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

.SYNOPSIS...Fresh to strong winds, and moderate to rough seas
are expected over the central Caribbean through Sun morning due
to the pressure gradient between the Colombian low and a modest
western Atlantic ridge. Winds will pulse to near gale-force at
night offshore of northern Colombia. Elsewhere, fresh to locally
strong trade winds and rough seas in large E swell will prevail
over the Atlantic waters, through the Atlantic passages and into
the eastern part of the basin through Mon night. A cold front
will enter the northwestern Caribbean Mon, accompanied by
increasing winds and building seas behind the front. This front
is expected to reach from central Cuba to N Belize Tue evening,
then will begin to stall and weaken through Wed.
