Due to the heavy thunderstorms on Monday evening, August 12, 2024, the Milibach in Brienz overflowed its banks at around 6:30 pm. The debris, consisting of stones, rocks and wood, caused a collector above the village to overflow and the debris flowed uncontrollably into the Seematte, Rybi and Steiner parts of the village and around the church. Buildings, parked vehicles, roads and public transport infrastructure were damaged.

The rain and thunderstorm cell that fell over the village on Monday evening also hit Brienz Rothorn Railway hard. 

A stretch of 2.2 kilometers shows severe structural damage to the route, the stone bed foundation and the drainage. In addition, the ballast is contaminated over a length of 1.4 kilometers.
