DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1715Z June 17, 2015

SMOKE:
Alaska/Yukon:
Areas of thin smoke are visible over a majority of the coastal areas
of southern Alaska as well as farther inland over southeast Alaska/far
southwestern Yukon Territory in Canada.  Several large wildfires have
contributed to this area of smoke including the Sockeye fire (in Willow,
AK), Tanana Slough fire in eastern Alaska, Card Street fire (on the
Kenai Peninsula of AK), and Can Creek fire (near Lime Village, AK) along
with additional fires in southwestern Yukon. Area of remnant smoke is
generally drifting to the west-southwest as it is pulled offshore by
Gulf of Alaska low pressure system.

South Central Canada/North Central US:
A large area of thin remnant smoke is stretches across much of south
central Canada from James Bay west-southwest to southern Saskatchewan
with some of the smoke extending southward across the US border as
well covering parts of northern Minnesota, northern North Dakota, and
northeast Montana. Some moderately dense smoke was observed over southern
Saskatchewan/northeast Montana as well. Thick cloud cover over central
Manitoba, central Saskatchewan, and southern Alberta may be obscuring
additional smoke. This remnant smoke originates from the wildfires that
had been burning for weeks in British Columbia, Alberta and Saskatchewan.

Southern British Columbia:
A small area of aerosol between the mountain ranges of southern British
Columbia is believed to be smoke from a wildfire north of Vancouver. The
smoke was moving eastward.

Canadian Maritimes/Northeast US:
Portions of a plume of thin remnant smoke are seen moving east/southeast
between areas of cloud cover along the back edge of a low pressure system
moving through the Canadian Maritimes/North Atlantic. The smoke is seen
over the Gulf of St. Lawrence between Newfoundland and Anticosti Island
and from the southeast coast of Nova Scotia southwestward across the
North Atlantic waters to southern New England/Long Island. This remnant
smoke is believe to be from fire activity in western Canada and is likely
several days old.

Southeast US:
A moderately sized area of thin smoke is seen drifting south/southeast
along and off the coast of the Southeast US, covering coastal portions
of Georgia, South Carolina, and North Carolina. The smoke originates
from agricultural burns that have been taking place in the Southeast US
and Lower Mississippi Valley regions over the last couple of days. There
may also be some elevated dust mixed with the area of smoke.

DUST
Gulf of Mexico:
A large area of Saharan dust continues to be visible this morning
moving west from the Caribbean into the Gulf of Mexico before being
pulled northward across the western Gulf by Tropical Depression Bill,
now over north Texas. The optically thick dust appears to extend north
over coastal Texas, Louisiana, southwest Mississippi, and southern
Arkansas though cloud cover likely obscures some of its extent.

Midwest US:
An area of aerosol that is believed to be mostly elevated dust could be
seen over parts of southern Minnesota, northwest Iowa, eastern South
Dakota, and northeast Nebraska this morning through a break in the
clouds. The origin of this possible dust is not entirely clear based on
aerosol models.

Northwest US:
An area of aerosol seen along the coasts of Washington, Oregon, and
northwest California is thought to be elevated dust from Asia.

Central Canada:
Areas of aerosol are seen over northern Manitoba, southeast Nunavut,
and central Hudson Bay as well as stretching from central Saskatchewan
westward across Alberta to northeast British Columbia. Aerosol was also
seen drifting south across the Northwest Territories near Great Slave
Lake and northern Alberta. Most of this aerosol is thought to be elevated
dust that likely has an Asian origin. Most of the dust is being pulled
southward across Canada by a large weather system.

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.
