Synopsis for Caribbean Sea and Tropical N Atlantic from
07N to 19N W of 55W

.SYNOPSIS...Showers and thunderstorms near 1012 mb low pressure
between Grand Cayman and central Cuba will diminish overnight as
the low pressure weakens to a trough, moves into the Yucatan
Channel Tue, and dissipates Wed. This pattern is resulting in
weaker than normal trade winds over the south-central Caribbean
Tue, except for off Colombia. High pressure will build north of
the area off the Carolinas by mid week, supporting moderate to
fresh NE winds south of Cuba and Hispaniola, and across the
Windward Passage.
