We have only been collating detailed flood messages since May 2017.
Each Flood Alert may have multiple updates. The messages listed below may therefore be greater than the number of alerts detailed in the Flood Alert table above.
Flood Alert issued on 2 Feb 2021 11:56
Tide heights will decrease by 10 cm each high water for the next two days. Strong South Westerly Force 5 to 6 winds will continue throughout Tuesday (02/02/2021), before easing on Wednesday (03/02/2021). Wave heights are still large and will increase on Tuesday evening, before decreasing on Thursday (04/02/2021). Shingle will still be moved and wave spray will affect sea front areas, particularly over the high tide periods (which are 14:30 on 02/02/2021, 03:00 and 15:15 on 03/02/2021). Small amounts of water may still potentially affect nearby fields, roads and beach top properties. However, the waves are not expected to run up the beach quite as much as they did on Monday. Please take care if visiting the sea front between Tuesday and Thursday. Large waves are very powerful and can contain hidden dangers such as flying debris. We will update this message by 12:00 on 03/02/2021.
Flood Alert issued on 1 Feb 2021 18:58
High energy waves experienced Monday could persist into Tuesday and over the next high tide. Tuesday's early morning tide at 02:30 on 02/02/2021 is higher than normal due to unsettled weather with strong South Westerly Force 5 winds. The weather increases tide table values by 0.18 m. The total forecast tide is 4.97 metres Chart Datum (2.23 mAOD) at Chichester Harbour. For two hours either side of high tide, the high energy waves could run up the beach and affect beach top properties at the end of West Sands Lane and Medmerry. Tide levels should be a little lower Tuesday afternoon, with smaller waves and less impacts too. We continue to monitor the forecast. Large waves and moving shingle beaches can be dangerous. Please take care if near the seafront this evening. We will update this message by 14:00 on 02/02/2021
