Travel and Terrain Advice
Climbers and skiers alike should be on the lookout for slip drops on icy slopes in the morning. During the day, be on the lookout for avalanches of wet snow on sunny slopes. Wet snow is very heavy and can easily trap your feet. If there are "terrain traps" lower down the slope, the consequences can be serious. At lower elevations, the snow has melted to the point where it is difficult to ski. Please be smart about the terrain in elevation zones where there is sufficient snow cover. The danger of glide avalanches continues and cracks have been reported at higher elevations. Keep a good distance from such slopes. Have a good day.

概要
Avalanche
Yesterday (March 27), a size 1 wet loose snow avalanche was observed on a steep slope receiving solar radiation.
Snowpack
There is about 5 cm of fresh snow in the high alpine, but as of yesterday, it had become wet on the south side, resulting in loose snow avalanches. Below 2,000 m elevation, the snow surface layer has become sufficiently wet up to about 30 cm due to previous rains. This creates conditions conducive to the occurrence of loose snow avalanches. Glide cracks have also been observed in alpine areas.
Weather
The Japan Meteorological Agency is forecasting northerly winds, cloudy and occasionally sunny with a high of 12°C (418 m elevation) for northern Nagano Prefecture. At Amedas Hakuba (elevation 703 m), the temperature is 1.2°C (as of 5:00). Yesterday, at Amedas Hakuba, a maximum temperature of 8.3°C (at 2 pm) was recorded.
