Sedimentation proceeds and bonds are rising in the middle layer of snow cover. On a steep south-facing slope with a low elevation, a crust is formed due to the influence of solar radiation on the 26th, and in places where there is a lot of snowfall in this stormy weather, about 60 cm is placed on it, and it gradually settling to form soft slabs. prospects

As of 4:00, the temperature is -4.0℃ at AMeDAS Fujiwara. There has been a 12cm snowfall in the past 24 hours, and snowfall continues around the area. According to the Japan Meteorological Agency's announcement at 17:00 on the 28th, the winter type of atmospheric pressure will continue, and due to the influence of barometric troughs and chills, the northern part of Gunma prefecture will clear up from cloudy morning to early morning, but there will be snow in the morning and evening.
