DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1630Z July 26, 2007

Northwest US:
Moderately dense smoke from fires across the area is currently
concentrated in northeastern Oregon, southwestern Washington, and Central
Idaho where is is moving into western Montana.

Montana:
A large fire in Lewis and Clark county near Cascade county is producing
dense smoke that is slowly dispersing outward in all directions of
the fire.

Arkansas:
A fire in Clark County is producing a small area of locally dense smoke
traveling north.

Saskatchewan/Manitoba:
Fires in the northern portions of these provinces continue to produce
locally dense smoke plumes moving toward the east.  The complete extent
of the smoke is not known due to to cloud cover in the area.

Smoke can be seen streaming across Manitoba north of Lake Winnipeg, where
it crosses into Ontario and Quebec along with the southern Hudson Bay.

A continued area of dense residual smoke and haze continues to cover
northern Nova Scotia and areas to the west.

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.
