Synopsis for Caribbean Sea and Tropical N Atlantic from
07N to 19N W of 55W

.SYNOPSIS...Widespread fresh to strong trades and rough seas
will occur across the southwestern, central and eastern Caribbean
into this weekend. Winds will pulse to gale force offshore of
Colombia tonight into Thu morning, with winds reaching near-gale
force in this area each night Thu through this weekend. In
addition, a long-period E swell will lead to rough seas through
the Atlantic Passages through this weekend. Elsewhere, a cold
front currently extending from western Cuba through northeastern
Honduras will progress slowly southeastward into Thu before
dissipating. Fresh to locally strong NE winds and seas of 8 to 14
ft will occur in the wake of the front, including through the
Yucatan Channel, through tonight. Moderate to fresh NE winds,
pulsing to strong at times, and rough seas will occur in the
northwestern basin through Fri as troughing prevails in the
region. Looking ahead, widespread strong N to NE winds and
building seas are slated to develop across the northwestern
Caribbean by this weekend as a cold front moves through the Gulf
of Mexico. Strong winds and building seas will expand into the
central Caribbean through the weekend.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...A cold front extending from just west of Bermuda to
the NW Bahamas to the Florida Straits will progress eastward
through Thu morning, with strong to gale-force winds and very
rough seas expected in its wake, mainly N of 27N and W of 70W.
Fresh to locally strong SW winds will occur ahead of the front
today. Elsewhere, fresh to strong trades and rough seas will
prevail through the weekend south of 23N. Low pressure is
expected to form off the east coast of Florida on Thu, and
moderate to fresh N to NW winds will occur to the north and west
of the low through Fri morning. The low will strengthen and move
northeastward Fri into Sat, promoting widespread fresh to strong
N to NW winds north of 22N and west of 70W by Fri night. An
associated cold front will trail the low pressure and move
eastward this weekend, producing fresh to locally strong N to NE
winds and rough seas in its wake.
