THROUGH 1530Z July 1, 2006.

Western and Southwestern US:
The fire in Washington County of southwestern Utah continues to burn
producing a moderately dense batch of smoke which morning visible imagery
shows across southern Utah and northern Arizona. Patches of cloudiness
across Arizona, Utah, and Colorado are making it difficult to see how
far the smoke from this fire may have spread. A small patch of smoke was
observed moving eastward across central and eastern Wyoming. The source
for this smoke cannot be determined.

Canada/Northern US:
Large fires in eastern British Columbia, northern Alberta, northern
Saskatchewan, and northern Manitoba provinces in Canada are responsible
for an extremely large area of smoke which not only covers a good portion
of western and central Canada, but has also been transported by winds
aloft down into eastern Montana, the Dakotas, and Minnesota. While
satellite imagery shows the thickest smoke residing over east central
Saskatchewan Province, the northern half of Manitoba Province, and western
Hudson Bay, some reduction in visibility reportedly due to haze has been
noted across MT, ND, and MN.

Eastern and Southern US:
Visible imagery shows a very large mass of haze across nearly the entire
eastern third of the country as well as the south central region covering
the middle and lower Mississippi Valley as well as the central and
southern Plains. Recent trajectory information shows that it is likely
that smoke primarily from the Canadian fires and possibly also to a
lesser extent from the recent western US fires is contributing to the
hazy appearance noted on satellite imagery across this entire region,
though it is certainly difficult to determine a smoke concentration in
these areas since the smoke has been around for such a long time mixing
with other pollutants present in the region.



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.
