325 AM EST Thu Nov 28 2019

Marine Weather HF Voice Broadcast for the Tropical N Atlantic
from 07N to 22N between 55W and 64W, the SW N Atlantic S of
31N W of 65W including Bahamas, and the Caribbean Sea.

Seas given as significant wave height, which is the average
height of the highest 1/3 of the waves. Individual waves may be
more than twice the significant wave height.

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

.SYNOPSIS...A moderate pressure gradient south of the Bermuda
High will be forcing strong to gale force winds across the S
central Caribbean and to near the coast of Colombia through the
morning. A large extratropical cyclone east of the mid-Atlantic
states will reduce the gradient through Mon, weakening the NE
tradewinds to fresh breezes or less across the Caribbean. On Sat
large N swell will begin impacting the offshore Atlantic waters
east of the Lesser Antilles and continue through at least Mon
night.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...Weakening high pressure over the area will shift 
eastward through this morning in response to an approaching cold
front. This cold front will quickly move across the area through
Fri with enhanced NW to N wind building in behind the front.
Associated large NW to N swell will spread across the area Sat
and diminish by early Mon. After winds become quiescent on Sat
to early Sun, another cold front will reach the far NW waters
Sun night and move across the area through Mon. Strong to
possibly gale force winds are expected on either side of the
front northeast of the Bahamas early next week.
