DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1745Z August 13, 2012

Western Two-thirds of the US:
An area of moderate-to-thick density smoke was present across northern
California/southeast Oregon/southern Montana/Idaho/Wyoming this
morning traveling to the east into the western portions of South
Dakota/Nebraska. This remnant smoke can be attributed to the large
wildfires in the northwest US that continue to emit copious amounts
of smoke. Lighter remnant smoke from these wildfires has made its way
through the central and southern plains and could be seen wrapping south
and westward around the surface ridge back into the four corners region.

Canada:
A large area of thin-density remnant smoke could be seen across the
Northwest Territories/Nunavut/Saskatchewan/Manitoba/Ontario/Quebec
this morning. In addition, an area of medium-density smoke was visible
in eastern Saskatchewan/Manitoba/southeast portion of the Northwest
Territories/southern Nunavut/Hudson Bay extending as far southward as
the Minnesota/Canadian border. These areas of smoke, which are likely a
mix of remnant smoke from Canadian and Siberian wildfires, were shifting
east-southeast into Quebec/Minnesota/Great Lakes Region.

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.
