Travel and Terrain Advice
The season is progressing quickly and snowmelt is evident at lower elevations. Plan your activities with the expectation that the descent routes that were possible during the season may not be available. At higher elevations, be on the lookout for slip drops on frozen slopes in the morning. Glide cracks occur where the slope changes significantly. If you are on a slope where you cannot see what lies ahead, do not ski into the slope suddenly, but pause in a position where you can afford to do so and check what lies ahead. Snow is also breaking up on the ridge and just off the ridge. Climbers should not think that they are safe because they are on the ridge. Glide avalanches and snow block collapses are difficult phenomena to estimate the degree of irritation they may cause. Avoidance from hazardous elements should be considered first.

概要
Avalanche
Yesterday (March 24), there were few people entering the mountain and no brand new avalanche reports were received.
Snowpack
High temperatures and yesterday's rainfall have contributed to the melting of snow. At elevations around 1,300 m, the snow depth has decreased by about 20 cm over the past two days. This has resulted in the widening of glide cracks and the development of cracks in the snowpack, which is typical of the snowmelt season, even on relatively gentle slopes. Although temperatures are somewhat cooler than in the past few days, the intensity of the snowpack is decreasing, and therefore, we must continue to be vigilant for glide avalanches in Treeline and Below treeline areas.
Weather
The Japan Meteorological Agency is forecasting northerly winds, rain, and occasional cloudiness with a high of 11°C (418 m elevation) for northern Nagano Prefecture. At Amedas Hakuba (elevation 703 m), the temperature is 4.8°C (as of 5:00). Yesterday, at Amedas Hakuba, a maximum temperature of 12.7 °C (at 11:00) was recorded.
