.SYNOPSIS...High pressure N of Bermuda Island will continue to
support strong to near gale-force NE to E winds offshore
Colombia through late Wed along with moderate to rough seas. The
high pressure will lift N and then SE towards the central
Atlantic subtropical waters, which will keep mainly moderate to
fresh trades across the central and eastern Caribbean Wed night
through Thu night, and gentle to moderate easterly winds the
remainder of the forecast period. Moderate to fresh trades and
moderate to rough seas will prevail over the tropical Atlantic
waters and passages through Sat night. Otherwise, pulsing fresh
to strong E winds are forecast in the Gulf of Honduras from late
Wed through Sat night.
