DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 0045Z April 27, 2010

Smoke:
Central Gulf of Mexico:
A large fire yesterday SW of Harmon in Ellis county produced moderate
smoke that can still be seen this evening and has thinned out in density
and width of the line over the last 6hrs or so.  The smoke extends 250km
in a 10km wide SW to NE line now over 650km SE of Galveston, TX or 450km
NW of Merida, MX.  The smoke continues to rapidly move SE.

An unknown though likely smoke/smog can be seen across the eastern Central
GoM ~86W.  This line is about 81km wide in a line that reaches from the
NNW to the SSE just south of 25N85W where the line widens (more like a
L or S shape). The northern portion of this line was moving E while the
central and southern portions were moving SE or even S.  Interestingly,
the northern portion of this area became more dense through midday where
it appeared the source was emitting from the Horizon Oil Platform/Oil
Slick region...even though the rig sunk (Psbl emissions from numerous
ships in the region or bubbling up smoke?)

Yucatan Peninsula/Ext SE Gulf of Mexico:
Remnant smoke from numerous fires over S and E Mexico remain SE of
a former frontal boundary that has shunted SE now extending from the
Tabasco/Bay of Campeche coastline across the Yucatan to Cozumel then over
to Western Cuba to the Florida Keys and Andros Island in the Bahamas.
The smoke is moving NE within the flow affecting the S Yucatan, S Mexico,
Belize into C Cuba.

Unknown:
Florida Atlantic Coast:
An area of unknown aerosol, possibly dust from New Mexico 2 days ago,
can be seen moving E and NE off of Cape Canaveral about 90 miles wide
and 300km long from the Cape toward the NE (in the clear slot of SWly
flow aloft).

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.
