GMZ500-GMZ501-291300- 701 PM CDT Thu Aug 28 2025 .SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM... The main marine concern during at least the first half of the forecast period will be the increasing threat for thunderstorms that could produce locally higher winds and seas. Maybe not much today, but more certainly Friday into Saturday. Forecast confidence is a bit lower by late in the weekend, with an approaching cold front. The current wind forecast would indicate generally offshore flow by late Sunday afternoon for most or all of the waters. If the front makes it well into the Gulf early next week, that may justify Small Craft Exercise Caution headlines by Monday or Tuesday. $$ GMZ530-291300- Lake Pontchartrain and Lake Maurepas- 701 PM CDT Thu Aug 28 2025 .TONIGHT...South winds around 5 knots.
