Travel and Terrain Advice
On slopes with glide cracks, the risk of glide avalanche is elevated, so be sure to keep a long distance from those slopes. Be vigilant on snow blocks that remain on cliffs and steep slopes. Loose snow avalanches caused by wet snow can also occur in wooded areas if the slope is steep enough. Even if you are in the forest, consider whether there is an avalanche track there. Avalanche danger at higher elevations is influenced by the amount of rainfall and is highly uncertain at this time. Today may be a good day to relax in the hot springs.

概要
Avalanche
Yesterday (March 9), numerous loose snow avalanches were observed at lower elevations. There were also reports of glide cracks expanding or occurring in new locations.
Snowpack
Yesterday, 17.4°C (14:00) was recorded at Amedas Hakuba. Since then, temperatures have remained above plus 3°C until this morning, and it has been raining since this morning. This has resulted in a large amount of melt water, which has greatly reduced the snowpack intensity at lower elevations.
Weather
The Japan Meteorological Agency is forecasting winds from the south, then from the north, rain, cloudy before noon, then sunny, with a high of 17°C (418 m elevation) for northern Nagano Prefecture. At Amedas Hakuba (elevation 703 m), the temperature is 5.4°C (as of 5:00) and it is raining.
