Travel and Terrain Advice
It is difficult to act due to heavy snowfall, and careful route selection is necessary even in the lower elevation zone. Note the triggering of storm slabs on steep slopes. It is necessary to pay attention to triggering in places where the slope changes rapidly or on open steep slopes with few forests. Even if you are at a low slope in the forest belt, be aware of the possibility of avalanches from the overhead outbreak zone. It is forecast that snowfall will continue in the future. Pay attention to changes in snowfall and wind effects and act cautiously.

概要
Avalanche
Since there were few people entering the mountain yesterday, there is no information on observing the avalanche.
Snowpack
There is a layer with low density and poor coupling in the snowfall until the 19th, and the layer was buried deeper (170cm or more in the Kagura area) due to the stormy weather this time, so there is a possibility that the scale will increase when an avalanche occurs. The amount of snowfall increases in the high elevation zone, so you need to be more careful.
Weather
The temperature at AMeDAS Fujiwara as of 4:00 a.m. The snowfall in the past 12 hours is 14 cm. Snowfall 28 cm for the past 12 hours at AMeDAS Yuzawa. Snowfall continues around the area. According to the Japan Meteorological Agency's announcement at 17:00 on the 22nd, it will continue to be winter-type, but due to the influence of barometric troughs and chills, the northern part of Gunma prefecture is forecast to be cloudy and sunny from early afternoon, and there are places where it snows.
