DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1541Z August 25, 2014

Smoke:
Thin smoke can be seen moving south through the central valley of CA from
last night's output from the Happy Camp, Man and July Fire Complexes in
N CA.    The area is concentrated just north of some high clouds and
north of I-80, east of I-5 and west of the high peaks of the Sierra,
though covering the lower flanks.   Moderately dense to dense smoke
covers the valleys west of each complex and thin lower level smoke (above
boundary layer) is drifting SW from the complexes eventually reaching the
coastal area then turning due south offshore along the coast.   Lastly,
middle-level smoke is moving due east across NE CA, NW NV and SW ID but is
mixed with clouds enhanced from a shortwave trof and associated jet streak
so the exact eastern extent is too difficult to determine at this time.

NW Canada:
Northern Territories:
A large swath of moderately dense to dense smoke can be seen covering
nearly all of N NW Territories and continental portions of Nunavut.
This high density is due to reinvigorated output from the numerous vast
boreal fire complexes mainly north of Great Slave Lake (though obviously
some smaller fires are contributing along the Mackenzie river and south of
Great Slave Lake).  This are is generally lifting due north before being
pulled rapidly east under very strong westerly jet flow north of 64N.

Saskatchewan:
A few small complexes in the southern portion of the boreal forests of
Saskatchewan produced moderately dense smoke that is being stretched
north and south under the affects of the large cyclone SW and the jet
described above... this most dense area appears to be centered around
Lake Athabasca... though the bulk does appear to be bound on the west
by the Saskatchewan/Alberta boarder; though thin less organized smoke
appears to be surrounding the larger broad area that extends as far
south as  51.5N (mixing with smoke from BC, see below)

Alberta:
Thin smoke from large fires in central BC can be seen moving over southern
central Alberta mixing with southward moving smoke from Saskatchewan
fires.   Very dense wx cloud cover covers the source fires in BC so only
the eastern extents of the thin smoke plume can be accurately determined
(wx clouds clear out around the eastern slopes of the Rockies).

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.
