Braunschweig is testing disaster protection: nationwide warning day on September 11th!
On Thursday, September 11, 2025, the nationwide warning day will take place throughout Lower Saxony. In Braunschweig in particular, comprehensive checks of warning devices are on the agenda on this day. As news38.de reports, the Federal Office for Civil Protection is launching a test warning at 11 a.m. that is intended to reach all citizens. The aim is to test the functionality of the warning systems and ensure that the population can be warned in good time in an emergency.
Various channels are used here: The warning apps “NINA” and “BIWAPP”, cell broadcast and city information boards will provide citizens with current warning messages. Particularly noteworthy is the Cell Broadcast system, which has been sending warning messages directly via SMS to cell phones without a special app since February 2023. This ensures that over 50 million cell phones in Germany can be reached so that we can react quickly in an emergency.
Warning apps in focus
The NINA warning app is very popular in Lower Saxony. It offers comprehensive safety information on various dangerous situations and is available for all common mobile operating systems. In addition, it provides information not only about official warnings, but also about school closures and important local events. Other apps available include KATWARN and the German Weather Service's warning weather app, which provides valuable information about weather conditions. As niedersachsen.de notes, these apps are important tools for informing the population quickly and precisely in crisis situations.
The city of Braunschweig also appeals to its citizens to install the NINA app in order to be well prepared in an emergency. The test warnings on September 11th are intended not only to check the technical functionality, but also to increase the population's awareness of the importance of disaster prevention and early warning systems.
Pedagogical measures and future outlook
As indicated in the report by Deutschlandfunk Kultur, preventive education is a key to increasing the ability to act in crisis situations. The federal government and various institutions are committed to ensuring that a comprehensive early warning system is implemented for everyone in Germany by 2027. This goal should help save tens of thousands of lives and save immense costs.
This makes it all the more important to test and optimize existing systems today. In the future, not only storms, but also droughts and forest fires will be among the challenges that society faces. A comprehensive early warning system that integrates various technologies and communication channels is therefore more important than ever.
Stay informed and use the warning options offered to you so that you can react correctly in an emergency. Warning Day on September 11th is an excellent opportunity to familiarize yourself with the warning systems and equip yourself for an emergency.
