.SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM...
High pressure anchored to the east offshore the mid-Atlantic states
will continue to provide onshore SE flow this weekend into next
week. Sustained winds of 15 to 20 knots could raise small craft
exercise caution headlines for waters near and south of Terrebonne
Bay on Sunday and Monday, when the pressure gradient is at its
tightest. Moisture steadily increasing will begin to provide a few
scattered shower chances mainly next week, with best chances mainly
late-week as a front approaches the northern Gulf coast. Waves/seas
will steadily increase early next week given ongoing SE fetch
reaching 3-5ft for outer Gulf waters (primarily west of the MS
delta) to 2-3ft for nearshore waters, but winds back down some
mid/late week reducing wave/seas.
