Overview
- Rhineland-Palatinate ran its second state Warntag on March 12 with a 10:00 test alert and a 10:45 all‑clear, both sent via the modular warning system and Cell Broadcast for the first time.
- Bavaria reported the statewide probe was mostly trouble‑free, though alerts arrived minutes late for some users depending on their mobile provider.
- The Bavarian all‑clear was also sent via Cell Broadcast for the first time at the lowest alert level, which meant it could appear silently or not show for some handset settings.
- Local coverage varied: Munich intentionally had no siren alerts, while Aichach‑Friedberg sirens are still configured for fire service use only and are slated for future civil‑protection upgrades.
- Participation in Rhineland‑Palatinate included Frankenthal and nearby communities using sirens, the NINA and Katwarn apps, a mobile backup siren, and Cell Broadcast, while BBK guidance stressed supported phones and current OS versions (Android 11, iOS 16.1) for reliable receipt.
