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 pulsing fresh to
strong trades and rough seas across the south- central Caribbean
through the forecast period. Fresh E winds are expected across
the Gulf of Honduras, mainly at night, into early next week,
pulsing to locally strong Sun night. Moderate to fresh winds and
moderate seas are expected in the eastern Caribbean through the
weekend while gentle to moderate winds and slight to moderate
seas will prevail NW portions.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...The Atlantic ridge will dominate most of the forecast
area through Wed producing a gentle to moderate anticyclonic
flow, except for moderate to fresh E to SE winds off the northern
coast of Hispaniola through Tue, then pulsing winds to fresh to
strong speeds are expected thereafter. A surface trough is
forecast to develop offshore Florida on Mon and drift westward
across Florida into the Gulf of America on Tue accompanied by
active weather. The pressure gradient between the ridge and the
surface trough will support moderate to fresh S to SE winds
across the NW zones Tue through Wed.
