But the heat has its downsides: The risk of forest fires is high. In large parts of the country there is already a considerable danger (level 3), locally even the highest warning level 5 applies. The federal government is also calling for caution: The level 3 heat warning applies until Wednesday evening and affects all regions below 800 meters. Elderly people, small children and people with pre-existing conditions should avoid direct sunlight.
From Thursday, the weather will change: the probability of thunderstorms will increase significantly, especially in the south and in the Alps. However, individual warm thunderstorms are possible even earlier.
