River Itchen
Friday afternoon's tide at 13:18 on 21/08/2020 and 15:33 on 21/08/2020 is higher than normal due to unsettled weather with strong South Westerly Force 7 winds. The weather increases tide table values by 0.34 m (surge). The forecast tide is 5.14 metres Chart Datum (2.40 mAOD) at Southampton. For 1 hour either side of high water, levels in the lower River Itchen will increase as the incoming tide will prevent water from flowing out to sea. Footpath flooding will affect parts of Riverside Park, and it may flood into the access road next to the White Swan pub for a short period of time. Flood depths will be very shallow. The tide will not flood property or the A27. After this tide‚ the weather becomes more settled and no further impacts are expected. We continue to monitor the forecast. As a very precautionary measure, we recommend that tidal defence gates at the pub are closed. We will remove this message by 17:00 on 21/08/2020.

Flood Alert issued on 20 Feb 2020 23:23
River Itchen
In the Lower River Itchen, flows remain high. The tide at Southampton has come in higher than forecast this evening (Thursday 20/02/2020) and is currently preventing the river from draining to the sea. Over the next hour, while the tide level remains high, it is possible that some water may come out of bank, affecting the car park at the White Swan Pub. Forecast tide levels tomorrow are unlikely to cause impacts. We recommend that defence gates at the pub are closed tonight. Our sea door at Woodmill remains open in order to help lower water levels in the river. This Flood Alert will be updated by 10:00 on Friday 21/02/2020


Flood Alert issued on 17 Feb 2020 07:40
River Itchen
Water levels in the Lower River Itchen remain very high following heavy rainfall over the last 48 hours. Today, whilst flows in the river remain so high, even though tide levels are low, it may still cause a slight increase in water level around the time of next high water, expected at Southampton at 18:08 and 19:27 (17/02/2020). Over the next 5 days, small amounts of rain are expected each day, but the general trend is that water levels in the river should continue to fall. Today, the rate of any fall is likely to be slow. Our sea door at Woodmill is open to help lower water levels in the river. Today, we recommend that tidal defence gates at the pub remain closed. This Flood Alert will be updated or removed by 12:00 on Tuesday 18/02/2020.


Flood Alert issued on 16 Feb 2020 12:57
River Itchen
High flows are affecting the Lower River Itchen. 14mm of rain has been recorded at Portswood in the last 24hours. This is a smaller amount of rain than was forecast, but still significant as the catchment is very wet. For 1.5 hours either side of high tide this afternoon (16/02/20) which is forecast at Southampton at 17:00 and 18:13, water will be prevented from flowing from the river to the sea. This may cause the river to flood the access road and affect the car park near to the White Swan Pub at Mansbridge. Rainfall continues to effect Hampshire until later this afternoon. The forecast into the week ahead is unsettled but with smaller rainfall totals. We continue to monitor the river. We recommend closing the defence gates around the pub. In Riverside Park, avoid flooded areas, the edge of the river bank might be closer than you think. This Flood Alert will be updated at 16:00 on 17/02/20, or sooner if required.


Flood Alert issued on 14 Feb 2020 16:13
River Itchen
In the Lower River Itchen, flows remain high. Between Friday (14/02/2020) and Monday (17/02/2020), very heavy rainfall could affect Hampshire, with 30 to 60mm forecast. This is a large volume of rain and could increase river flows significantly. On Saturday (15/02/2020) at 16:00 and 17:16 the tide level at Southampton is slightly elevated. For 1.5 hours either side of high water, it could cause the river to flood the car park at the White Swan Pub. From Saturday evening onwards, tide levels will reduce and should have less of an impact at each high water. However, this weekend, we recommend that defence gates remain closed around the pub. We continue to monitor the forecast and have opened our sea door at Woodmill to help lower water levels in the river. Please take appropriate action to protect property. This Flood Alert will be updated on Sunday 16/02/2020 by 12:00.

River Itchen
Thursday afternoon's tide at 13:47 and 15:39 on 13/02/2020 is higher than normal due to unsettled weather with strong Westerly Force 5 winds. The weather increases tide table values by 0.44 m. The total forecast tide is 5.04 metres Chart Datum (2.30 mAOD) at Southampton. For 1.5 hours either side of high water, levels in the lower River Itchen will increase as the incoming tide prevents water from flowing out to sea. Footpath flooding will affect parts of Riverside Park. The pub car park at Mansbridge, could see minor impact flooding for a short period of time. The tide will not flood the A27. After this tide, conditions improve until the weekend, when Storm Dennis may bring very heavy rainfall. Further messages may be required. To help reduce flood risk, our sea door at Woodmill is partially open. Please consider installing the temporary flood barrier to the access road at Mansbridge and closing defence gates at the pub. We will remove this message by 17:00 on 13/02/2020


Flood Alert issued on 16 Jan 2020 11:43
River Itchen
Water levels in the lower River Itchen remain high, but have fallen since the heavy rainfall and high tides yesterday. Tide levels are now reducing, and over the next few days should have much less of an impact on the river. Today (16/01/2020), the forecast rainfall totals have increased, with up to 30mm expected. This is a large volume of rain and should that affect the river, then levels will rise quickly. Even though the tide is not overly high, some impacts may occur for 1.5 hours either side of high water for the tide expected at the following times: 03:49, 05:27, 15:34 and 18:19 on Friday 17/01/2020. Once this rainfall has passed, the situation should improve. Our sea door is open at Woodmill to help reduce levels in the river. As a precautionary measure, we recommend that tidal defence gates at the pub remain closed. This message will be updated by 12:00 on 17/01/2020.

