Marine Conditions:

The Caribbean Sea

There is one tropical wave in the Atlantic, and one in the Caribbean.

Scattered moderate convection is noted within 100 nm of the coast of NE Honduras, Nicaragua and northern Costa Rica. A surface trough extends from the Yucatan Channel to northern Honduras, with no significant convection at this time. The surface trough is quite evident in a recent scatterometer satellite pass, showing broad troughiness over the Gulf of Honduras. The remainder of the Caribbean enjoys fairly tranquil weather conditions thanks to a drier environment. Satellite-derived wind data indicate fresh to strong trades in the south-central Caribbean, mainly within 170 nm of the northern coast of Colombia. Gentle to moderate trades are found in the rest of the basin. Seas of 3-5 ft are present in the central and eastern Caribbean, with the highest seas occurring in the south-central portion of the basin. Elsewhere, seas range between 1-3 ft.

For the forecast, Hurricane Sam will move to 13.1N 48.0W this afternoon, 13.5N 49.3W Sun morning, 14.0N 50.4W Sun afternoon, 14.7N 51.5W Mon morning, 15.4N 52.5W Mon afternoon, and 16.3N 53.7W Tue morning. Sam will change little in intensity as it moves to 18.0N 56.0W by early Wed. Meanwhile, moderate trade winds will persist over much of the Caribbean into early next week, while fresh winds prevail over the south-central Caribbean as high pressure builds east of the Bahamas.
