DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1715Z August 21, 2013

Northern US/Central and Southern Plains/Northern Mexico/Southeast Canada:
The large number of wildfires in the western US continue to generate a
large quantity of smoke that is spreading across the northern tier of
states across the country and into the Atlantic with an area also peeling
off to the south through the Plains into northern Mexico. The smoke
mainly extends from the fires in Idaho, western Montana and northwest
Wyoming eastward across the Dakotas, the northern Mississippi Valley,
the Great Lakes States, New England and the northern mid Atlantic,
southeast Ontario and southern Quebec and finally exiting off the coast
of New England and New Jersey. A large patch of smoke also drops south
across the Central and Southern Plains and then curves to the west across
the Texas Panhandle and southern New Mexico into northern Mexico. There
were significant areas of moderate to dense smoke that were observed
across Michigan and into Indiana with another area from Wisconsin and
Iowa across western Missouri and eastern Kansas across central Oklahoma
and the southern Texas Panhandle. More areas of moderate to dense smoke
were seen near the fire source regions.

California/Oregon/Washington:
Several large fires were burning this afternoon and evening in the central
and northern Sierras and the Klamath range in northern California. The
Rim fire the central Sierras in particular was generating a tremendous
amount of smoke that was lifting to the north. It was merging with
smoke from fires further to the north in the Sierra and then curling
back to the northwest into northwest California where additional smoke
was being generated from fires in this region. The smoke then moved off
the coast and wrapped counterclockwise around an upper level cyclone
west of the San Francisco Bay area. An area of moderate smoke was also
seen associated with fires in southwest Oregon and another in northwest
Oregon. This area of smoke was moving to the north and northeast and
spilling into southern Washington.

Central Canada:
The smoke seen over portions of northern and central Canada this morning
were not detected this evening due to rapid scan operations on the GOES
satellite which greatly limits coverage over northern latitudes. The
smoke is likely still present and making its way slowly to the east as
suggested by air quality smoke models.

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:

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.
