DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0145Z July 19, 2013

US Mid-Atlantic/New England and coastal waters:
A plume of pollutants and haze with mixed smoke can be seen from the
mouth of the Chesapeake Bay to Cape Cod extending eastward to about
40N65W then with a bit more northeasterly motion  toward the Canadian
Maritime Waters off Cape Race.    The smoke was trapped under the upper
ridge from emissions from fires in Manitoba/Saskatchewan from last weekend
and earlier.  Pollutants/haze as been concentrating due to the flow being
generally trapped and increased heat/humidity making it easier to detect
in visible imagery.

E Canada:
Far Eastern Quebec fires are once again producing very dense smoke but
thin to moderately dense smoke from yesterday could be tracked over
Newfoundland and southward moving due east merging with the discussed
pollutants/light smoke described above to the SE of Cape Race.

A narrow ribbon of moderately dense smoke likely from fires in N Ontario
OR N Manitoba from the last few days appears to be concentrated along
a jet streak axis that stretches from Quebec City across the SE Quebec
across the N tip of New Brunswick into the Gulf of St. Lawrence across
Les Iles-de-la-Madeleine to the N tip of Nova Scotia to Cape Race.
This plume is about 20-40km wide.

US Northern Great Plains:
Remnant thin smoke from yesterday's Idaho fire emissions can be seen
moving E and SE  from North-central MN, across the the ND/SD boarder  into
W SD, S MT and N WY around the Big Horn Mtn Range.   Thin smoke across
NE MT and N ND is drifting S and is described below in SW Canada section.

SW Canada:
A large area of moderately dense to dense smoke is moving S across Central
BC from the E Queen Charolette Sound around Aristazabal and Princess Royal
Islands to the point where the BC/Alberta boundary no longer follows 120W
north of McBride, BC.  Due to different flow regimes on each side of the
spine of the Rockies the dense smoke on the Eastern Side is moving SE and
covers nearly all of Alberta and Saskatchewan south of 55N, but north
of 50N; thin smoke continues southward from there into NW MT and N ND.
An arm of moderately dense smoke can be seen across the large Manitoban
lakes where it becomes too cloud covered to be seen.    This smoke
originates from the large output of smoke a few days back across the
Yukon territory with some contributions from AK and NW Territory fires.

California (Norte y Baja):
Large area of thin smoke from the Mountain fire in S California can
be seen covering all of California from Lake Tahoe to Monterey Bay
southward including portions of W and S NV.  Some smoke as being pulled
south across Baja California and coastal Pacific waters and covers even
past the Baja Norte and Baja state boarder; at that point influence of
the large upper low over N Sonora pulls the smoke eastward across the
Sea of Cortez into Southern Sonora.

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.
