.SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM...

A low pressure system will pass well north of the region Friday and
Friday night. This will try to push a cold front into the area but
the front will likely stall along or north of the coast. Scattered
showers and a low threat of thunderstorm will accompany this
weakening front on Friday and Friday evening. Winds will calm over
the weekend to less than 10 knots as a high pressure system over the
eastern Gulf becomes more dominant over the waters. However, another
system will once again push winds and seas higher on Monday and
Tuesday. Southerly flow should increase back into the 15 to 20 knot
range over this period. Another round of showers and a few
thunderstorms will also develop over the waters as this next storm
system moves through.
