Travel and Terrain Advice
Wind slabs are expected to form on higher elevation ridges and just below the branch ridges due to wind-driven snow movement since last night. Watch for induced wind slabs where bonding has not progressed. Also, be aware of open glide cracks at lower elevations and the potential for glide avalanches from cliff-like slopes. Do not enter the lower part of such slopes or pass through them quickly. When regrouping after skiing, try to remove the avalanche terrain and regroup in the safest place possible, such as on top of a ridge.

Beware of steep slopes on the ridge and just below the branch ridge.

概要
Avalanche
Yesterday (25th), visibility was poor and no reports of new avalanches observed.
Snowpack
The upper layer of snowpack is settling and bonding is rising. The upper part of the snowpack has been settling and binding is rising. On top of this is about 5-15cm of recent snowfall that has been affected by the wind, and strong northerly winds since last night are expected to move the snow and form a wind slab downwind. In the Kagura area, low-density snow and a strong temperature gradient are observed on the boundary with the old snow, and attention should be paid to the bonding in the future. The old snow on the southerly slopes is crusting. There are no reports of observed vulnerability from the mid to lower snowpack; glide crack movement and glide avalanches have been observed on steep southerly slopes up to two days ago.
Weather
As of 4:00, the temperature at AMeDAS Fujiwara is -3.0℃. There has been new snowfall of about 2-3 cm in the surrounding area, and snow is still falling weakly. The Japan Meteorological Agency is forecasting cloudy and sometimes sunny skies in northern Gunma Prefecture, with some snow showers until early afternoon, due to the influence of cold and moist air, although high pressure is expected to prevail.
