Marine Conditions:

The Caribbean Sea

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

Scattered moderate to isolated strong convection is noted along the monsoon trough and tropical wave in the SW Caribbean S of 14N between 75W and 83W. Elsewhere, a complex of thunderstorms are moving near the Cayman Islands. Isolated thunderstorms continue to move across the waters near Hispaniola and Puerto Rico. Overnight scatterometer data depicted a large area of strong to locally near gale- force trades in the south-central Caribbean, especially within 190 nm of the NW coast of Colombia and the Gulf of Venezuela. Seas in the area are 6-9 ft. Moderate to fresh trades are noted in the north- central and E Caribbean and the Bay of Honduras with seas of 4-6 ft. Gentle to moderate trades and seas of 2-4 ft are found elsewhere in the basin.

For the forecast, the Atlantic ridge will continue to build westward across the Caribbean, bringing an increase in the trade wind flow this weekend. Fresh to strong winds will occur offshore Colombia and in the Gulf of Venezuela, mainly at night through Sun. Fresh to strong winds are also likely in the late evening in the Gulf of Honduras through Sun. Scattered showers and thunderstorms across the NW Caribbean are expected to reduce in coverage later today.
