Travel and Terrain Advice
Note the storm slabs present on the extreme steep slopes of the high elevation zone. It is necessary to pay attention to triggering on steep slopes where the slope changes rapidly. Be careful of “terrain traps” such as cliffs and deep rivers, which increase damage even if the scale of avalanches that occur is small. It is a forecast to clear up. Be aware of the possibility of wet snow point avalanches from large steep slopes to the south.

概要
Avalanche
Yesterday, there was a report that a surface avalanche size 1 was observed on the southeastern slope near 1850 m by human inducement.
Snowpack
About 20 cm of snowfall until yesterday is placed on top of the snow cover of the other day's stormy weather where settling progressed and bonds were raised. Crusts are observed on the boundary surface of the steep slope towards the south. The bonding of this interface is good, but there is an area where recrystallization is observed, and attention should be paid to the decrease in bonding strength in the future.
Weather
There is no data update on AMeDAS Fujiwara since 7:00 yesterday. According to the Japan Meteorological Agency's announcement at 17:00 on the 11th, it will be covered by high pressure, but due to the influence of a valley of atmospheric pressure, it is forecast that it will be sunny and sometimes cloudy in the northern part of Gunma prefecture.
