Weak to moderate onshore winds will prevail through Tuesday 
night. Chances for showers and thunderstorms will gradually 
increase through mid week. Deep moisture along with an approaching
weak cold front will result in scattered showers and 
thunderstorms Wednesday and Thursday. Weak to moderate east to 
northeast flow is expected as the frontal boundary moves closer to
the region. Winds will return out of the southeast on Friday. 
Sufficient lingering moisture will maintain rain chances through 
the weekend.

.SYNOPSIS...Generally light to moderate seas can be expected
through much of this forecast period. High pressure will continue
to build across the Gulf of Mexico, which should modestly increase
pressure gradient. Cannot rule out winds reaching cautionary
thresholds from time to time at least through midweek. A cold
frontal boundary will be dropping southward into central Texas by
Thursday. Mariners should expect a gradual increase in shower and
thunderstorm chances as well as locally higher winds and seas in
the heaviest convection.
