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

.SYNOPSIS...Weak high pressure prevails across the Atlantic
along 25N tonight between the Bahamas and 60W and will shift NE
through tonight. High pressure across the NE Atlantic will
gradually build westward along 25N and into the Bahamas Fri
through the weekend, which will strengthen the ridge. This
pattern will support fresh to strong trade winds south of 15N
through the upcoming weekend, gradually expanding westward to
Nicaragua. Winds will pulse to fresh to strong across the Gulf
of Honduras each evening and night through the period. Moderate
trades in the eastern Caribbean and tropical Atlantic will
freshen Thu night into the weekend, with large swell over the
Atlantic waters east of the Windward Islands starting Sat.

waters between northeast Florida and Bermuda early next week.
