Travel and Terrain Advice
There is a danger of storm slabs due to cohesive snowfall. The higher the elevation, the lower the temperature, so consider that the resolution of instability will only proceed slowly, so please do not lift your vigilance even if snowfall has subsided. When visibility is low, it is difficult to notice hazards above you. Always think about whether there is a large occurrence zone or if you are inside the avalanche runway or deposition area. The snow is deep and it is difficult to move around without skis. In such a case, even in a small terrain, if there is a trap of the terrain below the slope, it will be a serious outcome. Please ask for appropriate group management, such as acting while maintaining contact with a sense of distance that allows you to see your friends.
