THROUGH 1530Z June 07, 2006.

Widespread cloudiness now covers a good portion of the western two-thirds
of Alaska which is preventing any smoke detection across the state
either from the large fire which had been burning in the southwestern
part of the state or from the fires noted recently in Russia. Early
morning GOES-West imagery though did show what appeared to be smoke or a
combination of haze containing leftover smoke in several batches. One area
extended across the Northwest Territories from west of the Great Slave
Lake to the western portion of Nunavut Province. Some of this smoke also
appeared to be spreading southeastward around the western periphery of a
low pressure circulation centered near the southwestern portion of Hudson
Bay. Patches of the possible smoke were observed over the area stretching
from northern Alberta and northern Saskatchewan Provinces southeastward
across Lake Winnipeg and Central Manitoba Province to Ontario Province
just north of Lake Superior. Clouds in the eastern portion of this area
made additional smoke detection impossible. The source region of all of
this possible smoke described above is likely a combination of smoke
from the Russian fires, the large southwestern Alaskan fire, and the
fires noted earlier this week over northern Saskatchewan Province. Much
farther to the east, a large fire over eastern Quebec Province continues
to produce a large area of moderately dense to locally dense smoke which
has spread both westward and eastward, covering region of far eastern
Quebec to the Gulf of St. Lawrence and Newfoundland Island.

US (Texas to Great Lakes region and the Southeast/Gulf of Mexico):
A large area of haze was noted extending all the way from Texas northward
to the Great Lakes region. The large mass of haze also extended from Texas
eastward across the Gulf of Mexico to Florida. Do not have much confidence
that this large mass of haze contains any significant smoke although it is
possible that some small contribution from the smoke spreading southeast
from Canada has entered the northern US. Some small contribution from
smoke is also possible with the haze  across the Southeastern US/Gulf
of Mexico from the fires (particularly the one over Broward County of
southern Florida). Smoke from that particular fire this morning was
moving off to the north and west toward Lake Okeechobee.



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.
