.SYNOPSIS...The Bermuda High north of the region will support
fresh to strong E trades across the central and eastern
Caribbean through at least Mon night, with winds pulsing to gale
force off the coast of Colombia mainly during overnight and
early morning hours. Fresh NE winds should develop in the
Windward Passage will persist through Mon, with fresh to strong
winds Sat and Sun. Fresh to strong E trades should develop in
the Gulf of Honduras nightly beginning Sat night. N swell with E
wind waves are producing combined seas of up to 10 ft in the

conditions will prevail through Mon.
