With the coming of summer in Denmark, you'll also experience a few battles between cold and warm masses of air, so expect some summer thunderstorms with heavy rain. Well, I know heavy rain in Denmark is nothing compared to other places, but to Danes 24 mm rain in 6 hours is considered heavy rain. And it seems like these thunderstorms are more frequent and more severe now than just 10 years ago. So the communities has to prepare for it with better drainage and reservoirs for the overflow. This little time lapse video was shot out my window Wednesday when most of the country was hit by a series of thunderstorms.
