A massive wave almost carried a man and a child out to sea after it crashed down on them as they stood on the seafront.
The man, wearing an orange jacket, was walking along the shoreline giving the child a piggyback in Freshwater on the Isle of Wight this weekend.
The clip shows the man standing on some pavement near to the water's edge.
In seconds, he realises that there is a large wave heading straight for him.
He runs to the pavement but the water engulfs him and the child as screams can be heard in the background.
The man is knocked to the floor and the child falls off his back.
He reaches out and grabs the youngster as the waves threaten to pull them both out to sea.
The man then stands up as onlookers rush to help him.
Guy Addington from the RNLI told the BBC: 'People need to be aware that during strong winds parts of our coastline can be treacherous, with a higher risk of large waves sweeping people off their feet and resulting in them being dragged into the sea.'
The UK was battered by severe storms this weekend leaving parts of the country underwater.
Rain was so heavy in Pontardawe and Swansea, Wales, that cars were immersed in water up to their windscreens as they drove down streets.
More floods are set to hit this week as rain lashes down on most of the country.
The Met Office has issued a yellow warning for today while the Environment Agency put in place 44 flood warnings - where residents are advised to be prepared as flooding is expected.
However, the weather is set to pick up tomorrow with a mix of partly cloudy skies, sunny spells and showers for most areas on Tuesday.
Southern parts of the country are likely to see the best of any sunshine while eastern areas of the UK are more likely to have some mostly light showers.
However, this relief is only temporary as cloud is set to thicken on Wednesday with outbreaks of rain pushing into western areas, turning heavy.
