Flood Warning issued on 12 Feb 2020 15:41
South Cornwall Coast
Flooding is expected over the high tide on Thursday morning 13th February. High water at Truro is 08:14. Times of high water will vary along the coast. Conditions may apply two hours either side of the high tide, with property flooding expected over the peak of the tide. Water levels are forecast to be higher than recent high tides associated with Storm Ciara, therefore increased flood impacts are likely. Force 7 west south westerly winds and offshore waves of 4 to 5m are forecast to cause wave overtopping of sea defences and sea spray in exposed coastal locations. Expect tides to be around 0.3m higher than predicted due to weather conditions. Locations particularly at risk include Pentewan, Gorran Haven, Flushing, Penryn and the A39 at Perranarworthal. Take care near coastal paths and promenades. Keep up to date with local radio. We are monitoring the situation and will update this information on Thursday morning, or if the situation changes.
