DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0400Z June 18, 2010

British Columbia/Alberta/Saskatchewan/Manitoba/Ontario/Northwest
Territories:
An expansive area of light to moderate density smoke covers much of Canada
from northern British Columbia and the southern Northwest Territories
east towards the western shore of Hudson Bay in Northern Manitoba and
then southeast over James bay into northwest Quebec. Within this larger
smoke plume a large area of very dense smoke was detected over northern
Saskatchewan, northern Manitoba, and southeast Northwest Territories. A
large number of wildfires which have been burning for several days in
this region, flared up again this afternoon producing thick smoke plumes
that were spreading southeastward.

Southern Ontario/Southern Quebec/Great Lakes states/Ohio Valley:
Problems with GOES East and West imagery this evening made smoke
detection across eastern Canada and the eastern US particularly
difficult. Nevertheless, a large area of thin to moderate density smoke
was detected from the southern shores of James Bay and covered most of
southern Quebec and southeastern Ontario. By this evening, smoke had
pushed southeastward across Lakes Erie, Ontario, and Huron to cover parts
of Michigan, Ohio, Pennsylvania, and New York. Another area of remnant
smoke stretched from Lake Superior south along the west shore of Lake
Michigan and then southeast to southern West Virginia. Most of this smoke
is believed to have originated from the wildfires burning in central and
southern Quebec, though the smoke further west along Lake Michigan and
Lake Superior may have come from fires in the southwest the past 2-3 days.

Southeast US and Mississippi River Valley:
A good deal of unknown aerosol created a very hazy look off the southeast
coast, south of the Florida panhandle, and over Mississippi, Alabama,
and Georgia. In addition, what is believed to be thin to moderate density
smoke was mixed in with other aerosols from Arkansas northward across
east Missouri, west Illinois, and into southeast Iowa. Much of this smoke
appears to have either originated from fires along the Mississippi River
or it may have drifted east from the fires in the southwest the past
few days and is now being drawn northward.

Front Range/Central and Northern Plains:
An area of what is believed to be suspended/blowing dust extended from
the Front Range area of Colorado and northeast New Mexico along a frontal
boundary into northwest Iowa and southern Minnesota. Dense smoke from
a large wildfire in Colorado was also contributing to aerosols over the
High Plains.

Southern California/Southwest Arizona:
Smoke from active fires burning south of the Salton Sea in southern
California and at the northwest corner of the Gulf of California was
seen this evening spreading out eastward into southwest Arizona.

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.
