.SYNOPSIS...Fresh to strong E winds will occur over the central
Caribbean, including in the Gulf of Venezuela, through Tue

pressure over the south-central basin, a tropical wave moving
through the western Caribbean and a cold front to the north.
Rough seas will occur near and to the west of the strongest
winds. Elsewhere, fresh to locally strong NE winds will occur in
the lee of Cuba and through the Windward Passage Tue evening
through Wed in the wake of a cold front moving through the
northwestern basin. Looking ahead, mainly moderate trade winds
and moderate seas are expected over the Caribbean Wed night
through the rest of the week.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...Moderate to locally fresh S to E winds are expected
east of 75W today as an increasing pressure gradient develops
between high pressure in the central Atlantic and a cold front
moving southeastward through the Florida Peninsula. This cold
front will progress into the central Atlantic this week, leading
to moderate to locally fresh S to SW winds and rough seas ahead
of the front. In the wake of the front, expect fresh to strong N
to NW winds and rough seas through late Tue. Residual rough seas
will prevail over the waters east of 65W through Thu, and will be
reinforced by a new NW swell on Fri. Elsewhere by midweek,
moderate to locally fresh NE winds are expected over much of the
waters as the front slowly weakens.