Water levels in the Lower River Itchen remain high. Water levels have fallen following last night’s high tide, but will increase again during this morning’s high tide (11:23), and may increase again during tonight’s high tide (23:53).

Flood Alert issued on 26 Dec 2019 21:53
River Itchen
High flows are affecting Lower River Itchen at Mansbridge. In the last 24 hours 6mm of rain has fallen. This is in addition to prolonged rainfall experienced recently. High tide is forecast tonight (26/12/19) 23:10, and tomorrow (27/12/19) 11:23. For 30minutes either side of high water, incoming tide prevents the river from flowing to sea. This may cause the river to come out of bank, affecting access road and car parking areas near White Swan Pub and car garage at Mansbridge. Impacts should be minor, no property flooding is expected. Footpath flooding may affect Riverside Park. Due to the prolonged rainfall which has already fallen, river flows will remain high over the next few days. Minor impacts could occur at high tides. We continue to monitor levels. For an hour either side of high tide, we recommend closing defence gates around the pub. Consider deploying temporary flood barrier. In Riverside Park, avoid flooded areas. Flood Alert will be updated by 12:00 on 27/12/19.


Flood Alert issued on 23 Dec 2019 10:38
River Itchen
Water levels in the Lower River Itchen remain high, although they have decreased slightly over the last 24 hours. Today (23/12/2019), the weather remains fairly dry with only the odd light shower expected. Water levels should continue to lower. Overnight and into tomorrow (24/12/2019), further rain is forecast. If this rain affects the river, then it will cause it to rise. Tomorrow mornings tide at Southampton at 09:19 and 10:37 on 24/12/2019 is also high enough to cause a moderate increase in river level. Christmas Day will remain dry, before another band of rain arrives on Boxing Day (26/12/2019). High tides on Boxing day are also high enough to increase levels. Woodmill sluice and sea door are fully open to help reduce water levels. Tomorrow morning, we recommend that defence gates at the pub are closed over high water. This Flood Alert will be updated by 12:00 on 24/12/2019.


Flood Alert issued on 22 Dec 2019 11:29
River Itchen
Water levels in the Lower River Itchen remain very high following a small amount of additional rainfall yesterday and a higher tide this morning. Flooding of Riverside Park and high levels at Mansbridge will continue over the next few days. Today and tomorrow (Monday 23/12/2019) the weather improves, with only very small amounts of rain expected (2-3mm). This will allow levels in the river to continue to fall and to recover a little. However, they will increase for 1.5 hours at each high tide, especially over the next 24 hours. This evening, high tide at Southampton is at 20:08 and 21:15 and tomorrow morning (Monday 23/12/2019) it is expected at 08:40 and 09:50. At Woodmill, our sluices and sea door are open in order to allow as much water as possible to drain from the river in between high tide. For the next 2 high tides we recommend that the defence gates around the pub remain closed. This message will be updated by 12:00 on 23/12/2019.


Flood Alert issued on 21 Dec 2019 09:52
River Itchen
Flows in Lower River Itchen remain high, although they have decreased slightly over the last 24 hours. Today (Saturday 21/12/2019) further rain is forecast, with up to 25mm expected. If this rain affects the Itchen, then flows will increase throughout the day and overnight. Sunday mornings, high tide at Southampton, forecast at 07:30 and 08:50 on 22/12/2019 is high at 5 mCD. For 1.5 hours over high tide, levels in the river will increase. If the river is also rising as a result of any heavy rain which has fallen today, this could cause flooding to the pub and car park. From tomorrow (Sunday 22/12/2019), the rainfall forecast improves. This will give the river a chance to recover. Our operational staff are reducing levels in the river by opening our sea door at Woodmill in between high tides. We recommend that defence gates at the pub remain closed. This Flood Alert will be updated by 11:00 on 22/12/2019.

Flood Alert issued on 19 Dec 2019 15:21
River Itchen
High flows are affecting the Lower River Itchen. 16mm of rain has been recorded at Portswood in the last 24 hours. This is a large volume in a short amount of time in addition to the prolonged wet weather we have had in the last few months. Around high tide (16:20 19/12/2019), water will be prevented from flowing from the river to the sea. This will cause the river to affect the access road and car parking areas near to the White Swan Pub and car garage at Mansbridge. Further rainfall is forecast this evening and through the weekend. Minor flood impacts are expected throughout this period. We continue to monitor water levels. We recommend closing the gates around the pub. In Riverside Park, avoid flooded areas, the edge of the river bank might be closer than you think. This Flood Alert will be updated at 11:00 20/12/2019.
