DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0300Z August 13, 2012

Northwestern US/Central Plains:
A fairly broad area of medium-to-thick density smoke was visible across
the northwestern US this morning stretching from northern California
eastward through Wyoming. As the day progressed, this area moved
southeastward into western Nebraska, northern Colorado, and northwest
Kansas. A larger area of light smoke was also present, extending from
the Oregon coastline into the Dakotas and southward towards Oklahoma. An
additional small area of thin-density smoke stretched across southern
Texas/Arkansas/Louisiana moving westward. These large areas of remnant
smoke likely originated from the numerous wildfires burning in northern
California/Idaho/Nevada that continued to emit large amounts of smoke
this afternoon.

Canada:
A large area of thin-density remnant smoke could be seen across the
Northwest Territories/Alberta/Saskatchewan/Manitoba/Ontario/northern
Quebec intermixing with clouds in the region this morning. An area
of medium-density smoke was also visible wrapping around the large
surface low and was located in the southern portion of the Northwest
Territories/Alberta/Saskatchewan/Ontario. These areas of smoke, which
are likely a mix of remnant smoke from Canadian and Siberian wildfires,
were dropping southeastward into the Great Lakes Region of the US. This
evening, the leading edge the the medium-density smoke was visible pushing
across the US/Canadian border into northern Minnesota and North Dakota.

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.
