A storm surge combined with gale force winds and high-tides have prompted a flood alert to be issued for the North Cornwall coastline this evening.
The surge is expected to measure nearly a metre above the predicted high tide levels, which are due to be reached between 5.30pm and 6pm along the stretch of coast from Land's End to Hartland Point.
They coincide with the arrival of this evening's predicted storm, which could see winds gusting up to 70mph, combined with heavy rain.
An Environment Agency statement issued this lunchtime said: "Flooding is possible to low lying and exposed coastal frontages for Wednesday evening’s high tide, which can cause hazardous conditions in these locations.
"Tidal levels are predicted to be higher due to a surge combined with large waves. The surge is forecast to be 0.85m above published (tide book) levels.
"The wind direction is Westerly, wind strength is Force 9 and large waves are expected. Westerly facing exposed coastal areas are most likely to be affected.
"The local time of high water on 18 Dec 2013 is 17:41 at St Ives and 17:58 at Padstow.
"The times of high tide will vary along the coast. Conditions will usually apply 2-4 hours either side of high tide.
"These conditions only apply to Wednesday evenings tide as the surge is forecast to reduce significantly overnight.
