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...Broad low pressure has formed over the Yucatan
Peninsula, inducing scattered moderate convection over nearby
waters. This low is forecast to move WNW across the SW Gulf
through Fri, through an environment marginally favorable for
further development. There is a low chance of tropical formation
over the next 48 hours, before the system moves inland over NE
Mexico by late Fri. Otherwise, gentle winds and slight seas are
expected through the basin as weak high pressure dominates.
