Atlantic swell sparks surf concerns for Devon and Cornwall

Mr Martin, who was taking photographs of stormy seas, was last seen by his father leaving his home and walking towards a coastal path on Thursday lunchtime.Costs 'will rise'
Dave Owens, the assistant head of service for the environment at Cornwall Council, said: "At the moment with the damage we know that has happened to date we're up to about £1.5m. That is only going to go higher.
"That doesn't include anything on the coast path yet. We will probably get collapses as a consequence of this weather, for probably around 12 months."
The harbourmaster at Newquay said so much sand had been lost from the harbour it had exposed a boat wreck never seen before.
Graham Alecock-Smith said: "We've got some guys who have been in town for 60 years but nobody recalls seeing it before.

The boat will be removed on Tuesday for health and safety reasons, Mr Alecock-Smith confirmed.

Sgt Butler said "another 30 seconds" and the man could have been washed out to sea.

The Maritime and Coastguard Agency and Devon and Cornwall Police said while they could not stop people going into the water, they urged them not to put themselves or others in danger.

"If they're in any doubt at all, then I'd say, 'please don't do it'."
Last October, Devon surfer Andrew Cotton, from Braunton, hit the headlines when he surfed a 100ft (30m) wave off Nazare beach in Portugal.
Mr Cotton said he intended to ride the surf off Ireland, but will do so only if he believed it was safe.
"My advice would be not to go out alone and to be realistic about your ability," he told BBC News.
"Know your limits. The sea is so powerful and demands the utmost respect."
"Knowing when to call it quits can make the difference between surfing again tomorrow or never surfing again," he added.

"If you're not really experienced, my advice is simple - stay out the water," the 51-year-old from Hayle said.
