In the south, it comes from noon to heavy thunderstorms and storms. The big problem is the heavy rain. The thunderstorms are moving very slowly and at the same time have loaded a lot of moisture. This means that it comes to real downpour. It can come down to 100 liters of rain per square meter within a short time, which is significantly more than the rain of a whole month.
There are floods on roads and on small rivers and streams. Even basements can run fast, so you should avoid these danger spots on Wednesday. Although the thunderstorms are limited in space, they can occur anywhere in the south, so be careful from Wednesday noon.
The maximum values increase to 22 to 32 degrees and the heat load due to the humid air is high. Physical exertion in the open air should be reduced to a necessary level.
