GMZ500-GMZ501-060615- 1241 PM CDT Sat Jul 5 2025 .SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM... Marine conditions will be benign through the period outside of any localized impacts from convection. Light offshore flow will persist through the remainder of today, but will become more erratic tonight and then shift to a more onshore direction through the work week. Expect convective coverage to increase through the work week as moisture and instability increase across the region. This convection should follow a typical diurnal pattern, with a daily maximum across the coastal waters during the late night and morning hours, and minimum during the afternoon and evening hours. $$ GMZ530-060615- Lake Pontchartrain and Lake Maurepas- 1241 PM CDT Sat Jul 5 2025 .THIS AFTERNOON...Southwest winds around 5 knots, becoming southeast around 5 knots late.
