DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0300Z July 8, 2015

SMOKE:
Northern Alaska:
An area of light density remnant smoke was seen in northern Alaska moving
west into the Chukcki Sea ahead of abundant cloud cover over most of
Alaska. This area of remnant smoke originated from wildfires in central
Alaska the last few days.

Canada/Pacific Northwest/Northern Plains/Great Lakes:
An area of light to moderate remnant smoke was observed over British
Columbia moving to the southeast into Alberta with a stream of moderate
smoke moving through southern Alberta into southern Saskatchewan.
Wildfires in southeastern Yukon, northern and central British Columbia
contributed to this area of smoke which has also merged with light to
moderate density smoke over the Pacific Northwest that was produced from
wildfires in southern British Columbia.  From this smoke in the Pacific
Northwest, a band of moderate smoke extended eastward through Montana,
the Dakotas, northern Minnesota, and northern Wisconsin. Heavy smoke
was seen over central Saskatchewan moving south towards the North Dakota
border where it has met up with an area of moderate remnant smoke produced
from wildfires in British Columbia. Light density smoke was observed
over most of the Central Plains and Great Lakes regions where areas were
not obscured by clouds.  Dense smoke produced from wildfires in central
Saskatchewan yesterday was see ahead of a frontal boundary in central
Manitoba and the northwestern border of Ontario moving eastward. Another
area of light density smoke was seen over Ontario and Hudson Bay  and
probably extended further east into eastern Quebec where smoke was
observed in the Gulf of St. Lawrence although clouds from a large storm
system reduced any chance for an observation of smoke in Quebec.

Eastern US:
A larger area of light density residual smoke was seen in the eastern US
spanning from the panhandle of Florida to Maine.  This area of smoke can
be seen out ahead of clouds associated with convection over the Midwest
and Central Plains and originated from Canadian wildfires.

DUST:
Gulf of Mexico/Southern U.S/Atlantic Ocean:
An area of Saharan dust is once again seen in GOES satellite imagery over
the southwest Gulf of Mexico and portions of the western Caribbean. Dust
is not discernible inland over east Texas and the lower Mississippi
Valley, but aerosol models do show that the dust extends as far north
as Missouri, Illinois and Indiana. An arm of dust also extends northward
across the Bahamas and then gently curves to the northeast well off the
coast of the Carolinas.

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.
