DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0255Z August 11, 2012

Alaska/Beaufort Sea/Northern Yukon and Northwest Territories:
A stretched out area of light remnant smoke can be seen over northern
Alaska and far northwestern Canada. This smoke is believed to be high
level smoke from Siberia that has tracked eastward across the northern
Pacific Ocean.

Canada:
Thin to moderately dense smoke plume continues to cover most of western
and central Canada this evening.  Plume extends from Vancouver Island then
northeast over British Columbia and across eastern Northwester Territories
as it rounds the top of the ridge of high pressure. Smoke then drifts
southeastward across Central Canada and Central U.S.  Thin smoke is
seen further east over much of Hudson Bay, Ontario and western Quebec.
Smoke is likely comprised of both large fires burning across northern
Alberta and central Saskatchewan along with additional remnant smoke
from Siberian wildfires.

Northern and Central Plains:
Large area of thin density remnant smoke is seen across most of the
Central and northern Plain and even extends as far south as the Texas
coast.  Moderate dense smoke embedded in this smoke plume extends from
southern Saskatchewan/southern Manitoba provinces of Canada southward
to northeaster portions of Texas.  Smoke is likely due to three separate
source points; first being from Siberian wildfires, second from wildfires
in Alberta/Saskatchewan and third from wildfires burning across the
northwestern U.S.

Northwestern U.S.:
Several large wildfires are seen producing more heavy dense smoke over
California, Nevada, Oregon, Idaho this evening.  This is only adding
to the previous days remnant smoke that still remains across area.
Another plume of smoke is drifting south and east from the eastern
Pacific Ocean over western Washington/Oregon, which originated from
wildfires burning across Siberia.

THIS TEXT PRODUCT IS PRIMARILY INTENDED TO DESCRIBE SIGNIFICANT
AREAS 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.
