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

Surface high pressure centered over the central Gulf will maintain a
generally weak pressure gradient through much of the period. A
predominantly westerly flow regime will continue, with a typical
summertime diurnal fluctuation in both direction and speed. Winds
should generally increase during the overnight and early morning
hours to around 10 to 15 knots before relaxing to around 5 to
10 knots during the late morning and afternoon. Nearshore winds may
become more southwesterly during the afternoon as the sea breeze
develops. Seas over the open waters will generally be around 2 to
3 feet during the stronger nighttime flow and closer to 2 feet or
less during the day, with considerably lower wave heights across the
tidal lakes and protected waters. Isolated thunderstorms will remain
possible, particularly during the overnight and early morning hours
over the coastal waters and nearer the coast during the afternoon.
Locally higher winds and seas along with frequent lightning will be
possible near any thunderstorm.
