Travel and Terrain Advice
The forested areas are still bushy and avalanche terrain is difficult to see, but at higher elevations, the terrain is beginning to fill in with more snow. Do not be misled by the atmosphere of the place you are in, and check the terrain map to see if there are any large start zones above you. Avoid "terrain traps," where even a small avalanche can cause deep burial. Also, remember that below the treeline, even on seemingly skiable slopes, the bushes have not yet fallen over, so there is a danger that your skis could get under a branch and cause you to fall, or that you could fall into a hole in the gully.

概要
Avalanche
No new avalanches were observed yesterday (December 24).
Snowpack
New snow accumulation due to a series of stormy weather that began with the passage of a low-pressure system on December 22 has reached 80 cm in the upper part of the below treeline. In the elevations below treeline, the snow has been redistributed under the influence of strong north~northwest winds. The snow cover from the treeline to below treeline is not yet sufficient to fill the terrain. There are dangerous holes in the creek.
Weather
The Japan Meteorological Agency is forecasting a persistent winter pressure pattern over northern Nagano Prefecture. Therefore, it is forecast to be cloudy and snowy over a wide area in the evening, with a maximum temperature of 4°C (418m elevation). The temperature at Amedas Hakuba (elevation 703m) is -2.2℃ (as of 5:00).
