DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0230Z June 19, 2015

SMOKE
Alaska/Yukon:
An area of light density remnant smoke was observed over the coastline
of southern Alaska and the Gulf of Alaska.  This area of remnant smoke
originated from wildfires in southern Alaska and western Yukon. Wildfires
in southeast Alaska and the western portions of the Yukon Territory
continue to produce light to moderate density smoke and have contributed
to the pool of remnant smoke to the south.  A wildfire northeast of
Whitefish Lake in south-central Alaska was producing a heavy density
smoke plume which was moving to the south.  A low pressure system off
the coast of British Columbia was pulling the majority of this smoke to
the south and southwest.

Alberta/Ontario/Manitoba/Hudson Bay:
A broad area of light density remnant smoke was observed over eastern
Alberta, Manitoba, western Ontario, and the western portions of Hudson
Bay.  Aerosol that is believed to be remnant dust is likely mixed in with
this area of smoke.  The cloud cover in western Canada limited the ability
to detect the full extent of this area of smoke and dust to the west.

Northwest Territories/Alberta:
Wildfires in the southern portions of the Northwest Territories
and northern Alberta continue to produce light to moderate density
smoke. Cloud cover partially obscures the movement of these areas of
smoke, although a wildfire southeast of Great Slave Lake can be seen
emitting a heavy density smoke plume to the south.

Southwest US:
A large wildfire in southern California, called 'Lake Fire', was producing
a significant amount of dense smoke that fanned out into the eastern
portions of Arizona, and as far north as southeast Utah.  'Lake Fire'
has burned over 10000 acres in the San Bernardino Mountains of southern
California since yesterday. Several wildfires in central Arizona that
have continued from yesterday have produced light to moderate density
smoke plumes that are moving to the east to the New Mexico border.

Southeast US:
An area of thin smoke is seen off the coast of the Southeast US. The
smoke originates from agricultural burns that have been taking place
in the Southeast US and Lower Mississippi Valley regions over the last
couple of days. There also appears to be elevated dust mixed with the
area of smoke and the entire plume of aerosols is drifting east/southeast.

DUST
Gulf of Mexico/South-central US:
A large area of Saharan dust was moved west from the Caribbean into
the Gulf of Mexico before being pulled northward across the western
Gulf by Tropical Depression Bill with the remnants of Bill now over
southwestern Missouri. The optically thick dust appears to extend north
over the eastern portions of Texas, Louisiana, Mississippi, and eastern
Arkansas though cloud cover likely obscures some of its extent.

THIS TEXT PRODUCT IS PRIMARILY INTENDED TO DESCRIBE SIGNIFICANT AREAS
OF 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.
