DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1545Z August 26, 2013

From the Western US wildfires:
Expansive area of smoke originating from large wildfires in California
and Idaho stretch from portions of the northern Rockies , into central
Canada and across much of the central US.  Moderately dense smoke is
seen billowing from the Rim wildfire this morning with moderately dense
smoke protruding northeastward across northern Nevada, eastern Oregon,
central Idaho and western Montana.  The area of smoke that has moved
south and east across the central US remains trapped under a dome of
high pressure and is mixing with haze/pollution.  The smoke over this
region is generally light and is observed nicely in GOES-WEST due to
the optimized sun angle in the morning.  At this time the full extent
of the smoke over the eastern half of the US cannot be identified since
GOES-WEST does not extend far enough east and smoke is not showing up
in morning GOES-EAST imagery.

Newfoundland/Nova Scotia:
A narrow ribbon of light density smoke is seen moving eastward over
the northern Atlantic Ocean just off the coasts of Nova Scotia and
Newfoundland.  Smoke likely originated from the western US wildfires.

THIS TEXT PRODUCT IS PRIMARILY INTENDED TO DESCRIBE SIGNIFICANT AREAS
OF 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.
