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

.SYNOPSIS...A tropical wave moving into eastern Honduras and
Nicaragua will move west of the basin through early Tue.
Elsewhere, Atlantic high pressure building behind the tropical
wave and in combination with low pressure over northern Colombia
will support moderate to fresh trades along with moderate seas
across much of the central Caribbean through Sat. Fresh to
occasionally strong winds are expected to pulse at night off
Colombia and the Gulf of Venezuela. In addition, moderate to
fresh winds will prevail in the Gulf of Honduras through the
forecast period.
