Overview
- Freezing rain produced treacherous roads from North Rhine-Westphalia to Rhineland-Palatinate before milder air eased conditions in the west and the risk moved toward central, eastern and southeastern states.
- Frankfurt Airport canceled about 100 of more than 1,000 scheduled flights and cautioned travelers to expect delays despite extensive de-icing and clearing operations.
- Deutsche Bahn lowered top speeds on high‑speed corridors including Cologne–Frankfurt, Hannover–Frankfurt and Wolfsburg–Berlin, skipped Braunschweig and Hildesheim on Berlin–Frankfurt ICEs, and reported localized regional disruptions.
- Schools shifted to distance learning in North Rhine-Westphalia, Lower Saxony and Bremen, several Bavarian districts canceled presence classes, Hamburg kept classrooms open, and Brandenburg suspended attendance requirements for Tuesday.
- Police logged numerous ice‑related crashes, including a fatal collision on the A6 in Middle Franconia and serious incidents in NRW and northern states, as the ADAC urged people to avoid nonessential driving.
