309 PM 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. Looking ahead, expect increasing winds and building seas
over the western Caribbean, including the Gulf of Honduras, over
the upcoming weekend as a broad area of low pressure possible
develops over the SW Gulf of Mexico.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...An elongated area of low pressure over the Florida
peninsula continues to produce a large area of disorganized
showers and thunderstorms. Although upper-level winds are
expected to be only marginally conducive, some slow development
is possible while the system moves northeastward offshore of the
U.S. Southeast coast tonight through late week. Unsettled
weather in the form of numerous showers and thunderstorms, with
gusty winds and higher seas, are over most of the western part of
the forecast waters, mainly W of 70W. Expect for little change
with this convective activity through at least Fri. Fresh to
strong southerly winds are expected over the western Atlantic
ahead of this system during the next couple of days.
