Terrorism / public attack vigilance
Avoid large, crowded events if possible; keep a low profile in tourist areas and be prepared to move quickly to a safe location.
U.S. Department of State advisory highlights terrorism as an ongoing threat in Germany and nearby attacks have been reported in regional media.
Infrastructure outage readiness
Carry a flashlight and extra phone power; have contingency plans (meeting points, paper directions) if local power or communications services are disrupted.
Local reporting notes an attack on power infrastructure and subsequent security hardening, indicating recent successful disruption to the electricity network.
Cold-weather travel
Allow more travel time, check footwear traction, and expect minor delays or service slowdowns during light snow periods.
MeteoAlarm alerts and the 7-day forecast show near-freezing temperatures with slight snow and snow grains on 15–17 Feb.
