NWS National Hurricane Center Miami, FL
1131 AM EDT Sat Aug 26 2023

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

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

.SYNOPSIS...Light to gentle winds, locally moderate in the
S-central and NW Caribbean, and slight seas will prevail across
the basin through the weekend as Hurricane Franklin moves
northward and away from the Caribbean region. A developing area
of low pres in the NW Caribbean is expected to gradually become
better organized through the weekend, as it drifts northward
across the NW Caribbean, Yucatan Channel, and into the eastern
Gulf of Mexico. A tropical depression is likely to form late
this weekend or early next week in the eastern Gulf of Mexico.
High pressure will build modestly to the N of the region Tue and
Wed to bring a return to moderate to fresh trade winds, locally
strong in the central Caribbean.
