Reporting level 3 signals that significant flooding and road closures may occur. These warnings are crucial to inform citizens in a timely manner and take appropriate action.
Measuring points in the area
The Marburg-Biedenkopf district is equipped with eight measuring points that are used to monitor the water level. The locations are chosen to cover both urban and rural regions. These include Marburg, Biedenkopf and Niederwetter, among others. Reliable measurements are particularly important in order to be able to respond to changing conditions in a timely manner, as mentioned on the hessenschau.de website.

February 2020 and January 2018 also set high standards with over 430 cm and 480 cm. The record value of 533 cm dates back to 1984. These numbers illustrate the danger posed by extreme weather events.
