.SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM...
Winds are expected to remain near or below 10 knots this weekend, 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 Monday afternoon. 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. After a frontal passage late
Wednesday, winds will increase out of the north to around 15 to
20 knots.
