DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0300Z May 26, 2011

West Central to Northeast Mexico/South Central US/Western Gulf of Mexico:
An large area of thin density smoke covered northern and northeastern
Mexico and a portion of the western Gulf of Mexico during the day. The
smoke also extended northward and northeastward across central and eastern
Texas and even farther to the northeast in a more narrow band along and
ahead of a frontal system over the lower and middle Mississippi Valley
and the Ohio Valley region. Embedded within this large area of smoke was a
region of more moderately dense smoke across the western Gulf of Mexico,
southeastern Texas, and western Louisiana. More patches of moderately
dense to locally dense smoke were also visible closer to the active fires
burning over west central Mexico. This entire area of smoke was mainly due
to seasonal fires that continue to burn over Mexico and Central America.

Southeast US:
An area of thin smoke which was visible earlier this morning was still
observed in satellite imagery over portions of the Southeast and Middle
Atlantic region and extending offshore over the Atlantic. This remnant
smoke is most likely left over from the fires not only occurring in
Mexico and Central America, but also from the fires burning in the
Southeastern US.

Northern Alaska/Northern Territories/Central and Southern Canada/North
Central US:
Large wildfires continue to burn primarily over northeastern Alberta
province in western Canada. Smoke from these fires was spreading to the
southeast reaching as far as southern Ontario Province of south central
Canada and the northern US from North Dakota to the Upper Peninsula
of Michigan and to the northwest extending across northwestern Canada
to northern Alaska and the Arctic. A band of moderately dense to dense
smoke was also visible within the larger area covering northern Alberta
and northern British Columbia provinces as well as central and southern
Saskatchewan province. From there, this band of moderately dense to dense
smoke became much more narrow as it moved southward into North Dakota,
northern Minnesota, Lake Superior, and the Upper Peninsula of Michigan.

SO2 in Central and Eastern Canada:
Satellite imagery showed a ribbon of SO2 from the recently erupting
volcano in Iceland extending southwestward from Greenland into
northeastern Canada, southward over the middle of Hudson Bay, and curving
eastward over northern Ontario province to central Quebec province.

BLOWING DUST IN THE UNITED STATES:
Western and Central Texas:
Blowing dust mixed with smoke from nearby fires was visible moving
southeast across northwestern and western Texas into central Texas. The
source regions for the blowing dust were likely from spots between
Lubbock and Midland.

THIS TEXT PRODUCT IS PRIMARILY INTENDED TO DESCRIBE SIGNIFICANT
AREAS SMOKE ASSOCIATED WITH ACTIVE FIRES AND SMOKE WHICH HAS BECOME
DETACHED FROM THE FIRES AND DRIFTED SOME DISTANCE AWAY FROM THE SOURCE
FIRE..TYPICALLY OVER THE COURSE OF ONE OR MORE DAYS. AREAS OF BLOWING DUST
ARE ALSO DESCRIBED. USERS ARE ENCOURAGED TO VIEW A GRAPHIC DEPICTION OF
THESE AND OTHER PLUMES WHICH ARE LESS EXTENSIVE AND STILL ATTACHED TO
THE SOURCE FIRE IN VARIOUS GRAPHIC FORMATS ON OUR WEB SITE:

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.
