DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0400Z August 07, 2012

Northwest US:
Active wildfires primarily located in Oregon, California, Nevada, and
Idaho are contributing to a massive are of light density smoke over
the Northern US. Throughout the day, remnant smoke pushed northward over
Oregon and Washington and eastward  across the central plains. The leading
edge of the smoke plume appears to be the eastern border of Minnesota
and Iowa. The heaviest smoke is located over eastern Oregon and Idaho.

Canada:
A large area of thin-density remnant smoke was analyzed over the Northwest
Territories this evening. Smoke producing fires in the region, as well
as remnant smoke transported from Asian fires, are likely contributing
to this area. Smoke is moving southeastward.

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:

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.
