Travel and Terrain Advice
This is a very dangerous avalanche condition. Avoid large open slopes, even at low elevations. It is a state where avalanches of a potentially large scale can occur. Even if you are in the forest belt, consider whether there is a large outbreak zone at the top, and pay sufficient attention to the local occurrence area or runway in the forest. Also, do not enter the valley line with a large outbreak zone at the top. Avalanches of size 3 flow down quite normally with an elevation difference of 1,000 m. Avalanches of this magnitude often run up a slope opposite to the side where they occurred. It's not safe because you're in a forest. For those who are inexperienced, the inside of the ski resort is a fun situation. Ski patrols manage avalanches every day, so please protect the area where you can slide and slide in pairs with your friends when skiing in fresh snow areas.

概要
Avalanche
There was also stormy weather yesterday (13th), and no new avalanches were reported.
Snowpack
Snowfall has exceeded 100 cm in the past 3 days in the vicinity of the below treeline (elevation 1,000 m). Beneath a series of consolidated snowfalls, there is a melting frozen layer at low elevations and a hard old snow surface at high elevations, and potentially large avalanches can occur. Even if the snowfall has weakened, there is a storm of westerly winds blowing in the Alpine. It is necessary to pay close attention to the slab that the wind descends on the valley muscle and forms.
Weather
The Japan Meteorological Agency is forecasting northern Nagano prefecture's northern wind, snow, cloudy from the evening, and a maximum temperature of 0℃ (elevation 418m). At the foot of Mt. Hakuba (elevation 703m), the temperature is -6.2 ℃ (as of 5:00), and snowfall of 40 cm was recorded from noon on the 13th to the early dawn of the 14th. The Meteorological Agency announced a heavy snow warning (up to 40 cm in 12 hours) for Hakuba and Otari villages at 4:58 in a continuous form until 12:00 today.
