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...A broad area of low pressure, AL93, extends from
Mobile Bay southward to near 28N89W. This system is forecast to
continue moving westward across northern portions of the Gulf
and reach SE Louisiana late today. If this system moves far
enough offshore, environmental conditions over the Gulf appear
generally favorable for additional development, and a tropical
depression could form over the next day or two before the system
moves fully inland by Fri. Regardless of development, heavy
showers and thunderstorms are expected over the north-central
Gulf through Fri, with erratic gusty winds and rough seas
possible near convection. Atlantic high pressure will shift
westward into the NE Gulf over the weekend.
