Marine Weather HF Voice Broadcast
NWS National Hurricane Center Miami, FL
515 AM EDT Wed Jun 12 2024

Marine Weather HF Voice Broadcast for the Tropical N Atlantic
from 07N to 19N W of 55W, the N Atlantic from 19N to
31N W of 55W including the 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 W of 55W

.SYNOPSIS...High pressure located NE of the area combined with
the Colombian low and the passage of tropical waves will support
fresh to strong trade winds across the central Caribbean through
Thu night. Moderate to fresh southeast winds are expected over
the northwestern Caribbean likely through Fri as a trough of low
pressure remains over the eastern Gulf of Mexico. Otherwise,
scattered showers and thunderstorms are forecast to continue
across portions of the northwestern Caribbean through the rest
of the week as a surge of tropical moisture persists across the
region.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...Unsettled weather in the form of numerous showers
and thunderstorms, with locally gusty winds and higher seas, are
over most of the western part of the forecast waters as a
stationary front extends from low pressure of 1012 mb that is
north of the area near 32N76W southwestward to 31N80W and to
inland northern Florida. Meanwhile, a broad and elongated area of
low pressure near the west-central coast of Florida continues to
contribute to the coverage of showers and thunderstorms by
sending additional moisture east-northeastward to the offshore
waters around the NW Bahamas and northward from there. This
activity is being further supported by upper-level disturbances
moving from W to E. Expect for little change with this activity
into the end of the week as the low pressure is expected to move
northeastward across Florida and move offshore of the U.S.
Southeast coast within the next day or so. Although upper-level
winds are expected to be only marginally conducive, some slow
development is possible while the system moves offshore of the
U.S. southeastern coast. A trough may linger from near the NW
Bahamas to near 31N75W from mid-week through Fri night. Fresh to
strong southerly winds are expected over the western Atlantic
ahead of this system during the next couple of days.
