This is the scary moment a driver and his wife got caught out by a sudden tidal surge during Storm Dennis.

Video shows the driver parked on Benone beach in Northern Ireland, surrounded by other vehicles, when a storm surge comes on shore and motorists frantically try to escape before their cars are engulfed by rushing water.

"We’re caught out," says driver Martin as he and his wife see another car get surrounded by water.

"How we gonna ... ?" asks his wife.

"Sit your ground," says Martin.

"Do what? MARTIN!" says his wife, now panicked by the onrushing seawater.

"Wait for it to go out again. Hope we don’t sink in. There’s no point fighting in," Martin says,

"Did you see how quickly that came in there? It’s going back out," says Martin's wife, relieved.

"If we get stuck in this sand, we’re screwed!" Martin adds, before the danger passes.

"That’s scary! I can’t believe that happened," says Martin's wife as the car is able to be driven away.

A storm surge suddenly comes on shore at Benone beach, N. Ireland during storm dennis. Drivers frantically try to escape before being engulfed by the rushing high water. I was one of those drivers, my dash cam captured the moment, due to the cars all moving at once it was unsafe to suddenly reverse so I had to let it over take us and wait for the water to recede so we could get back again, we got stuck but we were helped out my passersby who pushed us out, Everyone safe and fine, but it made for a dramatic moment, excuse some of the colourful words, my wife was a little shook up.
