GMZ500-GMZ501-301800- 1226 AM CDT Sat Aug 30 2025 .SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM... The main marine concern during the next few days of the forecast period will be the threat for thunderstorms that could produce locally higher winds and seas. Gusty outflow winds upwards of gale force are the main threat with any stronger thunderstorms. This pattern continues into early next week as a cold front gradually pushes into the coastal waters. The current wind forecast indicates generally offshore flow by late Sunday afternoon for most or all of the waters as the front pushes in from the northeast. $$ GMZ530-301800- Lake Pontchartrain and Lake Maurepas- 1226 AM CDT Sat Aug 30 2025 .REST OF TONIGHT...South winds around 5 knots, becoming north late.
