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

.SYNOPSIS...High pressure over the NW Atlantic will build while
it shifts SE to the central Atlantic waters. The pressure
gradient between the associated ridge and lower pressure over NW
Colombia will maintain fresh to strong winds at night offshore
Colombia through Tue. Moderate to fresh NE to E winds are also
expected in the Windward Passage and south of the Dominican
Republic Sat through Sun. Fresh SE winds in the Gulf of Honduras
will reach strong speeds tonight and expand to the remaining NW
Caribbean W of 82W ahead of a cold front forecast to move across
the Yucatan Channel into the NW basin Mon morning. Rough seas
are expected with the strong winds preceding the arrival of the
front. Fresh to locally strong N to NE winds and mainly moderate
seas will be associated with the passage of the front, which is
forecast to reach from eastern Cuba to NE Honduras by Tue
morning, and from the Windward Passage to NE Nicaragua Tue
evening.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...The tail of a cold front stalls from 21N55W to
19N63W. Moderate to fresh NE winds and rough seas to 10 ft are
ongoing N of the front between 55W and 65W. The tail end of the
front will lift N through the weekend while weakening. High
pressure over the NW Atlantic will build while it shifts SE to
the central Atlantic waters through early next week. The
pressure gradient between the associated ridge and the remnants
of the aforementioned front will lead to the development of
fresh to strong winds north of 22N and E of the Bahamas this 
weekend. These winds will support building rough seas across E of
the Bahamas. Looking ahead, a strong cold front will push off 
the SE United States coast early Mon preceded and followed by 
fresh to near gale force winds. The front will reach from 31N68W 
to the Turks and Caicos and eastern Cuba Tue morning, and from 
Bermuda to the Mona Passage Tue night.
