has its origins
in southern British Columbia, where a large complex of fires continues to
burn. The easternmost portion of the smoke plume is of light density. This
smoke has been ingested within a cyclone currently over far eastern
Manitoba. Over southern Saskatchewan, southern Alberta, and west-central
Manitoba, the smoke plume is of moderate density. Nearest the source
region in southern British Columbia and portions of southern Alberta,
the smoke is quite dense.

Northwestern US...
Active fires throughout the northwestern United States are producing light
to moderate smoke plumes. Much of the plume is tenuous in nature, but over
northern California, south central Oregon, and much of Montana, moderately
thick smoke plumes are seen emanating from specific fires. Elsewhere
throughout the northwestern United States, the smoke is more remnant,
such as over eastern Washington state and the northern part of the
Nevada-Utah border.

Alaska/Northern Yukon...
Fires over northeastern Alaska are producing a light smoke plume
throughout northeastern Alaska and the northern portions of the Yukon
Territory.

Northwest Territories...
Fires throughout the Northwest Territories are spawning a mixed density
smoke layer over the central Northwest Territories. Much of the layer is
light density, but a seemingly remnant layer of moderate density smoke
can be observed within the region of lighter smoke.

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.
