GMZ500-GMZ501-071100- 506 PM CDT Mon Oct 6 2025 .SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM... High pressure will start to become more dominant over the waters early this week, allowing easterly to southeasterly winds to relax a bit to between 10 and 15 knots. Seas will also decrease to 2 to 4 feet as the fetch relaxes. This brief respite in rougher conditions will end on Wednesday as another low in the Gulf develops and gradually pushes to the west. Northeasterly winds will increase back to near advisory levels in the offshore waters and seas will increase to 4 to 6 feet from Wednesday through Friday and perhaps beyond. As for tidal lakes and nearshore waters, cautionary headlines are likely, but cannot rule out the need for Small Craft Advisories even in a general weaker offshore flow regime. $$ GMZ530-071100- Lake Pontchartrain and Lake Maurepas- 506 PM CDT Mon Oct 6 2025 .TONIGHT...Southeast winds 5 to 10 knots.
