DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0300Z September 8, 2018.

NESDIS IS INVESTIGATING THE UTILITY OF THIS TEXT NARRATIVE.  IF YOU FIND

SMOKE:
Western U.S. to North Central U.S./Southwestern to South Central Canada...
Wildfires burning over portions of northern California, Oregon, Idaho,
western Montana, and Washington were responsible for a large mass of
varying density smoke which extended from northern California and the
Pacific Northwest eastward to the North Central U.S. Moderate density
smoke emanating from the Western U.S. fires reached as far east as the
Dakotas while the thickest smoke was visible over northern California,
central and southern Oregon, and far northwestern Nevada. Another area of
thicker smoke was present over far northern Washington, northern Idaho,
and the northern half of Montana as well as southeastern British Columbia,
southern Alberta, and southern Manitoba in Canada.

Canada...
The large area of light density remnant smoke observed this morning
blanketing much of northwestern and southern Canada from the Northwest
Territories extending to western Quebec was still somewhat visible in
the same general region later in the day. This smoke could be left over
long range transport of smoke from wildfire activity in Asia though some
of it also may be from wildfires in western Canada and the Northwestern
U.S. Closer to the more significant wildfires burning in western British
Columbia, widespread cloud cover moved across the region during the day
greatly limiting smoke detection in satellite imagery.

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.
