Travel and Terrain Advice
Be wary of all-level avalanches at low elevations, regardless of your direction. A route that skates at high altitudes and enters Tanisuji in the second half of the tour is also common in the Hakuba Mountains. At that time, the snow on both sidewalls of the valley is likely to be quite unstable, so please climb back and consider a different route depending on the situation. Wet snow blocks are very heavy, so just hitting a small object can cause fractures, etc. Even near the forest limit, there are places on the southern slopes where glide cracks are contained. You cannot see it from the top of the slope, so be sure to check the situation from below beforehand. Have a safe day

概要
Avalanche
An Glide avalanche of size 2 was observed yesterday (15th) in the below treeline.
Snowpack
The early morning rainfall yesterday (15th) ended in a short time and did not have that much impact. However, high temperatures continue, and glide cracks have expanded and are in a state of instability. At low altitudes, the surface layer of the snow cover has not yet become completely rough snow, so it is a stop snow that contains a lot of water and a lot of water during the day. At high altitudes, strong westerly winds blew yesterday, resulting in a hard snow surface situation.
Weather
The Japan Meteorological Agency predicts southern winds, later, north winds, sunny, sometimes cloudy, and a high temperature of 20°C (elevation 418m) for the northern part of Nagano prefecture. At the foot of Mt. Hakuba (elevation 703m), the temperature is -0.7℃ (as of 5:00), and there is no new precipitation in the past 12 hours. Yesterday, 10.8 degrees Celsius was recorded at 13:00.
