Travel and Terrain Advice
Due to strong winds during the day and night yesterday, please be aware of snow bonding on steep slopes just below the ridge and branch ridges where wind slabs are likely to form. At higher elevations where bonding is less likely to progress, be careful to induce storm slabs. Be careful on extreme steep slopes with few trees to support the snowpack and rapid changes in slope.

概要
Avalanche
Yesterday (13th), there was a report of a human-triggered storm slab avalanche size 1 observed on a steep southeast-facing slope in the Kagura area, and on the 11th, several human-triggered storm slab avalanches of size 1-2.5 were observed on steep slopes in the Tanigawadake area.
Snowpack
Snowfall during the day yesterday was poorly bonded, and avalanches were occurring due to human stimulation, but bonding is expected to progress gradually. bonding in the upper part of the crust that was buried on the 13th is improving, but future bonding may be worse in areas with locally low snow cover. Strong winds from the north to the west were observed during the day and night yesterday, which is expected to move the snowpack and form wind slabs on steep downwind slopes.
Weather
As of 5:00, there has been no snowfall in the past 12 hours at Ameda Fujiwara, and the snowpack is beginning to settle. The Japan Meteorological Agency is forecasting clear skies and cloudy nights due to a continuing high pressure system in the west and low pressure in the east, and the influence of a pressure trough and moist air.
