The damage from heavy snowfalls includes not only disasters specific to heavy snowfall areas, such as avalanches and accidents involving falls during snow removal, but also disasters that occur outside of heavy snowfall areas, such as traffic accidents due to frozen road surfaces, accidents involving falls while walking and accidents during leisure activities in the snow.
