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

Generally benign marine conditions are forecast through midweek with
winds less than 10 kts and waves/seas 2-3 ft or lower. As the
pressure gradient tightens Thursday ahead of a cold front, winds and
seas will respond accordingly, but should remain below headline
criteria through the end of the work week. Biggest concern through
the work week will be fog potential. Greatest threat currently
appears to be Wednesday night into Thursday morning.
