Apocalyptic Wave like Clouds appeared over Britain

Looking up at the sky recently in the United Kingdom may have think it was the end of days. The cloud above her skies looked like something from the apocalypse.

But there was no need to be afraid, because it was just a unique formation known as Undulatus asperatus. They happen when wind makes contact with the base of low-lying clouds and although they look dark and gloomy, they usually dissipate without a storm following.
