Marine Weather HF Voice Broadcast for the Gulf of Mexico

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 the Gulf of Mexico

.SYNOPSIS...A stationary front extends from 24N80W to 23N90W, to
a 1014 mb low pressure center that is near 21N94W, and curving
to the coast of Mexico near 19N91W. Strong high pressure is
present to the NW and N of the front. A tight pressure gradient,
between the high pressure and the front, is supporting strong to
near gale-force NW to N winds in the far SW corner of the Gulf
of Mexico. These winds will diminish to strong winds on Tuesday,
and to moderate winds on Wednesday. Strong northeast to east
winds will cover almost the entire Gulf of Mexico on Tuesday and
Tuesday night, and the far eastern Gulf of Mexico on Wednesday
as the front begins to move SE a cold front, exiting the area to
NW Cuba early on Wednesday. It is possible that the wind speeds
may approach near gale-force in parts of the SE Gulf of Mexico,
as the weak low pressure center moves along the front through
Tuesday. A new surface ridge will build S across the area from
Thursday through Friday night.
