.SYNOPSIS...Favorable marine conditions are expected through the
weekend as high pressure dominates the northern and western Gulf
of Mexico. Winds and seas slowly increase next week as an area of
low pressure possibly develops over the Bay of Campeche
enhancing the pressure gradient across the Southwest Gulf.
Mariners need to monitor the forecast daily for increasing winds,
seas and the chance of heavy showers and thunderstorms most of
next week.
