SMOKE:
Southern Half of Canada/Much of the US...
Significant wildfire activity scattered across the Western US from
northern California and northern Nevada northward across portions of
Idaho, western Montana, and the Pacific Northwest as well as a massive
wildfire outbreak occurring  in western Canada and primarily in British
Columbia continued to be responsible for widespread coverage of smoke
of varying density affecting most of the southern half of Canada as well
as much of the U.S. Only the Southwestern U.S., southern Texas, and the
far eastern U.S. as well as southeastern Canada were relatively smoke
free at least as far as what was seen in visible satellite imagery. The
most significant smoke of moderate to thick density affecting the US
blanketed the northwestern portion of the US from western Montana,
and western Wyoming westward to the portion of the West Coast from
northern California to northwestern Washington. The smoke also extended
offshore of California, Oregon, and Washington over a portion of the
nearby eastern Pacific. Relatively narrow swaths of heavy density smoke
extended eastward from Montana and Wyoming to the North and Central Plains
and western Great Lakes Region and from the Southern Plains extending
east into the southeast of the U.S. Over Canada, thicker smoke covered
much of British Columbia, portions of northern and central Alberta,
northern and central Saskatchewan, and northern and central Manitoba.

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.
