GMZ500-GMZ501-070000- 507 AM CST Tue Jan 6 2026 .SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM... Light onshore winds of around 10 knots and seas of 2 feet or less will be in place through Wednesday night. Conditions also look favorable for fog to develop in the nearshore waters, sounds, and lakes each night through at least Wednesday night. On Thursday, an approaching low pressure system will help to increase winds to 10 to 15 knots. By Friday, these onshore winds should increase further to 15 to 20 knots as the low strengthens. Seas will respond by increasing to 3 to 5 feet in the open Gulf waters. The low will push a cold front through the waters on Saturday, and winds will shift to the northwest. These winds will increase to small craft advisory range by Saturday night as a cold and dry airmass moves in. $$ GMZ530-070000- Lake Pontchartrain and Lake Maurepas- 507 AM CST Tue Jan 6 2026 .TODAY...Southwest winds 5 to 10 knots.
