Travel and Terrain Advice
High temperatures continue, so please stay away from slopes with glide cracks. Also, be wary of snow blocks that remain in extreme terrain, etc. When stopping, check the surroundings (especially upwards) so that you are not within avalanche terrain. Also, since glide cracks are almost always not visible from the top of the slope, there is a change in slope, and where the future cannot be seen, stop at a sufficient distance and check the condition of the slope ahead Sai The weather was slowly going downhill, and the good weather that continued was over. Have a safe day

概要
Avalanche
Traces of Glide avalanche of size 2 that seem to have occurred within the past 24 hours have been observed yesterday (16th).
Snowpack
Snow melting is progressing rapidly at the foot of the mountain due to the influence of high temperatures every day. The temperature continues to be high and positive from last night to this morning, so please consider the slopes with glide cracks in an unstable state. The effects of rainfall in the early morning of the 15th are up to the forest limit, and there are places where rain grooves are formed.
Weather
The Japan Meteorological Agency predicts north wind, sunny, cloudy, and high temperatures of 12°C (elevation 418m) for the northern part of Nagano prefecture. At the foot of Mt. Hakuba (elevation 703m), the temperature is 6.8℃ (as of 5:00). Yesterday, it recorded 15.2 degrees Celsius at 12:00.
