Overview
- DWD issued high-level glatteis warnings with explicit danger-to-life alerts and urged people to avoid travel, with elevated risk persisting in the east and southeast into early Tuesday.
- Air travel was curtailed as Frankfurt canceled about 98 to 100 flights, while Munich and Nuremberg reported additional scrubs and passengers were told to check status and allow extra time.
- Deutsche Bahn reduced speeds on key long‑distance corridors such as Hannover–Frankfurt, Wolfsburg–Berlin and Köln–Frankfurt, skipped Braunschweig and Hildesheim on Berlin–Frankfurt ICEs, and saw regional cancellations in Niedersachsen and Hamburg.
- Schools moved to distance learning or closed widely, including across North Rhine‑Westphalia, Niedersachsen and Bremen, with Brandenburg suspending the in‑person requirement for Tuesday.
- Police reported numerous ice‑related crashes including a fatal A6 collision near Nuremberg, a mass pileup on the B173 in Oberfranken, and multiple accidents on the A7 near Hamburg, as winter and emergency services worked extended shifts.
