DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0200Z September 21, 2012

Pacific Northwest
Several large wildfires in Oregon, Washington, Idaho, and Montana are
producing a vast area of remnant light density smoke that stretches
from southern British Columbia southeast over the Pacific Northwest
and into the central plains reaching as far east as Kentucky and as far
south as central Texas. Moderate to very dense smoke is observed this
evening over the named states in which wildfires are active plus areas
of western Wyoming and northern Utah.

Canada
From Earlier:
A small patch of light remnant smoke could be seen over Alberta this
morning. This smoke is likely due to the fires located in northern
British Columbia and Alberta and is dropping southward.
This Evening:
Patches of locally dense smoke are present in the immediate vicinity of
fires in central and northern British Columbia and northern Alberta.

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.
