DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0225Z July 27, 2010

Northwest Territories/Nunavut/Saskatchewan/Manitoba/Ontario/Great
Lakes region:
This evenings satellite imagery continues to indicate an expansive area
of moderate to extremely dense smoke that covers the eastern Northwest
Territories and then extends southeastward through southwestern Nunavut,
northern and northeastern Saskatchewan, northern Manitoba and then
covers much of Ontario and continues into the northern Great Lakes
area of the US.  The expansive smoke plume is from the numerous active
fires throughout northern Saskatchewan and neighboring areas and from
the current and previous fires in the central Northwest Territories.
Widespread cloud cover over a large portion of the area this evening made
the smoke analysis rather difficult and it is quite possible the areal
extent and density of the smoke could be larger than what is depicted.

Southwest Northwest Territories/British Columbia/Alberta/southern
Saskatchewan:
An area of light to moderate density smoke was being wrapped cyclonically
around low pressure over central Saskatchewan and covered portions of the
southwest Northwest Territories, northeast British Columbia and western
and southern Alberta. The source of this smoke was likely the large
number of fires over the southern portions of the Northwest Territories.
This smoke plume then appeared to merge with a light to moderate
density smoke plume over southern British Columbia and southern Alberta.
The source of the latter smoke plume is the wildfire that continues to
burn over southwest British Columbia.

North Dakota/South Dakota/Minnesota:
An area of light smoke that was earlier analyzed over eastern Montana and
the Dakotas, appears as though it has moved east and was detected over
the eastern Dakotas and northwestern Minnesota at sunset this evening.
Widespread cloud cover with the developing thunderstorms over the Dakotas
prevented a more detailed analysis of this area of smoke.  The source
of this smoke is believed to be the Cardinal Creek and Dominic Point
wildfires over western Montana.

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.
