Flooding expected. Take action now.
Tuesday's early morning tide at 00:15 on 09/04/2024 is higher than normal, due to unsettled weather with strong Southerly Force 7 winds and large waves. The weather increases tide table values by 0.76 m. The total forecast tide is 5.75 metres Chart Datum (3.02 mAOD) at Portsmouth. The tide will be the highest ever recorded. For 1 hour either side of high water, commercial property at Hamilton Road Industrial Estate may flood as the tide could exceed the top of the main slipway. Spray overtopping and shingle debris will affect the A27 Southampton Road at Paulsgrove. After this tide the weather becomes more settled but minor impacts could continue until Thursday (11/04/2024). We continue to monitor the forecast. If you have it, please install flood protection 1 hour before high tide. We will remove this message by 16:00 on 09/04/2024.
