Natural hazards are limited compared with many world regions. The main weather-related issues tend to be autumn and winter storms, heavy rain events, localized flooding in drainage systems, and occasional snow or ice disruption. Extreme heat is less common than in southern Europe, though heatwaves have become more notable across Germany in recent years.
