National Warning Day: What Everyone in Germany Needs to Know
On Thursday, September 10th, 2026, all kinds of alarms will be going off. It's a nationwide test.
Berlin, September 9th, 2026 (The Berlin Spectator) – Germany is set to conduct its annual “Warntag” warning drill this week, with emergency alerts scheduled to be tested on Thursday, September 10th. The test is coordinated by the federal government, the states, and local authorities to ensure that public alerts reach the population reliably. No cause for alarm should be taken if an alert goes out that day, as it is merely part of a planned exercise.
The Federal Office of Civil Protection and Disaster Assistance (BBK) outlines two key objectives for the drill: testing the technical reliability of Germany’s warning infrastructure and familiarizing the public with the various channels through which warnings are issued. By familiarizing citizens with how the system operates, the BBK argues that people can react more swiftly and effectively in an actual emergency.
During the drill, warnings will be disseminated through a variety of channels simultaneously, including cell broadcast messages to smartphones, dedicated warning apps like NINA and KatWarn, radio and television broadcasts, websites, social media, digital displays, and in many regions, sirens and loudspeaker vehicles. However, not every warning method is accessible everywhere; sirens, for instance, are not installed in all municipalities.
Residents should ensure that their warning apps are activated and that their location is enabled, so alerts can reach them regardless of the region.
In terms of sirens, a one-minute wailing tone, rising and falling, signals a local hazard, urging people to seek information through media channels. A one-minute continuous tone indicates that the hazard has passed. The Interior Ministry advises residents to monitor the situation through radio, warning apps, or official websites and to check on neighbors or family members if necessary.
This year marks a significant update, as the all-clear signal will be transmitted via cell broadcast for the first time. This capability, introduced on November 25th, 2025, was not utilized during last year’s Warning Day on September 11th. The BBK notes that all-clear messages will be automatically issued at the lowest alert level to prevent noise disruption, even though they are typically lifted through the same method and severity level used for issuing the warnings.
If you do not receive any warning, the BBK requests that you inform the authorities. From September 10th to 17th, a nationwide survey will be conducted to gather feedback on the effectiveness of the warning system.
