Deutsche Bucht
The flood was caused by the "Vincinette" low-pressure system, approaching the German Bight from the southern Polar Sea. A European windstorm with peak wind speeds of 200 km/h pushed water into the German Bight, leading to a water surge the dykes could not withstand. Breaches along the coast and the rivers Elbe and Weser led to widespread flooding of huge areas. In Hamburg, on the river Elbe, but a full 100 km away from the coast, the residential areas of Wilhelmsburg were the most affected.
