.SYNOPSIS...
Winds and seas will continue to gradually subside tonight as the
pressure gradient between a surface trough, the remnants of
Rafael, and a weak surface high across Louisiana relaxes. The low
will meander north over the coastal waters tonight, merging with
a cold front moving through the region on Wednesday. This will
lead to an increase in showers and thunderstorms over the coastal
waters tonight into Wednesday. Winds will shift northerly  by
Wednesday evening and strengthen on Thursday in the wake of the
front. Winds will diminish and shift more easterly by the end of
the week.
