Travel and Terrain Advice
Note the new storm slab that exists on the steep slope. Since the coupling in the fresh snow is not progressing, attention should be paid to inducing in places where the slope changes rapidly or on open steep slopes where trees are sparse. We recommend that you act in places with low slopes in the forest belt. Pay attention to the presence of the outbreak zone of the overhead slope even if you are in a place with a low slope. A large amount of snowfall is forecast due to the strengthening of the winter-type atmospheric pressure arrangement. Pay attention to changes in weather, such as an increase in snowfall or the effects of wind in the future.

概要
Avalanche
There are no reports of observing a new avalanche yesterday
Snowpack
Low-density snowfall was observed on the surface layer of the snow cover yesterday, and snowfall from this morning is on top of it, so attention is needed to combine the boundary surfaces. Observed on the 2nd, the less dense layer sensitive to human stimuli is gradually settling and raising the bond. In the middle layer of the snow cover, bonding proceeds, and no pronounced fragility has been observed.
Weather
As of 4:00, the temperature is -4.6℃ at AMeDAS Fujiwara. Snowfall for the past 12 hours is 1 cm. Strong snowfall continues in the vicinity. According to the Japan Meteorological Agency's announcement at 17:00 on the 4th, the winter type of atmospheric pressure has strengthened and is affected by the cold, so the northern part of Gunma prefecture is forecast to be cloudy and occasionally snowy.
