People living along the south coast of Cornwall are being warned to “act now” following a red flood warning.

The Environment Agency has said flooding is expected from Land’s End to Lizard Point, across Mounts Bay, the tidal areas of Helford and the River Fal, and up to Rame Head.

Storm Ciaran is set to bring strong winds, significant waves and a tidal surge leading to an increased risk of coastal flooding.

Key tides of concern are this evening (Wednesday) at 6.42pm and tomorrow (Thursday) morning, 7am. The times given are for Newlyn and will vary along the coast.

The EA said: “Possibly, significant wind and wave overtopping could result in dangerous conditions on the coastline with the potential for fast flowing water.

“Take care near the coastline and do not drive through waves or flood water.  Please continue to monitor your local weather conditions and take care in the areas of concern.”

It is actively monitoring the situation.
