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

Winds are gradually turning more south-southwesterly with the
Bermuda ridge centered east of the area and building west across the
Gulf. Wind speeds should be light at 10 knots or less as the
pressure gradient is quite weak. A smaller scale ridge of high
pressure will develop more centered over the north-central Gulf next
week. This will cause winds to become even lighter and variable at
times. With those light winds, waves/seas will generally remain in
the 2 feet or less range. Additionally, thunderstorm activity will
develop each day, peaking in the early to mid-morning hours, and
these storms will produce higher wind gusts, waterspouts, and
lightning concerns.
