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

.SYNOPSIS...The pressure gradient between the Atlantic ridge and
the Colombian low will continue to support fresh to strong
trades across most of the east and central Caribbean through the
week. Winds are expected to reach near gale force off Colombia
and in the Gulf of Venezuela by Thu night. Moderate to rough
seas are expected within these winds. Elsewhere, moderate to
fresh winds and moderate seas will prevail. By late this week,
winds may increase to strong speeds over the Gulf of Honduras
due to the pressure gradient between the Atlantic ridge and a
broad area of low pressure currently located a few hundred miles
offshore of Central America. This system has the potential of
tropical cyclone formation.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...A surface trough persist over the forecast waters,
and extends southwestward from 31N55W to near the Turks and
Caicos Islands. The trough will dissipate today, and the Atlantic
high pressure will then extend westward towards the Florida
peninsula. Under this weather pattern, moderate to fresh trades
along with moderate to locally rough seas are expected south of
25N over the next few days, with gentle to locally moderate winds
elsewhere. Otherwise, fresh to locally strong E winds are
expected N of Hispaniola Wed through Fri.
