DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0245Z September 9, 2013

Central and South Central US:
The area of possible leftover smoke remnant smoke from both the large
Western US fires(especially the east central California Rim Fire) and
much smaller seasonal burning over the the Central Plains and the lower
Mississippi Valley was barely visible late this afternoon. This possible
remnant smoke which is trapped under the large ridge of high pressure in
this region may also contain other atmospheric pollutants so the amount
of smoke leftover here is unknown.

Western US:
The Rim Fire in east central California continues to emit significant
quantities of smoke. Moderately dense to thick smoke covers a portion
of central California and western Nevada with thinner smoke surrounding
the area. In addition, a large dense smoke plume was visible from a fire
over west central California, approximately 30 miles to the east-northeast
of San Francisco.

Blowing Dust in Southern Oregon and Western Nevada:
Very small thin streaks of blowing dust were observed around 01Z
emanating from source regions in south central Oregon (42.8N 120.8W)
and west central Nevada (39.8N 118.5W). The Oregon dust plume was moving
quickly to the south while the Nevada plume moved to the southeast.

Canada:
A number of fires over northern Saskatchewan and east central Manitoba
were responsible for a rather large area of thin density smoke which
extended from northern Saskatchewan to northwestern Ontario. A smaller
patch of moderately dense to locally thick smoke was located within this
batch of thin density smoke over northeastern Manitoba. Another patch of
leftover thin density smoke, possible from the Rim Fire of California,
was visible over Alberta.

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.
