.SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM...
Offshore flow will continue as weak low pressure slowly works
towards the southwestern Gulf. This will continue to produce light
to moderate offshore flow over the next few days. Overall, not
anticipating a lot of impacts through midweek, but a few showers and
thunderstorms may begin to develop over the coastal waters Tuesday
and Wednesday. Winds, seas/waves, and rain chances will begin to
increase late in the week. Headlines will likely be needed and could
be needed as early as Thursday night. With broad high pressure
centered across the northeast and mid Atlantic and wedging southwest
towards the Gulf coast and weak low pressure over the Bay of
Campeche the pressure gradient will tighten and strong easterly
winds could set up across the northern Gulf for multiple days.
