In Switzerland, Meteo Schweiz normally counts 200’000 to 500’000 lightnings every year. On June 7th 2015, the system counted over 80’000! In that evening, a heavy thunderstorm moved over most parts of Switzerland. I have not been able to take good pictures myself, but Michael Uebelhart shared that one from the Bürgenstock overlooking the Lucerne area with me:
Happy Flashing 🙂
PS: Thunderstorms with heavy rain like that one are really dangerous: In that night and the area of that lightning struck, a mother (age 32) and her child (age 5) died in the flooded basement of their house :-(.
