DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0400Z May 16, 2012

Central and Eastern Canada and from the Great Lakes into Texas:
The large area of high level remnant smoke (some of this smoke has
been detected 11 to 12 km high in the atmosphere) continues to slowly
makes its way eastward across North America this evening. Mainly light
smoke was seen extending from northern Saskatchewan and Manitoba south
southeastward into southern Ontario, Upper Midwest and Great Lakes states
as it wraps into a low pressure area northeast of Lake Superior. A
patch of moderately dense smoke was over northern Wisconsin and the
upper peninsula of Michigan and vicinity.

Another branch of the smoke was seen over southern Quebec and the St
Lawrence valley back to the southwest across the eastern Great Lakes,
through Ohio and the Ohio Valley into Arkansas and east Texas and
possibly along the Louisiana Gulf Coast. Much of this ribbon of smoke
was moderately dense and also at high levels of the atmosphere.

Alaska:
An area of remnant smoke from the fires in Asia was seen extending along
a northwest/southeast axis from western Alaska into the northern Gulf
of Alaska.

Arizona:
Three large wildfires continue to burn this evening in the mountains of
central Arizona. They are all generating smoke plumes that are moving
to the north northeast. The largest/thickest smoke is coming from the
Sunflower fire in Maricopa county and is producing areas of very dense
smoke.

Northwest Mexico:
A broad area of light to moderately dense smoke covers much of Sonora,
southwest Chihuahua, Sinaloa and western Durango.

Blowing Dust:
Southwest Nevada/Southern California:
An area of light blowing dust was seen moving south along the border
area of California/Nevada. Additional dust may be present along the
Nevada/Utah border area but extensive cloud cover is hindering detection.

Previous discussion:

Yukon/Northwest Territories through Central/Eastern Canada/US:
A very large and very expansive area of high-level remnant smoke can be
seen again this morning across a vast area from extreme northern Yukon
and the Northwest Territories , extending southeast through much of
central and eastern Canada and then into the Plains and Midwest/Great
Lakes region of the U.S. This smoke is being generated from the numerous
wildfires currently burning through portions of southern Siberia.

While most of this smoke is light in nature, there are pieces that are
moderately dense. Specifically, from northern/central Texas northeastward
through the Midwest and eastern Great Lakes there is a band of more
moderate smoke slowly moving eastward/southeastward. Further to the
north through the northern Plains and southern/central Canada there are
additional areas of moderately dense smoke.

Central Arizona:
An area of remnant smoke can be seen through central and western Arizona
this morning and early afternoon. This is from the 3 large fires burning
across this region over the past few days.

Northern Mexico:
Numerous fires continue to burn through Sonora, Chihuahua,Sinaloa and
Durango over the past several days and are producing a rather large area
of new and remnant smoke throughout this region.


Blowing Dust Nevada/California:
An area of remnant blowing dust that was seen in last evening's imagery
can be seen moving towards the west/southwest this morning through
portions of northwestern Nevada and into northeast/north-central
California.

THIS TEXT PRODUCT IS PRIMARILY INTENDED TO DESCRIBE SIGNIFICANT
AREAS SMOKE ASSOCIATED WITH ACTIVE FIRES AND SMOKE WHICH HAS BECOME
DETACHED FROM THE FIRES AND DRIFTED SOME DISTANCE AWAY FROM THE SOURCE
FIRE..TYPICALLY OVER THE COURSE OF ONE OR MORE DAYS. AREAS OF BLOWING DUST
ARE ALSO DESCRIBED. USERS ARE ENCOURAGED TO VIEW A GRAPHIC DEPICTION OF
THESE AND OTHER PLUMES WHICH ARE LESS EXTENSIVE AND STILL ATTACHED TO
THE SOURCE FIRE IN VARIOUS GRAPHIC FORMATS ON OUR WEB SITE:

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.
