GMZ500-GMZ501-181100- 537 PM CDT Fri Jul 17 2026 .SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM... Surface high pressure centered near and just southeast of the Mississippi River mouth will maintain a generally west to northwest wind regime through the weekend. Winds will commonly be 5 to 10 kt over the tidal lakes and sounds, with 10 to 15 kt winds over the open Gulf waters. The northwest to north flow will be strongest during the overnight and morning hours before winds diminish during the afternoons. Seas should generally remain between 1 and 3 feet, although brief 2 to 4 foot seas will be possible over the eastern open Gulf waters Saturday. Thunderstorm coverage will remain very limited through Saturday. Isolated storms may reach the eastern waters Saturday night into Sunday as the eastern-Gulf upper low edges closer, but most of the marine area should remain dry. Toward the middle of next week, the northern-Gulf surface high should weaken while the western extension of the Bermuda ridge becomes more influential. This should gradually relax the northwest gradient and produce lighter, more variable winds, eventually favoring a weak south or southwest component. The timing of that transition remains somewhat uncertain. Rain chances may also increase modestly over the eastern waters as deeper moisture returns, although widespread marine convection is not presently expected. $$ GMZ529-181100- Lake Maurepas- 537 PM CDT Fri Jul 17 2026 .TONIGHT...West winds around 5 knots.
