from 07N to 22N between 55W and 64W, the SW N Atlantic S of

Synopsis for Caribbean Sea and Tropical N Atlantic from
07N to 19N between 55W and 64W

.SYNOPSIS...A cold front currently from the SE Gulf of Mexico
and into the central Yucatan Peninsula will move southeastward
into the Yucatan Channel early Thu, then reach from eastern Cuba
to NE Honduras by Fri morning. Fresh to strong winds and rough
seas will immediately follow the front across the NW Caribbean
Thu and Thu night. Winds and seas will diminish late Fri across
NW portions as the front reaches the Windward Passage, then
weakens from Hispaniola to the Honduras-Nicaragua border on Sat.
High pressure building north of the region in the wake of the
front will support fresh to strong NE winds in the lee of
eastern Cuba and across the Windward Passage Fri night through
Sat. These winds and seas will diminish late Sat. Moderate N
swell is moving through the NE Caribbean Passages and adjacent
Tropical Atlantic waters tonight and will gradually subside
through late Thu. Strong trade winds and rough seas will pulse
off the coast of Colombia and the southern coast of Hispaniola
Sat and Sun as the high pressure settles north of the area, and
E of the Bahamas.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...Low pressure SE of Bermuda near 29N62W will drift
southeast and dissipate through Thu. Large northerly swell
dominates the waters W of 60W and will gradually subside through
late Thu. An associated cold front extends from 31N59W to 26N55W
to the central Lesser Antilles. An area of strong to near-gale
force winds, rough to very rough seas, and scattered strong
thunderstorms remains active to the east of the front, N of 20N.
The low pressure and front will gradually shift to the east of
55W Thu through Fri. Farther west, a new cold front will move
off the northeast Florida coast early Thu, and reach from
Bermuda to eastern Cuba by early Fri, from 31N55W to the Mona
Passage by early Sat, then move east of the area Sun. Strong
winds and rough seas will follow this front, then diminish from
west to east as high pressure build eastward along roughly 29N in
the wake of the front.
