SMOKE:
Western Canada, Western U.S., and Northern U.S....
Continued wildfire activity predominately in British Columbia and
Washington State, with additional activity throughout the remainder
of the western U.S., continues to produce areas of thick smoke. From
Washington and west-central British Columbia, the thickest smoke is
drifting south and west over the Pacific Ocean, where it diffuses
into light and medium-density smoke and turns back eastward and inland
over northern California and Oregon.  Here, further fire activity adds
locally thick smoke to the plume, which continues east-northeastward
across Nevada, Idaho, and Wyoming.  In addition, fire activity from
central and northern British Columbia is producing thick smoke, which
is moving generally eastward. Light remnant smoke originating from this
region is seen over the Canadian provinces east to western Ontario and
over the northern U.S. from Montana to Minnesota.

Southern U.S....
An area of medium-density smoke is seen from Kansas to Louisiana drifting
southward.  Wisps of light smoke are seen from Arizona to Missouri,
with the highest concentration seen in a clockwise circulation centered
on the Arizona/New Mexico border.

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

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.
