THROUGH 1700Z June 20, 2006.

Southwestern and Central US:
Smoke was quite widespread early this morning across portions of
the southwestern and central US. At least 6 major fires, which were
responsible for much of the smoke, were noted over the region including
southern California, Arizona, southern Colorado, and New Mexico. The
large fire in Santa Barbara County of southern California was emitting
a mainly thin to locally moderately dense area of smoke which spread
generally in an eastward direction into southern Nevada. In Arizona,
fires in northern Coconino and along the Coconino/Yavapai County border
were producing thin to moderately dense smoke which was moving in a
northeasterly direction. The northern Coconino fire was responsible for
more smoke than the southern one and also contributed to a much larger
batch of smoke which moved across the region stretching from Utah across
Colorado and southern Wyoming into the Central Plains. The biggest smoke
producing fire noted this morning was in Catron County of southwestern
New Mexico. It was producing a locally very dense batch of smoke which
spread eastward during the morning. It also was responsible for a much
larger mass of smoke which covered a good portion of New Mexico and also
southern Colorado. Smoke from this fire along with other significant
fires noted near the Colfax-Mora County border of northeastern New Mexico
and near the Huerfano-Costilla County border of southern Colorado had
combined and fanned out as it moved northeastward across portions of the
central and southern Plains. Smoke was analyzed as far east as Missouri,
although cloudiness present over the middle of the country made additional
smoke detection difficult. Satellite imagery showed haze even farther
to the east across the Ohio Valley and Mississippi/Tennessee Valley,
but it is not known whether any of it can be directly linked to smoke.

Visible imagery this morning showed a patch of mostly thin to possibly
locally moderately dense smoke from a fire in the west central portion
of the Yukon Province of northwestern Canada, very close to the Alaska
border. The smoke was spreading mainly in a northerly direction across
eastern Alaska and the northwestern Yukon Province. Another region of
possible detached smoke stretched from northwestern British Columbia
Province into the southwestern portion of the Yukon Province. The source
region for this possible smoke was unknown. A very long but relatively
narrow swath of thin to moderately dense smoke extended from near Lake
Athabasca close to the Alberta-Saskatchewan Province border southeastward
almost to northern Minnesota and Lake Superior. This smoke was believed
to have originated primarily from fires over northern Alberta and northern
Saskatchewan Provinces in western Canada.



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.
