Nationwide warning day: Siren test in Ostallgäu on September 11th!
In the Ostallgäu region it is worth keeping an ear out for upcoming signals! On Thursday, September 11, 2025, at 11 a.m., the nationwide warning day will send a loud signal when a comprehensive warning message is sent to the population via the Modular Warning System (MoWaS). On most cell phones, the messages are distributed directly via warning apps such as NINA, KATWARN and Biwapp as well as via the Cell Broadcast warning channel. Only 45 minutes later, at 11:45 a.m., the all-clear was given - also via the same channels, although the all-clear via cell broadcast was still missing in this first phase. This campaign is not only a test run, but also a valuable opportunity for citizens to develop a feel for emergency situations and learn how to react correctly in an emergency.
As reported, the local sirens are being tested in this context in various cities and communities in Ostallgäu, including Buchloe, Obergünzburg, Günzach, Pforzen, Schwangau, Jengen and Roßhaupten. This is an important measure to check the functionality of the warning systems. After all, the warning day takes place annually on the second Thursday in September in order to test the technical systems and to make the population aware of warning signals.
An important day for security
“How well prepared are we for potential dangers?” is the central question of the warning day. The process is clear: At the beginning, the sirens ring with a rising and falling tone to warn the population. A continuous tone signals the all-clear. The day not only serves to uncover possible vulnerabilities in the warning infrastructure, but is also intended to provide incentives to familiarize yourself with the available warning channels.
- Cell Broadcast: Direkt aufs Handy, ohne zusätzliche App.
- Warn-Apps: NINA und KATWARN informieren über aktuelle Gefahren und geben wertvolle Verhaltenstipps.
- Sirenen: Dienen als traditionelle Warnsignale.
- Lautsprecherwagen und digitale Stadtinformationstafeln: Ergänzende Informationsmittel vor Ort.
Inform and prepare
Which smartphone do you have with you and how is it configured? Before the warning day, all citizens should check their smartphone settings. Cell Broadcast works on most newer devices, with Android from version 11 and iOS from 16.1. Another good idea is to get local information and ask what warning devices are being tested in your community.
The importance of this warning day cannot be overstated. It makes a crucial contribution to improving Germany's preparedness for disasters and promoting education among the population. Because those who are informed can react better in an emergency. For all those who would like to share their experiences with the warning day, there is the opportunity to do so via the survey www.warntag-umfrage.de to do.
All in all, it shows that the warning day in Ostallgäu is not just a test, but also an opportunity to actively address the issue of safety. Be there when the sirens sound and take advantage of the opportunity to be as prepared as possible!
