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

.SYNOPSIS...Moist southerly flow supports scattered showers and
isolated thunderstorms in the northern Caribbean waters and this
will continue over the next few days. High pressure over the
central Atlantic will support moderate to locally fresh trade
winds and moderate seas across the eastern Caribbean through mid
week. Meanwhile, a weak pressure pattern will maintain moderate
or lighter winds and slight to moderate seas elsewhere through
the forecast period.
