DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0245Z June 30, 2014

SMOKE
Eastern Canada:
Little change was noted with the smoke across eastern Canada which was
described in the text narrative earlier today...
A large area of thin to moderately dense smoke from the Boreal Quebec
fire complex continues to drift eastward across the southern Labrador
Strait and northern Newfoundland.   A pocket of particularly dense smoke
can be seen from the northern peninsula of Newfoundland, east across
the Atlantic then turning north toward the southern tip of Greenland
but still south of 55N. Due to the development of a surface cyclone
near 42N 55W... the eastward progression of the smoke was halted even
stagnant across the Gulf of St. Lawrence, allowing areas of increase
density smoke  such as over coastal southeastern Quebec, southwestern
Newfoundland toward northeastern Nova Scotia moving south offshore along
the western side of the cyclone. Thinner smoke can be seen further west
covering New Brunswick, and eastern Maine into the Gulf of Maine.

Western and Central Canada:
Numerous wildfires clustered around the Great Slave Lake in northern
Alberta, northwestern Saskatchewan, and the southern portion of the
Northwest Territories were emitting large quantities of moderately dense
to thick smoke which moved more to the south during the afternoon and
evening farther down into Alberta and Saskatchewan. The southern most
extent of the smoke could not be determined due to cloudiness in the
region. Additionally, a long swath of primarily thin density smoke from
these fires moved in an easterly direction across north central Canada,
the northern portion of Hudson Bay, to as far east as northern Quebec
and the Labrador Sea.

DUST:
Gulf of Mexico/Central US Gulf Coast:
A well defined moderately to dense Saharan Air Layer can be seen across
the entire Western Gulf of Mexico and also spreading to the north covering
much of southeastern Texas, Louisiana, and portions of Mississippi,
Arkansas, and Alabama. The most dense portion of the Saharan dust was
visible over the western and southern Gulf of Mexico including the Bay
of Campeche. Earlier this morning, a 2-3 degree wide west to east band
extended back from the northeastern tip of the Yucatan to central Cuba
and just south of Andros into Long Island in the South Central Bahamas.

Idaho:
A very narrow stripe of blowing dust originated from a point source on
southeastern Idaho(northwestern Bingham County) just prior to 23Z and
spread quickly to the northeast.

AEROSOLS:
West Texas/Southeast New Mexico to the Central Plains:
An aerosol of unknown origin and composition was present in the area
stretching from southeastern New Mexico and southwestern Texas to the
Central Plains.

Earlier this Morning...
Central North American Continent:
Very hazy conditions exist with mixed pollutants cover much of the
central portion of the United States into Canada; embedded smoke from
the San Juan fire may exist within this area that covers OK and the
eastern 2/3rds of TX.   Hazy conditions can be seen through breaks in
the clouds covering MO, IL, IN, W OH,  LP of MI, Eastern WI and becoming
particularly dense again across E Ontario, James Bay, and far W Quebec.

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.
