SMOKE:
Northwestern CONUS....
An area of varying density smoke was observed blanketing northern
California, Oregon, Washington, southern British Columbia, Idaho,
western Montana, western Wyoming, northwestern Colorado, northern Utah,
and much of Nevada. The parent wildfire activity was located throughout
northern California, Oregon, Washington, southern British Columbia,
Idaho, and western Montana. Much of this smoke was moving off toward
the east-northeast, with a small portion making its' way west out into
the Pacific Ocean and south along the California coast.

East-central British Columbia...
Wildfire activity across east-central British Columbia was observed
producing heavy smoke. Cloud cover obscured the area for much of the
day. However, the thick smoke was observed after the cloud cover moved
off to the east. This thick smoke was moving off to the east slowly.

Much of northern and central Canada...
A large layer of light to moderate density remnant smoke was observed
covering much of northern and central Canada from the Northwest
Territories to western Quebec. theis smoke was becoming incorporated
into a few upper level systems...one over north-central Canada and
the other over Hudson Bay. The likely source for this smoke is China,
as visible imagery from Himawari suggests smoke extending northeastward
from Shanghai across Japan and then north into the Sea of Okhotsk.

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.
