DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0300Z July 5, 2015

SMOKE:
Alaska/Canada/Central to Eastern U.S:
The epic number of large wildfires continue to burn over vast stretches
of northern Saskatchewan and Alberta with additional fires in southern
Northwest Territories, northeast British Columbia and northwest
Manitoba. These fires are producing an enormous amount of moderately
dense to heavy density smoke that ranges across most of central Canada,
over Hudson Bay and into parts of western Quebec. The smoke is seen
extending southward into the central U.S. near the Rockies and northern
Plains, and reaches as far south as northern fringes of Texas and extreme
southern Arkansas. Smoke is seen stretching northeastward over the Ohio
Valley, Great Lakes region and even parts of northwestern Vermont before
extending further over southern Quebec and crossing over New Brunswick
and into the Northwest Atlantic just south of Newfoundland. As mentioned
before much of the smoke is moderately dense with embedded pockets of
heavy density smoke, but cloud cover across some areas, specifically over
central Canada, Quebec, southeastern U.S. and portions of the Northeast,
make the overall extent of the smoke difficult to discern. This also
includes much of Alaska, though smoke from the wildfires occurring
across central Alaska generally is seen from central and eastern Alaska
and moving into the Yukon Territory, with smoke seen further south over
much of British Columbia as well.

Pacific Northwest:
Wildfires burning in Washington, Oregon, and British Columbia continue
to produce smoke that currently appears to be heading eastward towards
the much larger smoke plume associated with the Canadian wildfires. The
areas of smoke further north over British Columbia and along the British
Columbia coast  are likely from fires in Alaska and have been traveling
southward over the last day or two.

Greenland:
A large area of thin to moderately dense smoke is retrograding westward
from Greenland back towards Labrador and eastern Nunavut. This is remnant
smoke from the Canadian/Alaskan wildfires that is several days old which
has become trapped across the Arctic.

DUST:
Gulf of Mexico/Southern U.S/Atlantic Ocean:
An expansive area of Saharan dust is seen over much of the Caribbean
and extending into the Gulf of Mexico. The dust also spreads inland over
southeastern Texas, spreading inland towards Oklahoma and Arkansas where
it likely mixes with long transport smoke from the Canadian wildfires. The
Saharan dust also extends along much of the eastern Florida coastline
as well as the Gulf Coast before turning northeastward across north
Florida and along the Southeastern US coast towards the North Carolina
and Virginia shores before extending further eastward out over the
Atlantic. An area of Saharan dust can also be seen moving north across
the Bahamas and far southern Florida.

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.
