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

.SYNOPSIS...A strong pressure gradient between the Bermuda High
and the Colombian Low will continue to produce strong trade
winds across the central Caribbean, the Atlantic Passages and
the Gulf of Honduras through this morning, with another pulse of
gale-force winds expected offshore of Colombia tonight. Rough to
very rough seas will accompany these winds. The Bermuda high
will weaken and shift eastward late Sun through mid-week,
leading to diminishing trades across the Caribbean. A cold front
is expected to reach the northwest Caribbean Tue morning, with
fresh to locally strong northerly winds filling in behind it.
The front will move eastward and stall from central Cuba to NE
Honduras and through Thu before dissipating.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...Fresh N to NE winds and large swell follow a cold
front extending from 31N38W to 27N55W to 31N65W. High pressure
southwest of Bermuda is supporting fresh to strong winds off the
north coast of Hispaniola and near the approaches to the
Windward Passage, and fresh to strong S winds off northeast
Florida ahead of an approaching cold front expected to move off
the northeast Florida coast Mon night into Tue. Looking ahead,
the front will generally stall from Bermuda to central Cuba by
mid- week, followed by fresh to strong NE winds and rough to very
rough seas.
