Synopsis for Caribbean Sea and Tropical N Atlantic from 07N to 19N between 55W and 64W .SYNOPSIS...The pressure gradient between the Bermuda High and low pressure over N South America is causing strong trades across the central Caribbean today.

A cold front should reach the Yucatan Channel on Mon afternoon, extend from Cuba to Honduras Tue afternoon, and perhaps move to the SW Caribbean on Wed afternoon.
