Flows in the Lower River Itchen remain high. In the last 3 days, 30mm of rain has been recorded at Portswood. This is over a third of the monthly rainfall for January. The next high tide at Southampton is Wednesday night (29/01/2025) at 23:15, and is forecast at 4.54 metres Chart Datum (1.80 mAOD). The Thursday morning high tide (30/01/2025) is at 11:15 and is forecast at 4.72 metres Chart Datum (1.98 mAOD). Heavy rain is possible Wednesday evening (29/01/2025) with potentially 20mm affecting southern Hampshire. If heavy rain affects the catchment, river levels will rise again and may flood the access road and the car park near to the White Swan Pub at Mansbridge over high tide. We continue to monitor the river and weather forecast. We recommend closing defence gates around the pub at least an hour before high tide. This Flood Alert will be updated by 12:00 on 30/01/2025.
