Excerpt

In the end of October 2014 heavy rainfall affected south-western Norway and caused the worst flooding in the area for more than hundred years.The worst affected area was inland Bergen and around Voss. In the valley around Flåm many houses fell down in the stream as the river eroded its banks.
