This is the dramatic moment a huge shelf cloud inched over a crowded beach during the height of summer.

Tourist Chris McPherson, 33, was enjoying his day at the beach in Barcelona yesterday, July 17, when the massive cloud shadowed the sky black.
In the video, taken by Chris, some of the beachgoers are seen getting ready to make a speedy exit, whilst others stayed lying down, seemingly unconcerned.
Chris, from Melbourne, Australia, said: “My reaction to the scene was that I absolutely loved it!”
