DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0132Z July 31, 2013

North central and Northeast Canada:
Dense smoke from large fires over N Manitoba, NW Ontario, N Alberta and
S NW Territories was emitted over the last few days remains relatively
concentrated downstream of a developing large cyclone over NE Saskatchewan
and N Manitoba... with a portion wrapping around the northern side
across extreme SE continental Nunavut, all of Hudson Bay and across the
northern portion of Quebec reaching far southern Ungava Bay and far N tip
of Labrador.   Some smoke has been pulled southeast across W Quebec on the
western side of the large synopic cyclone over NE of Quebec City...this
is a bit less dense but still at least moderately dense.

Pacific NW and Northern US Rockies:
Copious amounts of thin to moderately dense smoke from the large fires
across Central WA (with some contribution from N ID, NW MT fires) has
filled the central plateau of WA with an arm of smoke moving N and NW
covering Puget Sound and moving toward Vancouver and Victoria in BC under
the influence of a weak coastal cyclone. Predominantly the remaining
thin  smoke moves NE across WA then flattens to due east nearly in line
with the Canadian boarder from WA to N MN, before fanning out with some
moving NE across the Lake of the Woods into SW Ontario as well moving
SE across SD and S MN. The band is about the width of MT wide.

California Valley:
Thin smoke covers the Northern Valley of California as smoke emitted from
the last few days from the Aspen fire has been drawn up under southerly
winds.... flow has shifted a bit from the SW and so moderately dense
smoke can be seen banking up along the western flanks of the Sierras.

Dust/Sand:
The salt flats of W and NW Nevada are being resuspended under strong
Swly flow... the sand/dust is not particularly dense today and extends
about 20-40km NE from each source.   This is also being mixed with
thin to moderate smoke from the central Sierra Fire (Aspen), though at
significantly different elevations.

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.
