Travel and Terrain Advice
Avalanche danger remains high due to heavy snowfall. Strong cold air is moving in, and snow sintering and stabilization is progressing only slowly. Those entering the forest at lower elevations should check terrain maps for large start zones above them. In addition, there are many hazards at lower elevations that are hidden in this new snow, such as glide avalanche tracks, glide cracks, and holes in stream bottoms. Please act with a larger safety margin than usual. This is a good day for inexperienced groups to enjoy the fresh snow in the ski area. Please stay out of the closed areas and enjoy safe skiing. When skiing in deep snow, please enjoy skiing with more than one person monitoring each other.

概要
Avalanche
No new avalanche bulletin was reported yesterday (27th), but information is limited due to the small number of people entering the mountain.
Snowpack
The snowfall cycle that began on the 26th has brought snowfall accumulations of up to 100 cm. Since early this morning, the snowfall has intensified again. The previous snowfall has been settling, but the new snow is low density and easily carried by the wind, forming a soft slab on the downwind side.
Weather
Today, a winter pressure pattern is expected to continue, with pressure troughs and cold air. As a result, it is forecast to be snowy and cloudy in the northern part of the country, with a daytime maximum temperature of 2 °C. At the AMeDAS Hakuba (elevation 703 m), the temperature was -3.0 °C (as of 5:00 pm), and 42 cm of snow had fallen in the past 24 hours. The Nagano District Meteorological Observatory forecast 50 cm of snowfall in the next 24 hours until 18:00 on the 28th at 16:25 on the 27th along the mountains of the Daihoku region.
