DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0130Z August 19, 2014

Canada/U.S:
Extensive cloud cover over much of central and northern Canada, including
where the massive wildfires around Great Slave Lake have been burning
for the past 2 months, is obscuring an accurate assessment of the full
extent of smoke in Canada. The smoke roughly covers southern British
Columbia, the southern half of Alberta, much of Saskatchewan and Manitoba
and southern Hudson Bay before curling to the southeast into southwest
Quebec. The smoke also spills over the border into the northern Rockies
and northern Plains of the US, covering most of Montana, the Dakotas and
Minnesota. The areas of moderate to dense smoke were mostly confined
to a swath from southeast Alberta into northeast Montana, the western
Dakotas and into southern South Dakota. It also extends over southern
Saskatchewan into central and northeast Manitoba into western Hudson Bay.

Northeastern U.S and Atlantic:
Light areas of remnant smoke from the northern Canadian wildfires was
seen along coastal New England and continued eastward into the Atlantic
south of Nova Scotia.

Western U.S:
Multiple wildfire complexes continue to burn in northern California. The
smoke extended to the north across western Oregon and then curved to the
east across Washington and Idaho and then merged with the smoke from the
Canadian fires over Montana. The California smoke also was being drawn
south off the California coast to at least the San Francisco area. The
smoke was mostly light density, with patches of moderate density near
the California and Oregon coasts and a small area of dense smoke over
the complexes.

Gulf of Alaska:
A streak of light density smoke was detected over the Gulf of Alaska
from near Kodiak Island to near Queen Charlotte Island. The origin of
the smoke is uncertain.

Northern Canada:
A streak of light smoke persists over northwest Nunavut and northeastern
NW Territories, extending to the northwest over the open Arctic ocean.

DUST:
A broad area of Saharan dust is currently over much of the western and
southern Gulf of Mexico and the western Caribbean. The dust extends
over the southern half of the Florida peninsula and also is lifting into
southeastern Texas.

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.
