DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1530Z JULY 19, 2008

SO2 and Volcanic Ash from Okmok Volcano crossing Northern US/Southern
Canada:
A dense but narrow plume of SO2 was clearly seen in early morning visible
imagery stretching east from the Pacific across south-central Washington,
northern Idaho, central Montana, northwest North Dakota, southern Manitoba
and Ontario and into southeast Quebec before becoming obscured by clouds.
The plume may contain volcanic ash over portions of the US based on
morning PIREPS.

Impact of California Fires:
Moderate to dense smoke covered the vicinity of the Basin Complex in
Monterey County southward into the Pacific as well as northern California
and the southern half of Oregon.  An extensive area of light smoke covered
all of Wyoming, Nebraska, South Dakota and Iowa as well as portions of
Idaho, North Dakota, Minnesota, Wisconsin, Missouri and Kansas.


Northwest Territories/Manitoba:
Large area of smoke of various thicknesses covered the northern two-thirds
of Manitoba, northern Saskatchewan, northern Alberta and the central
Northwest Territories including the northwest portion of Hudson Bay.

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.
