GMZ500-GMZ501-301800- 1127 PM CST Sat Nov 29 2025 .SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM... A front will approach coastal/nearshore waters today and come to a slowdown and eventually stall introducing intermittent light showers, with better chances along the immediate coast. Winds will shift out of the north behind the front with winds picking up in the 10-15kt range later this afternoon/evening to 15-20kts overnight Sunday into Monday, mainly across the Tidal Lakes, nearshore sounds/gulf waters and southwest into waters west of the mouth of the MS. 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 thru early Tuesday, leading to the possibility of the Small Craft Advisory to be extended in time, though confidence for now remains low. The main impacts will be periods of heavy rain, and some strong to potentially severe thunderstorms producing winds >34 knots, locally enhanced waves/seas and waterspouts. Once the low approaches land over coastal MS/AL, a front will sweep across the area allowing winds to shift out of the NW and waves/seas increase steadily to around 5-7ft for offshore Gulf zones thru Tuesday, where additional headlines could likely be required. High pressure settles in mid-week calming down winds and waves/seas, however, confidence is increasing that we`ll see another system approach Gulf waters later in the week with another increase in winds and shower/storm activity.
