Travel and Terrain Advice
Beware of unstable snow remaining in extreme terrain, etc. Moderate northwesterly winds were blowing continuously at high elevations, so it is necessary to be careful about the formation of new slabs. Also, today there is a forecast that the south wind will enter and the temperature will rise. Please do not enter the terrain with glide cracks at low elevations, and move quickly when passing under it. In places where there is no influence of wind and sunlight, there is snow where you can enjoy the feeling of sliding. Have a safe weekend while being aware of the speed you can control.
