.SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM...
A series of fast moving low pressure systems will pass north of the
waters over the next several days. Weak trailing cold fronts will
slide toward the waters over this period and stall out along the
coast. The first of these systems will bring stronger southerly
winds of 15 to 20 knots and slightly higher seas to the waters
Thursday night into Friday. Scattered showers and a low threat of
thunderstorm will accompany this weakening front on Friday. 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.
