Flood Warning issued on 16 Nov 2020 07:24
River Itchen
The Lower River Itchen remains very high following heavy rainfall over the weekend. High tide at Southampton is forecast at 11:09 on 16/11/2020 and 13:21 on 16/11/2020. The tide is still higher than normal, but will be lower than recorded in recent days, forecast at 5.03 m Chart Datum (2.29 mAOD). Given that flows in the river are still very high, for 1 hour either side of high tide, water may still come out of bank, flooding the access road and car parking areas near the White Swan Pub and the car garage at Mansbridge. Impacts should be much less than experienced over the weekend. For the next 4 days, the weather should be dry, and tide levels continue to lower. This will give the river a chance to return to normal and the situation will improve. The sea door at Woodmill remains open, and it is helping to lower levels in the river. We recommend closing the defence gates around the pub. This Flood Warning will be updated by 18:00 on Monday 16/11/2020.

The Lower River Itchen remains very high. In the last 24 hours, half a month’s rain (42mm) has been recorded at Portswood. High tide at Southampton is forecast at 22:46 on 15/11/2020 and 01:00 on 16/11/2020. Tide levels are again higher than normal, forecast at 5.22 m Chart Datum (2.48mAOD). Heavy showers are expected this afternoon between 15:00 and 17:00. Given that flows in the river are still very high, for 2 hours either side of high tide water may still come out of bank, flooding the access road and car parking areas near the White Swan Pub and car garage at Mansbridge. Tomorrow, whilst tide levels remain elevated, they are reducing and the weather is drier. The situation should now generally improve. The sea door at Woodmill remains open and it is helping to lower levels in the river. We recommend closing the defence gates around the pub. This Flood Warning will be updated by 08:00 on Monday 16/11/2020.

River Itchen
Water levels in the Lower River Itchen are very high. In the last 15 hours more than 30mm of rain has been recorded at Portswood. This is a large amount in a short period of time. It is currently high tide at Southampton and the amount of river water that can drain to sea is being restricted. For the next 2 to 3 hours, the river will remain very high until tide levels begin to fall. Some water may be forced up through the floor of the Pub. Flooding could also affect the pub car park and may come close to the car garage. Parts of Riverside Park will also be flooded. Heavy rain and high tides are forecast again tomorrow (Sunday 15/11/2020) and a Flood Alert remains in force for next high tide expected at 10:26 and 12:35. To help lower water levels in the river, we have opened the sea door at Woodmill. Only minor impact flooding should occur at next high tide. Tidal defence gates around the pub should be closed. This Flood Warning will be updated by 11:00 on Sunday 15/11/2020.


Flood Warning issued on 9 Feb 2020 12:32
River Itchen
Monday morning's tide at 11:34 and 13:39 on 10/02/2020 is higher than normal due to Storm Ciara, which brings strong South Westerly Force 7 winds. The weather increases tide table values by 0.58 m. The total forecast tide is 5.38 metres Chart Datum (2.64 mAOD) at Southampton. For 1.5 hours either side of high water, levels in the lower River Itchen will rise as the incoming tide prevents water flowing out to sea. The access road near the pub will flood. Without a barrier installed, it will flood the pub car park and could flood the car garage. Footpath flooding is expected in Riverside Park. Levels will be very high around the Activity Centre. At 23:57 on 10/02/2020 the tide is lower, but minor impacts may still occur. We may issue further advice. We continue to monitor the forecast. At Mansbridge, please consider installing the temporary flood barrier and closing defence gates at the pub 1 hour before high tide. We will update this message by 16:00 on 10/02/2020.
