DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0200 July 30, 2007


Northern Rockies/High Plains:
A huge area of dense smoke from numerous fires over northern and central
Idaho and western Montana is seen covering all of Montana and much of the
northern two thirds of Idaho and extending into southern Saskatchewan,
southwest Manitoba and northern North Dakota. A finger of this dense
smoke curls to the southeast and drops into northeast Wyoming. Most
of this dense smoke is lofted well above ground level. The most active
fires that are producing the most dense smoke are seen in Idaho, Valley
and Boise counties in Idaho and in Flathead, Lewis and  Clark, Pondera
and Teton counties in Montana. A narrow ribbon of light to moderately
dense smoke extends across southern North Dakota through central and
southeast Minnesota and into northern Illinois.

Additional fires in southeast British Columbia are producing narrow
plumes of moderate to locally dense smoke that is drifting to the
northeast into central Alberta.

California:
Locally dense smoke from the fire complex in western Siskiyou county
in northern California covers much of the western portion of the county
and is just spilling into northern Trinity county. Light smoke has now
spread into Modoc county and into much of south central Oregon.

The long running blaze in central Santa Barbara county has produced a
broad area of dense smoke that extends into Kings and Tulare counties
to the north and to Ventura county to the east. Light to moderate smoke
then continues further north across the entire Sierra Nevada range and
into eastern Oregon. The smoke has also spread south over the eastern
Channel Islands.

A short lived puff of smoke from a blaze in western Riverside county
produced mainly light smoke that is drifting to the east across Riverside.

Western Great Lakes and Ohio Valley:
Residual smoke from fires in northern Canada as well as numerous fires in
northwest Minnesota is seen over eastern Wisconsin, the Upper Peninsula
and western Michigan, eastern Lake Superior and most of Lake Michigan. The
smoke is mainly thin. Another area of smoke extended across much of
Pennsylvania and Ohio before curving to the southwest across central
Kentucky and into western Tennessee. The likely origin of this smoke
was from the northern Canada fires several days ago.

Northwest Canada:
A few fires were observed over the northern Yukon and western Northwest
Territory west of Great Bear Lake. They were producing moderate to dense
smoke that is now drifting to the east.

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.
