DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0300Z September 2, 2015

SMOKE:
Western US:
Moderately dense to thick smoke spread to the north and northeast from
an ongoing large wildfire burning in east central California with the
thicker smoke reaching into western Nevada. Active wildfires and plumes of
moderately dense to thick smoke were also visible moving to the northeast
from fires burning in northeastern Oregon, central and northern Idaho,
and western Montana.

Much of the US and Southern Canada:
An enormous coverage of detached smoke of varying density attributed to
the Western US wildfires could be seen in satellite imagery extending
from California northeastward to Montana. The detached smoke then could
be detected across a good portion of the Central US and from the Great
Lakes Region and Ohio Valley to the Middle Atlantic Region and the
Northeast and off the East Coast over the Atlantic. The smoke also
covered portions of southern Canada all the way from eastern British
Columbia to the Canadian Maritimes.

BLOWING DUST:
A small streak of thin density blowing dust originated from a point
source in south central Oregon around 22Z and continued to move to the
east until just prior to sunset.

AIRBORNE GLACIAL FLOUR:
Alaska:
The plume of either light density smoke leftover from an earlier active
fire nearby or possibly airborne glacial flour which was visible moving
south off the coast of Kodiak Island into the Gulf of Alaska had become
much less discernible in satellite imagery by later in the day. Another
streak of what is believed to be glacial flour lofted into the atmosphere
was seen moving to the south over the Gulf of Alaska from a source region
in southeastern Alaska to the east of Anchorage.

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:

ANY QUESTIONS OR COMMENTS REGARDING THIS PRODUCT SHOULD BE SENT TO

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.
