Marine Weather HF Voice Broadcast
NWS National Hurricane Center Miami, FL
955 PM EST Sat Feb 17 2018

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 ATLC from 07N to 19N
between 55W and 64W

.SYNOPSIS...A tight pressure gradient between the W Atlc ridge
along 28N and the Colombian low will continue to support strong
to near gale force tradewinds across the S central Caribbean
through Mon, with nocturnal winds pulsing to gale force off the
coast of Colombia. Reinforcing high pressure will build S into
the region Mon to produce increasing winds and building seas
across the remainder of the Caribbean, and the Tropical N
Atlantic waters through Wed.

SYNOPSIS FOR THE SW N ATLC INCLUDING THE BAHAMAS

.SYNOPSIS...A ridge extending E to W along 28N will retract to
the E Sun and allow a weak cold front to move off the southeast
United States coasts. The front will quickly stall and dissipate
across the northwest waters on Mon. Gentle to moderate winds
will prevail north of the ridge with moderate to fresh winds
expected generally south of 25N, except becoming strong along the
north coast of Hispaniola and the north approach to the Windward
Passage each evening. The ridge will be reinforcing by a
stronger high pressure Mon through Wed to produce strong winds
and high seas across the entire region S of 25N
