.SYNOPSIS...Fresh trade winds will prevail over the central
Caribbean into early Wed. Winds will pulse to strong speeds in
the south-central Caribbean, and may reach near-gale force
offshore of Colombia late tonight. Rough seas are expected near

waters, rough seas in N swell are expected through late Thu
before seas subside. A cold front will enter the northwestern
Caribbean on Tue, with fresh to locally strong N winds and rough
seas expected in the wake of the front, including through the
Yucatan Channel. The front will weaken and eventually dissipate
