DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0300Z June 14, 2010

Northern Plains/Northern/Central Canada:
A massive amount of remnant smoke was observed this evening from numerous
large wildfires that have been burning for several days over northern and
central Saskatchewan and southeast Northwest Territory. The smoke covered
eastern Saskatchewan, all of Manitoba much of northwest Ontario extending
across James Bay, southeast Northwest Territory and southern Nunavut in
Canada and North Dakota and northwest Minnesota in the US. Moderately
dense smoke was dropping into the border area of Minnesota and North
Dakota and extended across Lake Winnipeg and then arced to the northeast
across southern Hudson Bay. Areas of very dense smoke were associated
with the active fires between Reindeer Lake and Lake Athabasca.

Eastern Canada:
Moderately dense to dense smoke from several active wildfires in central
Quebec east of James Bay was moving quickly to the east southeast and had
nearly reached the western edge of the Gulf of St Lawrence by sunset. An
area of light remnant smoke from these fires was moving east across the
open waters of the Gulf of St Lawrence.

Alaska:
Remnant smoke over Alaska was mainly confined to the vicinity of the
Brooks Range and the North Slope. The smoke was mainly light with patches
of moderately dense smoke. A small area of remnant smoke has been drawn
south into the northeast Gulf of Alaska by a cyclonic circulation that
is moving inland over southeast Alaska.

Southeast US:
An area of aerosol was observed over the northeast Gulf of Mexico
extending to the northeast across northern Florida and coastal Georgia
and South Carolina and into the Atlantic. While there may some remnant
smoke in this aerosol it is likely a mix of other aerosols.

Pacific Northwest:
An area of aerosol was seen moving inland over northern California,
much of Oregon and Washington and into northern Idaho ahead of a frontal
system. The source and composition of this aerosol is uncertain, however
an aerosol model suggests this may be long range transport of blowing
dust from Asia.

THE FORMAT OF THIS TEXT PRODUCT IS BEING MODIFIED. IT WILL NO LONGER
DESCRIBE THE VARIOUS PLUMES THAT ARE ASSOCIATED WITH ACTIVE FIRES. THESE
PLUMES ARE DEPICTED IN VARIOUS GRAPHIC FORMATS ON OUR WEB SITE:

JPEG:   http://www.osdpd.noaa.gov/ml/land/hms.html
GIS:    http://www.firedetect.noaa.gov/viewer.htm
KML:    http://www.ssd.noaa.gov/PS/FIRE/kml.html

THIS TEXT PRODUCT WILL CONTINUE TO DESCRIBE SIGNIFICANT AREAS OF SMOKE
WHICH HAVE BECOME DETACHED FROM AND DRIFTED SOME DISTANCE AWAY FROM THE
SOURCE FIRE, TYPICALLY OVER THE COURSE OF ONE OR MORE DAYS. IT WILL ALSO
STILL INCLUDE DESCRIPTIONS OF BLOWING DUST.

ANY QUESTIONS OR COMMENTS REGARDING THESE CHANGES OR THE SMOKE TEXT
PRODUCT IN GENERAL SHOULD BE SENT TO SSDFireTeam@noaa.gov


 


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.
