GMZ500-GMZ501-051100- 437 PM CST Thu Dec 4 2025 .SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM... Winds have stayed elevated east of the Mississippi River as a developing surface low moves across the coastal waters. This will have multiple impacts with Small Craft Advisory conditions expected Thursday into Friday. With the wind direction being primarily out of the east, minor coastal flooding is expected mainly for St. Bernard, eastern Orleans, southeastern St. Tammany parishes, as well as coastal Hancock and Harrison counties. Winds will relax and return to offshore late Friday and then more variable on Saturday with the passage of another weak sfc low. A frontal passage on Sunday night will bring another push of strong offshore winds on Monday which could prompt small craft headlines for much of the coastal waters. $$ GMZ530-051100- Lake Pontchartrain and Lake Maurepas- 437 PM CST Thu Dec 4 2025 ...SMALL CRAFT ADVISORY IN EFFECT THROUGH LATE TONIGHT... .TONIGHT...Northeast winds around 15 knots with gusts up to 20 knots, becoming north late this evening and overnight.
