DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0245Z July 21, 2015

SMOKE:
Central Canada/North-Central U.S:
An expansive area of generally light density smoke remains over much
of central Canada. Smoke is seen back to the northwest across southern
Yukon Territory and southern Northwest Territories, then extending
south-southeastward across northern Alberta, Saskatchewan, Manitoba,
and western Ontario. The smoke is also seen filtering into the U.S. over
eastern North Dakota and northern Minnesota.

Central to Eastern Canada:
Light to moderate density smoke is seen drifting westward across northern
Quebec and over Hudson Bay due to a low pressure system moving over
southern portions of Hudson Bay. The moderate density smoke is generally
focused over Hudson Bay, but light density smoke is seen extending
towards Greenland.

Central Plains:
A small area of separated light density remnant smoke is seen moving
southward over far southern Nebraska and mostly over Kansas.

Northwestern U.S/Southern British Columbia:
An outbreak of wildfires have been seen across much of the Northwestern
U.S, many of which have been producing at least light to moderate density
smoke up until sunset. These fires and related smoke plumes are seen
across central Idaho, northern Oregon, southern Washington, and southern
British Columbia. The heaviest density smoke plumes are seen in western
Oregon, southeastern Washington, and southern British Columbia.

DUST:
South-central to Southeastern U.S:
Areas of Saharan dust are visible across much of the southern  and
southeastern U.S, generally remaining from Texas and extending eastward
towards Alabama/Georgia before becoming difficult to discern due to cloud
coverage/convection occurring across much of the southeastern states.

SMOKE:
Alaska:
An area of light-density smoke from the central Alaskan wildfires is
visible moving eastward in the Bay of Alaska, south of the base of the
Aleutian islands east over Kodiak Island, and as far east as Yakutat, AK.
The full smoke extent cannot be determined due to cloud cover in the
general area.

DUST:
Atlantic Ocean/Gulf of Mexico:
Another surge of Saharan dust is seen moving across the Atlantic towards
the U.S. Its current extent appears to remain offshore of Florida as well
as into central portions of the Gulf of Mexico off of Texas and Louisiana.

AEROSOLS:
East Coast:
An area of unknown aerosols are visible off the Mid-Atlantic coast this
morning moving eastward extending from North Carolina to New Jersey. Its
a possibility that this plume is a mixture of Saharan dust that has been
moving through the east coast as well as remnant smoke coming down from
Canada, and general sulfates.

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.
