.SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM...
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. After the frontal passage late
Wednesday , winds will increase out of the north up around 15-20kts
once again. There is a chance of dense fog over some areas Saturday
morning and subsequently a dense fog advisory was issued for the
lakes, sounds, and eastern near waters.
