Synopsis for Caribbean Sea and Tropical N Atlantic from

07N to 19N W of 55W



.SYNOPSIS...The pressure gradient between a ridge of high

pressure in the Atlantic and lower pressure in the SW Caribbean

associated with the E Pacific monsoon trough will support fresh

to strong trades across most of the central and SW Caribbean.

Winds are expected to pulse to near- gale force off Colombia and

in the Gulf of Venezuela, with moderate to rough seas. Strong

winds will develop over the Gulf of Honduras today and continue

through the weekend. Elsewhere, moderate to fresh winds and

moderate seas will prevail.
