DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1902Z August 08, 2010


Numerous fires across Saskatchewan continue to emit copious amounts smoke.
The smoke covers a large portion of Northern North America described
in areas below.  Smoke from the British Colombia fires are beginning to
mix into the overall smoke coverage.

Central Canada:
Very dense smoke covers the source regions of Saskatchewan but Sly
flow is pulling the smoke NW to cover nearly all of NW Territories from
Great Slave to Great Bear Lakes eastward including NW Nunavut. Moderate
smoke covers the rest of Saskatchewan and thins out across MT and S
Alberta...this smoke is moving NE and is likely from the BC fires over
the last few days.  This area is merging with Saskatchewan source smoke
across all of Manitoba.

S Ontario to Newfoundland:
Strong westerly flow in the jet across the southern side of large polar
vortex over E Hudson Bay and N Quebec is pulling the Saskatchewan smoke
from a broad area of thin smoke over SW Ontario across N Lake Superior.
It is in this region the smoke begins to become more dense and compacted
in a narrow ribbon across E Ontario (S of the lake/woods region but N
of the urban centers) across extreme SW Quebec affecting upper levels
over Ottawa, Quebec City and Montreal on its way across N Maine, New
Brunswick, PEI and across Newfoundland.

Newfoundland and US East Coast/Maritime:
Smoke across Newfoundland is a combination from the aforementioned jet
but also a southern airmass that is also elongating from SW to NE from
North Carolina/Virginia through the Delmarva well south of Nova Scotia
but connecting up near Cape Race and E Newfoundland.  This smoke is
likely from output earlier in this week and last weekend.

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:

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.
