THRU 0230Z JULY 11, 2005

A large area of smoke visible earlier this morning across northwestern
Canada is not easily discernible this evening. It is possible that it
has dissipated somewhat or a portion of it could be covered by cloudiness.

Canada/North Central US:
Very large fires continue mainly across Saskatchewan Province of west
central Canada. An enormous area of smoke produced by these fires has
spread southeastward across eastern and southeastern Canada toward the
northeastern US. Some of the smoke may soon drift into northern New
England overnight and early tomorrow.

One large fire is noted this evening across northern Baja California which
is sending smoke northeastward in the general direction of southwestern
Arizona. Another fire just south of the Arizona-Mexico border is
producing a smoke plume that is headed toward southwestern New Mexico
and far western Texas perhaps nearing El Paso overnight or early tomorrow.

Evening visible imagery showed an expansive area of haze covering a
large region from the middle Mississippi Valley and central Plains to
the far northern Plains. A concentrated area of what is believed to be
mainly agricultural burns is likely contributing to the overall haze
in the atmosphere. Some smoke from these fires was analyzed in a band
stretching from north central Oklahoma to southern Nebraska.


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.
