GMZ500-GMZ501-030615- 1239 PM CDT Wed Jul 2 2025 .SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM... Offshore flow has developed on this afternoon and will continue into the early part of the weekend. Scattered showers and thunderstorms will continue through the evening hours, but a lower threat of thunderstorms is expected from Thursday through Saturday as a drier area of high pressure moves in. The high will shift to the west and a broad area of low pressure will move in from the east for early next week. This will allow winds to shift back to an onshore flow and thunderstorm chances will increase. However, no significant impacts to mariners are expected through the period outside of locally higher winds and waves near any thunderstorms that form. $$ GMZ530-030615- Lake Pontchartrain and Lake Maurepas- 1239 PM CDT Wed Jul 2 2025 .TONIGHT...West winds around 5 knots, becoming northwest late.
