Travel and Terrain Advice
Conditions that require careful route selection even in low elevation bands. Note the triggering of unadvanced storm slabs in the joining of 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
There was no information about observing the avalanche yesterday because there were no visitors
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 -5.4℃. Snowfall has continued for the past 12 hours, but settling has progressed and the amount of snow has not increased. Snowfall continues around the area. According to the Japan Meteorological Agency's announcement at 17:00 on the 23rd, the winter type of atmospheric pressure will continue, and it will be affected by the valley of atmospheric pressure, so it will be cloudy in the northern part of Gunma prefecture and it will occasionally be sunny from early afternoon, and there will be places where it will snow until evening.
