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 ridge extending from the western Atlantic into the
Gulf will support moderate to fresh winds across the central and
western Gulf through Wed night. The ridge will shift eastward,
allowing for gentle to moderate winds and slight to moderate
seas across the entire basin Thu as a weak frontal boundary
stalls and dissipates along the Texas coast. Looking ahead,
southeast to south winds are expected to increase over the
western Gulf by late Fri as low pressure moves into the Central
Plains. A strong cold front associated with this low pressure
may reach the Texas coast late Sat night or early Sun before it
quickly moves to the eastern Gulf late Sun. Gale-force winds are
possible behind the front over the western Gulf from early Sun
through Mon night, with strong to near gale-force winds
elsewhere across the area in the wake of the front. Seas are
expected to quickly build behind the front as well.
