Marine Conditions:

The Caribbean Sea

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

The eastern extension of the E Pacific monsoon trough and abundant moisture results in scattered moderate to isolated strong convection within 130 nm of the coast of Nicaragua, Costa Rica, Panama and NW Colombia. The rest of the Caribbean is dominated by a fairly dry weather pattern.

A modest north-south pressure gradient persists in the south-central Caribbean between a broad Colombian Low and weak ridging north of the basin. Recent scatterometer satellite data indicate that fresh to strong trades are occurring within 200 nm of the north coast of Colombia and 70 nm of the coast of NW Venezuela, encompassing the Gulf of Venezuela and the waters surrounding the ABC islands. Gentle to moderate trades prevail elsewhere. Seas are 4-6 ft over the south-central Caribbean and 2-4 ft elsewhere.

Looking ahead, Hurricane Sam is near 13.8N 49.7W 943 mb at 5 AM EDT moving WNW at 7 kt. Maximum sustained winds 125 kt gusts 150 kt. Sam will move to 14.3N 50.6W this afternoon, 15.0N 51.8W Mon morning, 15.8N 52.9W Mon afternoon, 16.6N 53.9W Tue morning, 17.5N 55.0W Tue afternoon, and 18.4N 56.3W Wed morning. Sam will change little in intensity as it moves to 20.8N 59.3W by early Thu. Meanwhile, moderate trade winds will persist over much of the Caribbean into early next week. Fresh winds will prevail over the south-central Caribbean as high pressure builds east of the Bahamas through midweek.
