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

Winds are expected to hold to a more southerly to southwesterly, or
even westerly component over the next few days as the center of the
surface high pressure over the western Atlantic moves a bit to the
southeast. Wind speeds will generally remain less than 15 knots,
with the more general concern daily/nightly rounds of showers and
thunderstorms, producing locally higher winds and seas. Most frequent
timing will be late night and morning hours over the open waters,
and afternoon and early evening over the lakes and sounds.
