Travel and Terrain Advice
It is a very dangerous condition, and it is a difficult day to act due to too deep snow. Even in the forest zone, be vigilant of the occurrence areas and runways in the forest, and do not neglect your attention to your upward side. It takes a sufficiently large margin of safety and requires conservative routing and decision-making. Also, places that are not usually too dangerous, such as hollows, can also become “traps in the terrain” due to deep snow. Even if you have enough experience, it is a good day to enjoy fresh snow in the ski area rather than in the mountains. When doing so, please observe the open places and try to skate with your companions. Have a safe day

As of yesterday, there was a lot of snowfall, and point-generated avalanches on steep slopes without wind, and surface avalanches responded sensitively to human stimuli in places with plate-like characteristics due to wind and time lapse. Please consider this situation the same today.
