Travel and Terrain Advice
Beware of triggering storm slabs in open areas where there are few trees or sudden changes in slope. Wind slabs may form just below the ridge at higher elevations where the wind is more susceptible. At lower elevations, be aware of open glide cracks and the possibility of glide avalanches from cliff-like slopes with thin snowpack. Do not enter the lower part of such slopes or pass through them quickly. When regrouping after skiing, try to do so off avalanche terrain and in the safest place possible, such as on top of a ridge.

概要
Avalanche
Yesterday (4th), there was a report of a small number of human-triggered wind slabs (size 1) observed just below an open ridge in a forested area.
Snowpack
Snowfall that began last evening is expected to be about 20-30 cm at higher elevations. Since the wind was weak at the beginning of the fall, it is suspected that a low-density layer is forming at the bottom, so care should be taken in bonding the boundary surfaces. In addition, wind slabs are expected to form just below the ridge due to southerly winds that increased during the night. crusts buried on the 3rd are present in all directions, at least below 1500 m elevation. Also, the movement of glides at lower elevations should be noted.
Weather
As of 4:00 pm, the temperature is -1.1°C at Amedas Fujiwara. 11 cm of snow has fallen in the past 12 hours, and it is still snowing weakly. The Japan Meteorological Agency is forecasting snow and rain as a low pressure system moves from the southern coast of Honshu to the east of Japan, but it will gradually become cloudy from midday.
