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 south-central Caribbean
through Fri. 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 is forecast
to form over the southwestern Gulf of Mexico.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...An elongated area of low pressure offshore the
southeastern U.S coast is producing a large area of disorganized
showers and thunderstorms. Despite strong upper-level winds,
some gradual development is possible while the system moves
northeastward offshore of the southeastern U.S. coast during the
next day or so. Numerous showers and thunderstorms are associated
with this system impacting mainly the waters N of 27N and W of
74W. Gusty winds, higher seas and frequent lightning will be
associated with this convective activity forecast to persist
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. As the low pressure departs, high
pressure will build southward over the western Atlantic beginning
this weekend and into early next week.
