Travel and Terrain Advice
At higher elevations, be aware of bonding storm slabs forming on steep slopes. At lower elevations, be aware of open glide cracks and the possibility of glide avalanches from cliff-like slopes with thin snowpack. Temperatures are currently dropping, but the effects of warming up to 2 days remain in areas where cracks are open. Please do not enter the lower part of such slopes or pass through them quickly. When regrouping after skiing, try to do so in the safest possible place, such as off avalanche terrain and on top of a ridge.
Avalanche Problem

Watch out for open cracks and cliff-like terrain with thin snow cover.
概要
Avalanche
Yesterday (3rd), the occurrence was unknown due to lack of information; on the 2nd, there were reports of multiple observations of below treeline glide avalanches and loose snow avalanches of point-occurrence wet avalanches.
Snowpack
The surface layer of snowpack that melted due to rising temperatures up to the 2nd was frozen during the night, and 10-20 cm of new snowfall from yesterday was placed on top of it, and settling is expected to continue gradually, but bonding is unknown. The middle to lower layers of the snowpack are settling and bonding, but the boundary with the ground surface is wet, so the movement of glides at lower elevations is expected to continue.
Weather
As of 4:00 pm, the temperature was -8.9°C at Amedas Fujiwara. There has been 7 cm of snowfall in the past 24 hours, with about 10 cm near 1300 m elevation. The Japan Meteorological Agency is forecasting cloudy skies and snow at night due to the influence of a front and low pressure system.
