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...Strong thunderstorms will continue across W Gulf of
Mexico through Fri and will be capable of producing locally
near- gale force winds and seas to 10 ft. Meanwhile, a strong
ridge stretching from eastern seaboard to the NE Gulf will
continue to dominate the Gulf waters through the remainder of
the week. The pressure gradient between the ridge and deepening
low pressure across the Southern Plains will support fresh to
strong SE winds and high seas across the Gulf region through
Sat. Seas will peak 9 to 11 ft through Fri in the Straits of
Florida and 12 ft in the N central Gulf on Fri.
