Travel and Terrain Advice
It is a very dangerous condition, mainly on the north side of Hakuba Valley. Even if you are in the forest zone, be vigilant of outbreaks and runways in the forest, and do not neglect your attention to your upward side. It takes a 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. If you don't have enough experience, this is a good day to enjoy the fresh snow in the ski resort. When doing so, please observe the open places and try to skate with your companions. Have a safe day

概要
Avalanche
Yesterday (5th), point avalanches and storm slabs of size 1 due to continuous snow have been observed in the below treeline. There is no information on high elevations due to stormy weather.
Snowpack
There is a lot of snowfall centered on the north side of Hakuba Valley. As of yesterday, there was snowfall of about 50 cm in the below treeline, and point avalanches on steep slopes without wind and surface avalanches respond sensitively to human stimuli in places with plate-like characteristics due to wind and time lapse, etc. I did it. Please consider this situation the same today.
Weather
The Japan Meteorological Agency is forecasting northern Nagano prefecture's northern wind, snow, occasional, cloudy, and maximum temperature of -1℃ (elevation 418m). At the foot of Mt.
