294 FZUS54 KLIX 302237 CWFLIX Coastal Waters Forecast National Weather Service New Orleans LA 437 PM CST Sun Nov 30 2025 Pascagoula to Atchafalaya River out to 60 NM Seas are provided as a range of the average height of the highest 1/3 of the waves...along with the occasional height of the average highest 10 percent of the waves. GMZ500-GMZ501-011100- 437 PM CST Sun Nov 30 2025 .SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM... Winds will shift out of the north behind a cold front today with winds increasing to 10 to 15 knots later this afternoon and evening, then to 15 to 25 knots overnight into Monday, mainly across the Tidal Lakes and sounds, and much of the open gulf waters. A Small Craft Advisory is now in effect for these areas through noon Monday. It is highly cautioned that the eventual strength of the low will determine the potential for stronger winds to persist beyond early Tuesday, leading to the possibility of the Small Craft Advisory to be extended in time, though confidence for now remains low. High pressure settles in mid-week calming down winds and waves/seas briefly, however, confidence is increasing that we`ll see another system approach Gulf waters later in the week with another increase in winds and seas. $$ GMZ530-011100- Lake Pontchartrain and Lake Maurepas- 437 PM CST Sun Nov 30 2025 ...SMALL CRAFT EXERCISE CAUTION IN EFFECT UNTIL 6 PM CST THIS EVENING... ...SMALL CRAFT ADVISORY IN EFFECT THROUGH MONDAY MORNING... .TONIGHT...Northeast winds 15 to 20 knots with gusts up to 30 knots.
