DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1530Z July 23, 2014

SMOKE:
Nearly all of the US and Canada remains affected by remnant smoke from
the large boreal fires in NW Territories with some contribution from
Western US fires such as the most prolific producers overnight, over East
central Nevada (along the Utah boarder).   Clear zones include, Alaska,
BC, WA, OR, CA, W ID, W NV, S AZ, the Southeast US from the Mississippi
River through North Carolina including all but the panhandle of FL.
Obviously, more significant smoke is seen within the large area of thin
smoke and will be described below:

Northern Canada:
Very near and downwind (E and ESE) of the boreal fires is nearly opaque
with extremely dense smoke from Big Bear/Great Slave Lake across
SW continental Nunavut, N E Manitoba into far N Ontario and the SW
coastline of Hudson Bay along the axis of the rear-inflow jet to the
developing cyclone over eastern Hudson Bay/W Quebec.    An additional
arm of very dense (though not as opaque) can be seen moving SE from
Great Slave lake covering far NE Alberta, and the northern 2/3rds of
Saskatchewan nearing the NE portions of Lake Winnipegosis in Manitoba,
though this arm is not moving SSE, it appears to be slowly drifting NNE
under stronger southerly flow or remaining somewhat stagnant

Yukon Territory:
Siberian smoke continues to be squeezed between the amplifying ridge
over the NW Territories and the stronger westerly flow across N AK attm.
This is leading to a shearing with the bulk of the moderately dense smoke
moving NE across N Yukon and NW NW Territories into the Arctic Islands
of Canada, but a small portion is squeezed south across SW/S Yukon,
NW BC and the upper portion of SE coastal AK.

Nevada/Northern US Rockies:
Two large fires (one in NE Nye county, the other along the UT/NV in White
Pine county, NV produced moderately dense smoke that has moving N across
E ID and W WY then rotates anticyclonically over the ridge across S MT
into W SD, clipping SW ND and NE WY.

Southern Great Plains:
A large area of murky/hazy aerosols with mixed smoke can be seen very
well in Goes-West across OK/AR/S MO/SE KS and TX.  Some of this area
is moving back toward the west and fading, while the other portion is
stretching E and NE consolidating along the frontal boundary; thinning
out until getting more dense again across the Mid-Atlantic (central PA)
and moving offshore from Long Island and NJ coast.

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.
