DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1600Z JULY 6, 2008

Mid Atlantic Coast:
Extensive cloud cover is hindering a good look at the smoke from the
ongoing fires in the Great Dysmal Swamp and in Hyde county North Carolina.

St. Lawrence Valley:
Some old smoke brought down from fires in Saskatchewan and Manitoba can
be seen moving east from Sudbury Ontario across Monreal in extream lower
Quebec the upper St Lawrence Valley, northern Maine to off the coast of
New Brunswick and Prince Edward Island.


California/Nevada/Oregon/Washington:
Smoke from the numerous fires burning across California covers much of
northern and central California this morning. The thickest smoke was seen
in northern California in the Sacramento Valley and the western slopes
of the Sierra Nevada across Tehama, Butte, Yuba, Nevada and nearby
counties. The smoke was drifting to the south and had reached Yolo
and Sacramento counties. Much of the smoke from the fires in Monterey
and Santa Barbara counties has drifted south off the coast although
some thin smoke was still seen moving to the east into the San Joaquin
Valley. Light to moderately dense smoke from the large fire in northeast
Kern county was lifting to the north across Inyo county and into southern
Nevada. Additional light smoke was seen over northwest Nevada from the
fires in northern California.

A large mass of thin to moderately dense aerosol was seen over much of
Washington and Oregon having moved in from the Pacific. The thickest area
was over eastern Washington and northwest Oregon by mid morning. The
smoke also extended offshore and down the coast to just off the coast
near the Oregon/California border. The origin and type of aerosol is
uncertain but is possibly recirculated smoke from the California fires
that was drawn northwest into the Gulf of Alaska several days ago.

South Central Canada/Northern Plains and western Great Lakes:
An area of thin smoke was seen stretching along the Canadian/US border
from Montana/Saskatchewan east to Minnesota/Ontario. An additional area of
thin smoke with patches of moderately dense smoke was seen over Wisconsin,
Iowa, Illinois, Indiana and Michigan. This smoke was a combination of
residual smoke from the large numbers of fires in northern California
and in northern Saskatchewan.

Alaska and Northwestern Canada:
Two fires continue to burn and produce smoke in eastern Alaska. One fire
was about 55 km to the south-southeast of Fort Yukon and the other about
50 km to the north of Fort Yukon. The amount of smoke actively being
produced by the fires has diminshed substantially overnight but the
smoke from last evening extends to the southwest in a channel between
Fairbanks and Tanana, over McGrath and Aniak and into Kuskokwim Bay. The
An area of moderatley dense to perhaps dense smoke was roughly between
Minchumina and McGrath. An area of thin smoke was also seen in a broad
arc across northern Canada extending from Northwest Territories from
east of Great Slave Lake to east of Great Bear Lake and along the north
slope of Yukon and Northwest Territories.

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.
