DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0330Z September 16, 2009

North Central US/Central Canada:
Evening visible satellite imagery showed a fairly large area of thin
to moderately dense remnant smoke and haze stretching from Minnesota
and the Dakotas northward through parts of Manitoba, Saskatchewan, and
southwest Nunavut. The main area of moderately dense smoke was observed
over and around Lake Winnipeg. This remnant smoke and haze was being
wrapped around and into an upper low that continues to push northeastward
across Saskatchewan. Active fires in southern Manitoba, North Dakota,
and Minnesota were adding some additional new smoke. A long thin band
of smoke/other aerosols was also seen this evening pushing quickly to
the east toward Hudson's Bay ahead of the main area of smoke and was
extended from southwest Nunavut to just north of International Falls, MN.

Great Lakes Region:
Thin to moderately dense smoke and haze was seen along a cold front
from southern Wisconsin to northern Minnesota where it joined in with
other smoke/haze as described above. The area of smoke was being pushed
southwestward this evening by the frontal boundary. The origin of this
smoke/haze is unknown.

Southwest Canada:
Thin smoke with embedded moderately dense smoke was seen wrapping around
the southwest side of an upper low. This remnant smoke likely came from
fires in British Columbia. Another area of remnant smoke was seen being
lifted across southern British Columbia by the Pacific system and probably
originated from fires in Oregon yesterday.

Mid-Atlantic Coast:
An area of haze, which possibly contains some thin smoke, was seen
stretching eastward from the lower Chesapeake Bay, southeast VA, and
northeast North Carolina out over the waters of the Atlantic. Several
fires were present yesterday in West Virginia, Virginia, and North
Carolina with some that were seen producing smoke yesterday evening.

Gulf of Mexico:
An area of thin to moderately dense remnant smoke was observed lifting
northeastward across the central Gulf of Mexico from recent fires in
the Yucatan region of Mexico.

can be found at the locations listed below.

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.
