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 Fri, from the southeastern 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 31N54.5W to 26.5N62W,
where it becomes stationary and continues into southeastern Cuba.
Fresh to locally strong NE winds will occur in the wake of the
front north of the Greater Antilles to 25N through late tonight,
with locally 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 25N between 55W and
67W through late tonight. Seas will diminish from northwest to
southeast Thu 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 this evening
through Thu. 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.
