GMZ500-GMZ501-191400- 822 PM CDT Sat Jul 18 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 at around 10 knots through the weekend. The northwest to north flow will be strongest during the overnight hours approaching 15 knots before winds diminish during the day. Thunderstorm coverage will remain very limited today but isolated storms may reach the eastern waters tonight through Monday as the eastern-Gulf upper low edges closer, but most of the marine area should remain dry. By mid week, winds remain westerly at around 10 knots and rain chances will also increase modestly in waters east of the Miss River as deeper moisture returns, although widespread marine convection is not presently expected. $$ GMZ529-191400- Lake Maurepas- 822 PM CDT Sat Jul 18 2026 .TONIGHT...West winds 5 to 10 knots.
