Marine Conditions:

The Caribbean Sea

There are two tropical waves in the Atlantic, and two in the Caribbean.

An upper level trough off the SE United States extends to the NW Caribbean Sea allowing for scattered showers and isolated thunderstorms from the coast of Colombia to Hispaniola, between 71W and 76W. A surface trough extends from southern Florida to the Gulf of Honduras and a few shallow showers are seen near the trough axis. The rest of the basin remains fairly quiet outside of the tropical wave in the E Caribbean previously described in the Tropical Waves section. Fresh trades were noted overnight within 150 nm of the coast of NE Venezuela, including the waters surrounding the ABC islands. Moderate or weaker trades prevail elsewhere. Seas of 3-5 ft are occurring in the E, central and SW Caribbean, while 1-3 ft are present elsewhere.

For the forecast, a tropical wave along 65W is approaching the Virgin Islands and Puerto Rico. This wave will continue to bring active weather across the extreme NE Caribbean and adjacent Atlc waters today. Northerly swell will subside across the regional Atlc and Caribbean passages through tonight. Low pres is expected to develop E of the southern Bahamas on Thu and drift eastward into the weekend. This will weaken the pressure gradient across the Caribbean basin leading to tranquil marine conditions.
