People living on the south coast of England had a shock on Sunday when a 'tornado' swept along the seafront.
The dark swirling funnel was spotted 300m above the sea off Brighton. The stormy cloud lost its strength before it hit nearby cliffs.
It hovered about a mile out to sea and could be seen from Brighton pier.
Eyewitness Peter Machin, who lives in Brighton, said he watched the cloud for 10 to 15 minutes. He said: "I was absolutely gobsmacked."
"It was moving towards Peacehaven and seemed to be getting bigger and bigger as it got closer."

Coastguards put out a warning to ships in the area but there were no reports of any injuries or any ships getting into trouble.
Although most people were calling the cloud a tornado, technically it was known as a 'waterspout' because it didn't actually hit land.
Tornadoes form when a warm wind meets a cold one and this is most likely to happen in the UK during late summer.

I live in Brighton and me and my girlfriend had to run for shelter and it was a shock for both of us. I think this happened because of climate change.
