With regard to the storm surges on the German Baltic Sea coast, there are various classifications that are decisive in the event of a flood. While a normal storm surge is between 1.00 m and 1.25 m above the middle water level, heavy storm surges can reach values ​​above 1.50 m. The last serious storm surge in October 2024 caused damage of 56 million euros.

The responsible authorities appeal to the population to regularly consult the warning channels in order to be informed in good time.
