GMZ500-GMZ501-061300- 701 PM CDT Sun Oct 5 2025 .SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM... Low pressure over the central Gulf and a high pressure system over the eastern seaboard will keep a persistent easterly flow of 15 to 25 knots in place across all of the waters today. These winds will also have a pretty long fetch across the eastern Gulf waters, and this will support higher seas of up to 10 feet in the open Gulf waters due to a combination of wind waves and swell. Small craft advisories are in effect through the afternoon hours due to these hazardous conditions. The high will start to become more dominant over the waters on Monday and Tuesday, and this will allow the easterly winds to relax a bit to between 10 and 15 knots. Seas will also decrease to 2 to 4 feet as the winds relax. This brief respite in rougher conditions will end on Wednesday as another low in the Gulf develops and gradually pushes to the west. Easterly 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. $$ GMZ530-061300- Lake Pontchartrain and Lake Maurepas- 701 PM CDT Sun Oct 5 2025 .TONIGHT...Southeast winds 10 to 15 knots with gusts up to 20 knots.
