Synopsis for Caribbean Sea and Tropical N Atlantic from
07N to 19N between 55W and 64W

.SYNOPSIS...The intense low pressure system in the central
Atlantic is gradually lifting northeastward away from the area
through the weekend. Large NE swell across the central Atlantic
will move through the Caribbean Passages and Tropical Atlantic
waters through late Sat. The current weather pattern will
sustain NE-E winds across much of the forecast waters. Fresh to
strong pulsing NE-E winds will occur in offshore Colombia into
early next week. Moderate to fresh NE winds, occasionally
pulsing to strong speeds, will affect the Caribbean Passages and
the lees of the Greater Antilles through tonight.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...The intense low pressure system over the subtropical
Atlantic near 32N42.5W, is forecast to accelerate today into the
north Atlantic and strengthen into a powerful non-tropical 
cyclone. Large long-period north to northeast swell will impact 
the Atlantic waters and Caribbean Passages between the 
southeastern Bahamas and the E Caribbean, producing high seas
into the start of next week, with large E swell reaching the
Florida offshore waters N of 26N through Sat. A new low will
develop along 65W and N of 31N by late Sat and move SSE entering
the central Atlantic this weekend. Gale-force winds will develop
along 28N. These conditions will dissipate by early next week as
the low moves quickly E while weakening.
