Overview
- The water police reported crowds walking on frozen sections off Rügen on Sunday despite repeated warnings that uneven sea ice can fail without notice.
- Official assessments show increasing ice thickness in coastal waters, with more than 20 centimeters measured on the eastern approach to Stralsund and additional piling in places.
- Icebreakers remain active, with the Arkona deployed to free stuck vessels off Rügen and WSA units supporting runs through the Bodden waters.
- Navigation is restricted in some coastal areas, including night‑time bans and the removal of buoy lights, while WSA prioritizes key port approaches such as Mukran, Rostock, Lübeck and the Kiel Fjord.
- Regular ferry service to Hiddensee has been curtailed, with essential supplies delivered by icebreaker and passenger transport limited to emergencies.
