In August 1971 I witnessed a category 4 hurricane ("ouragan" in French [1]) that wrecked Vallée de Joux, a clock-making valley in the Swiss Jura (a little bit North of the Alps). All trees were down, similar to the landscape near Mount St Helens after its most recent eruption. There are records in the same location of another hurricane in August 1890, as well as one in 1624.
