Marine Weather HF Voice Broadcast
NWS National Hurricane Center Miami, FL
442 PM EDT Thu Oct 27 2022

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 deep layered upper trough N to S across the
central Caribbean will lift northward into the Atlantic Sun. A
tropical wave along 69W continues to interact with this feature
to produce scattered to numerous thunderstorms between 64W and
69W this afternoon. The tropical wave will move slowly W through
the weekend. An area of low pressure is expected to form over
the eastern Caribbean Sea this weekend, possibly related to the
southern portion of an existing trough of low pressure over the
area. Environmental conditions are forecast to be conducive for
gradual development, and a tropical depression could form early
next week while the disturbance moves generally westward or
west- northwestward over the central Caribbean Sea.This system
has a low chance of development in the next 48 hours and a
medium chance in the next 5 days. Expect scattered showers and
thunderstorms to continue through the weekend with the trough
and potential developing low.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...Scattered to numerous showers and thunderstorms 
persist across the Atlantic waters between 62W and 70W, 
supported by a deep layered upper trough along about 70W. At the
surface, a trough of low pressure stretches from Hispaniola 
northward along 69W-70W. These features are expected to remain 
nearly stationary through Sat and maintain active thunderstorms 
to the E. A surface low pressure system is forecast to emerge 
along the northern portion of the trough axis tonight, and a 
subtropical depression could form during the next day or so
while the system moves northward over the western Atlantic. By 
late Saturday, upper-level winds are forecast to become less 
conducive for development, and the low is expected to begin 
interacting with an approaching frontal system. This system has a
medium chance of development in the next 48 hours and 5 days. A 
strong frontal system to the north of the area will interact with
the low and could bring fresh to locally strong winds and NE 
swell with it Fri night through the weekend west of 70W.
