GMZ500-GMZ501-021800- 1126 PM CST Mon Dec 1 2025 .SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM... A broad area of low pressure just south of the coast will continue to lift to the east-northeast into the Florida panhandle and then southern Georgia by late this morning. We are already seeing strong offshore winds on the back side of the surface low with winds gusts from 25 to 30 kts west of the mouth of the river. Winds will respond over the rest of the coastal waters as the surface low continues to move through and lifts out. The strong offshore winds will remain in place through midday slowly weakening throughout the afternoon as high pressure builds over the Lower Mississippi Valley. A small craft advisory is already in effect for all of the coastal waters and will remain so through midday. Winds should relax enough for it today drop off everywhere by mid/late afternoon. High pressure will quickly slide east across the southern US with light onshore flow returning Wednesday morning. The next system will quickly begin to take shape with broad low pressure over the western Gulf by Thursday and moving through the coastal waters Thursday night and early Friday. $$ GMZ530-021800- Lake Pontchartrain and Lake Maurepas- 1126 PM CST Mon Dec 1 2025 ...SMALL CRAFT ADVISORY IN EFFECT THROUGH TUESDAY AFTERNOON... .REST OF TONIGHT...North winds 15 to 20 knots with gusts up to 25 knots, becoming northwest with gusts up to 30 knots late.
