Marine Weather HF Voice Broadcast for the Gulf of America

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...The northern extension of a tropical wave is over
the Yucatan Peninsula with scattered moderate convection in the
area. This activity will follow the wave as it moves west
through the Bay of Campeche tonight. Some tropical development
is possible in the SW Gulf while the system moves WNW or NW, and
there is a low chance of tropical formation over the next
7 days. Otherwise, gentle winds and slight seas are expected
through the basin as weak high pressure dominates.
