Travel and Terrain Advice
Pay attention to the presence of storm slabs on steep slopes, which remain at high elevations. Care should be taken to induce in places where the slope changes sharply or on steep slopes with sparse trees. Be careful of “terrain traps” such as deep slopes, cliffs, rocks, standing trees, etc., that increase damage even if the size of the avalanche that occurs is small. The Japan Meteorological Agency is forecasting mass snowfall in the future. Be aware of changes in the weather and act.

概要
Avalanche
Yesterday, several naturally occurring surface avalanches of size 2 that occurred during stormy weather were observed on slopes from east to southeast near forest limits, but details are unknown.
Snowpack
Due to the snowfall accompanied by strong winds the other day, the crust is buried on the slopes closer to the south, and it is expected that the snow accumulation that is 100 cm or more on the high altitude has progressed to settling.
Weather
As of 6:00, the temperature is -9.7℃ at AMeDAS Fujiwara. According to the Japan Meteorological Agency's announcement at 5:00 on the 20th, it is forecast that it will be cloudy in the northern part of Gunma prefecture and snow in the evening as the winter-type atmospheric pressure arrangement gradually intensifies and is affected by the chills in the sky and the valleys of atmospheric pressure.
