Travel and Terrain Advice
Watch for bonding wind slabs on steep slopes just below the ridge and branch ridges. Although the expected avalanche size is small, there are exposed "terrain traps" such as deep streams, cliffs, rocks, and standing timber that can cause more damage. Be careful about falling into gully. Also, be mindful of group management, for example, to ensure that other skiers are not above or below you. Be aware of sudden changes in slope at higher elevations, and of triggering storm slabs on open, extremely steep slopes with few trees. Sunny skies are forecast during the day. Be aware of the possibility of loose snow avalanches from large south-facing steep slopes that are susceptible to solar radiation.

概要
Avalanche
Yesterday (6th), there was a report of a human-triggered slab avalanche (size 1) on an extremely steep north-facing slope near 2000 m and a few loose snow avalanches (size 1) on a steep slope near 1400 m. The avalanches were reported to have been caused by a human-triggered dry avalanche (size 1) on an extremely steep north-facing slope near 2000 m and a few loose snow avalanches (size 1) on a steep slope near 1400 m.
Snowpack
Wind slabs are expected to form on the ridge and just below the branch ridges due to the strong northerly winds that have been continuing since last night. The middle part of the snowpack is bonding and strengthening. In addition, at higher elevations, some crusts are gradually bonding, with the upper part of the crust that was buried on February 22nd being locally covered by a small crust.
Weather
As of 4:00, the temperature at AMeDAS Fujiwara is -1.5℃. There has been 1-2 cm of snowfall in the vicinity and it continues to be accompanied by wind. The Japan Meteorological Agency is forecasting cloudy skies and sunny skies in the morning and early afternoon due to a high-pressure system over the Sea of Japan, but subject to the effects of a pressure trough and moist air.
