DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0200Z October 2, 2011

Northern and Central US:
Visible imagery indicated patches of leftover thin to moderately dense
smoke extending from eastern Montana and western North Dakota southward
to western Kansas. The smoke in the southern part of this area was
believed to be due to a large fire which erupted yesterday in western
South Dakota. This fire was not detected in satellite imagery during
the day. The smoke in the northern portion of this area was likely from
ongoing fires to the west over parts of Wyoming, Montana, and Idaho.

Western and Northwestern US:
More fires were analyzed during the day across the area from central
California to north central Idaho, western Montana, and northwestern
Wyoming. Several significant smoke plumes were evident with the fires
over east central California, west central Nevada, and north central
Nevada. The fires in north central Nevada were particularly notable
and were believed to be ignited by lightning last evening. Thin smoke
was present from west central Nevada to southern Idaho with moderately
dense to locally dense smoke closer to the active fires. Cloudiness
over Washington, Oregon, Idaho, western Montana, and northern Wyoming
interfered with fire and smoke detection. Only a few smoke plumes were
visible in between breaks in the clouds in this region.

Middle to Lower Mississippi Valley:
Mainly agricultural fires were numerous again today over far southeastern
Missouri, eastern Arkansas, and northwestern Mississippi. A number of
smoke plumes emanated from these fires and moved off to the south during
the afternoon and early evening.

Northern Plains/South Central Canada:
Many seasonal fires were analyzed again across North Dakota, northwestern
Minnesota, southeastern Saskatchewan, and southern Manitoba. Some
smoke was analyzed, but cloudiness interfered with smoke detection in
satellite imagery.

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.
