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

Overall not a lot of impacts in the forecast for the coastal waters.
A low pressure system will pass well north of the region tomorrow
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.
Southerly winds will increase to around 15 knots with slightly
higher seas tonight and tomorrow. 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 low pressure 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.
