DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 2030Z July 6, 2015

SMOKE:
Alaska/Canada/Central to Eastern U.S:
The tremendous number of large wildfires continue to burn over vast
stretches of northern Saskatchewan and Alberta with additional fires in
southern Northwest Territories and northeast British Columbia. There is a
bit of a break in the fires over the Yukon Territory and eastern Alaska
but another large batch of fires is seen in central Alaska while fires
seen yesterday in southwest Alaska have mostly been beneath thick cloud
cover today from a storm system rotating north across the Aleutians. These
fires are producing an enormous amount of smoke that ranges virtually
unbroken from the far northeastern tip of Siberia across Alaska, southern
Yukon and southwest Northwest Territories and then covers nearly all of
central Canada from the Rockies to Quebec. The smoke has also been drawn
south into the US by a large cyclone over Hudson Bay and covers much of
the northern Plains, the mid Mississippi Valley, The Great Lakes States,
Ohio and Tennessee Valley and the northeast US before exiting off the
New England and mid Atlantic coasts. Cloud cover along a front likely
obscures some of the smoke across portions of the upper Mississippi Valley
and Midwest. While much of the smoke is aloft there are vast stretches
of moderately dense to dense smoke, most notably over the eastern Great
Lakes, over and off the coast of the northeast US, across the Canadian
Maritimes, from northeast British Columbia, north Alberta, Manitoba,
and Saskatchewan southward into the Dakotas/Minnesota, and finally over
a large portion of northern Alaska stretching northwest towards Siberia.

Pacific Northwest:
Wildfires burning in British Columbia yesterday and today continue to
produce smoke that has stretched southward along the British Columbia
coastline and into the Pacific Northwest US including north Washington,
north Idaho, and northwest Montana where additional fires are also
generating smoke. In particular, two very large fires in southwest
British Columbia produced very dense plumes of smoke yesterday that
continue to drift both southwest and east while the fires emit new smoke
as well. Some smoke from the fires to the north has drifted down into
northeast Oregon as well.

DUST:
Gulf of Mexico/Southern U.S/Atlantic Ocean:
An expansive area of Saharan dust continues to be seen over much of the
Caribbean and extending into the western and central Gulf of Mexico. The
dust  spreads to the coastline along southeastern Texas and inland
through central/north Texas, Oklahoma, Kansas, and west Missouri before
disappearing beneath clouds. The exact extent of the dust is difficult
to determine due to the presence of these clouds and the diffuse nature
of the dust in the region. The dust is also seen over southern Florida
and across the Bahamas into the Atlantic wrapping northeastward off the
Eastern Seaboard.

Far North Alaska/Beaufort Sea:
An area of aerosol that appears to be dust from Asia is seen in visible
satellite imagery drifting east across the North Slope of Alaska and
over the Arctic waters where ice cover still exists. This aerosol is
just north of the dense smoke from the Alaska fires.

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.
