Nationwide warning day on September 11


The nationwide warning day takes place every second Thursday in September.

It is a joint exercise by the federal government, the federal states and participating districts, independent cities and municipalities.

What is the aim?
The purpose of the nationwide warning day is to test processes and interfaces and to improve them afterwards. At the same time, accompanying information is intended to draw attention to the topic of warning, warning channels
and self-protection. The more familiar you are with the topic of warning and risks, the more effectively you can act in a dangerous situation and protect yourself and others.

What happens on Warning Day?
At around 11 a.m., a test warning is triggered centrally via the National Warning Center in Bonn using the Modular Warning System (MoWaS). Participating municipalities trigger their local warning devices decentrally. These can be sirens, for example. There is no danger to the population and no need for action.
A warning is issued via MoWaS at around 11.45 am. No all-clear function is currently planned for Cell Broadcast.
