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

.SYNOPSIS...Fresh to strong NE winds will occur over the central
and northwestern Caribbean through Thu morning as a frontal
boundary stalls over the region. Widespread rough seas are
expected over this area, with locally very rough seas possible in
the Gulf of Honduras. Winds and seas will slowly diminish Thu
night into early Fri as the front dissipates, though locally
fresh NE winds may continue to pulse in the lee of Cuba and in
the far south-central Caribbean into Sat. Heavy rainfall will
continue over the southwestern through west-central Caribbean and
coastal zones through Thu, from the Yucatan Peninsula across
Central America to Panama. Moderate trade winds and moderate seas
will occur over the basin by this weekend.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...A cold front extends from 31N56.5W to 25.5N65W,
where is becomes stationary and continues into southeastern Cuba.
Fresh to occasionally strong NE winds will occur in the wake of
the front north of the Greater Antilles to 25N through late
tonight, with occasionally fresh winds continuing through late
Fri night as the fronts slowly dissipate. Widespread rough seas
will expand eastward into the central Atlantic through Thu, and
very rough seas of 12 to 15 ft will be possible north of 23N
between 55W and 71W through late tonight. Seas will diminish from
northwest to southeast into Fri. Elsewhere, a cold front pushing
off the southeastern U.S. later today will lead to moderate to
fresh W to NW winds and locally rough seas north of 29N by this
evening. The cold front will eventually dive southeastward in the
central Atlantic by late week, supporting fresh W to NW winds
and rough seas east of 70W by Thu night. Looking ahead, a series
of cold fronts passing north of the region this weekend will lead
to strengthening winds and building seas over the northern
waters.
