Flooding is expected over the high tides, from Wednesday morning 11th March to the morning tide on Thursday 12th.
High water at Padstow on Weds is at 06:21 and 18:46 and Thurs at 07:03. Times of high water will vary along the coast. Conditions apply two hours either side of high tide, with property flooding expected over the peak of the tide.
Force 6 to 7 west-south-west winds and offshore wave heights are increasing to over 5m on Thursday.
These are forecast to cause wave overtopping and sea spray along the coast including seafront car parks. Expect tides to be up to 500mm higher than predicted. Locations particularly at risk include Port Quinn, Port Isaac, Port Gaverne, Flexbury, Boscastle and Crooklets Beach.
Take care near coastal paths and promenades. Do not drive through flood water or waves.
