DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0200Z August 16, 2012

Currently:
US West/Central Rockies/Central Plains:
Complex fires in N California, Oregon, Idaho, W Montana and Wyoming
continue to produce large areas of moderately dense to dense smoke.
The dense smoke from earlier in the day and previous day is now reaching
parts of the Central Plains including the states of Nebraska, Kansas
and Oklahoma.  Thinner smoke is reaching as far east as the Mississippi
Valley extending from S Minnesota and Wisconsin to N Texas and Louisiana.

Northern British Columbia:
Several wildfires have broken out across the northern section of the
region producing moderately dense to dense smoke moving east.

Earlier Today:

US West/Central Rockies:
Numerous large complexes of fires across N CA, OR, N NV, ID, W MT and
WY are producing a large amount of moderate to very dense smoke across
much of the West (including N CA, S 1/3rd of OR, N 1/3rd of NV, S ID,
all of WY, all of CO, all of NE and all but far SE KS).  The valleys of
CA and ID area particularly dense at the surface.  Much of the smoke
above 10,000ft is moving progressively east with a slight southward
change trajectory over the Plain states.

Nova Scotia:
Thin smoke can be seen moving east off over E Nova Scotia into the
Atlantic south of Newfoundland.

Labrador Strait:
Thin smoke can be seen swirling around a highly amplified ridge
across/anticyclone across the Labrador Sea, covering coastal regions of
Greenland, Baffin Island and Labrador.  This smoke is likely from output
from Canadian fires more than a week ago.

Western Canada:
A large trof centered over Hudson Bay is pulling thin to moderate smoke
down across the Yukon/NW Territories into Alberta, Saskatchewan, Manitoba,
W Ontario, over the Great Lakes and Michigan.  The smoke comes from
ongoing Canadian fire output over the last few weeks (as it appears to
be coming back from over the poles as well) as well as some contribution
from them over the last few days as well.

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.
