Travel and Terrain Advice
Wind slabs may form just below the ridge at higher elevations where the wind is more susceptible. At lower elevations, be aware of open glide cracks and the possibility of glide avalanches from cliff-like slopes with thin snowpack. Do not enter the lower part of such slopes or pass through them quickly. When regrouping after skiing, try to do so off avalanche terrain and in the safest place possible, such as on a ridge top. Snow is beginning to fall at higher elevations and a winter pressure pattern is forecast. Increased snowfall and winds in the future will increase the danger level. Please be aware of changing conditions around you.

概要
Avalanche
Yesterday (5th), there were no new avalanche bulletins reported, but there was also little information.
Snowpack
Snowfall up to yesterday was about 20-30 cm in many places. New snowfall is beginning to accumulate on top of it, and crusts may exist on the boundary surface. There is a suspicion that a low-density layer is forming at the bottom of yesterday's snowfall, so keep an eye on the bonding of the boundary surface. Westerly winds increased during the night and may have formed wind slabs just below the ridge. Also note glide movement at elevations where rain is falling.
Weather
As of 4:00 pm, the temperature is 1.8°C at Amedas Fujiwara. Cooler temperatures during the night. Rain is falling in the vicinity. Around 1300 m elevation, there was about 2 cm of snowfall. The Japan Meteorological Agency (JMA) is forecasting that a low pressure system will move northeastward east of Japan, creating a westerly high and easterly low pressure pattern, making it generally cloudy at the foot of the mountains in northern Gunma Prefecture, with snowfall in some areas from midday.
