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

.SYNOPSIS...Fresh to strong NE winds will continue over the NW
Caribbean through midday Thu, while fresh to strong E winds will
prevail across the central basin, as a stationary front persists
from the eastern end of Cuba to the Gulf of Honduras. Widespread
rough seas will continue over these areas. Winds and seas will
slowly diminish Thu night into early Fri as the front gradually
dissipates, and high pressure to the N weakens, However, locally
fresh NE winds will continue to pulse in the lee of Cuba and
near the coasts of NW Venezuela and Colombia into Sat. Scattered
to locally numerous showers and thunderstorms will continue over
the southwestern through western Caribbean and coastal zones
through Fri, from the southeastern Yucatan Peninsula to Panama.
Moderate trade winds and moderate seas are expected over the
basin this weekend into Mon.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...A stationary front extends from 31N53W to 24N65W
then across eastern Cuba along 76W. Fresh NE winds will continue
N of the front to 25N between 68W and Cuba today, then moderate
to locally fresh winds will continue through late Fri night as
the fronts slowly dissipate. Large NW swell dominating the
regional waters will produce widespread rough seas to 12 ft with
and ahead the front, that will propagate into the central
Atlantic through Thu night, then move E of 55W on Fri. Seas will
diminish from NW to SE during this time. Elsewhere, a new cold
front moving eastward away from the southeastern U.S. overnight
will lead to moderate to fresh W to NW winds and locally rough
seas N of 29N through Thu night. The cold front will eventually
dive southeastward in the central Atlantic by late week,
supporting fresh W to NW winds and rough seas E of 70W Thu night
and Fri. 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, while weak high pressure
prevails elsewhere.
