Marine Conditions:

The Caribbean Sea

There is one tropical wave in the Atlantic, and none in the Caribbean.

Aided by an upper-level low extending from eastern Cuba to San Andres Island, convergent trades are triggering scattered showers and isolated thunderstorms south of Hispaniola and along the coast of Panama. Moderate trades and seas near 4 ft exit across the S central basin, while gentle trades and seas at 2 to 3 ft prevail for the remainder of the basin.

For the forecast, Peter will move north of Puerto Rico and the Virgin Islands to 20.3N 65.3W this afternoon, then continue north of the area through mid week, before weakening to a tropical depression and continuing to south of Bermuda by the end of the week. As this occurs, trade winds over the south- central Caribbean will diminish through Thu night.
