At higher elevations, watch for the presence of locally formed wind slabs on extreme steep slopes just below the ridge. At lower elevations, due to warmer temperatures, be alert for glide avalanches from extreme steep slopes with thin snowpack or glide cracks. Do not enter or pass quickly through the lower portions of such slopes. When regrouping after skiing, try to do so off avalanche terrain and in the safest place possible, such as on top of a ridge. Stormy weather is forecast for the coming days. Please be aware of changing snowfall amounts and wind-driven snow movement.
Be careful of the steep slope just below the ridge.
Beware of extremely steep slopes with thin snow cover and open glide cracks.
Yesterday (16th), a report of a loose snow avalanche (size 1) observed on a steep southerly slope.
New wind slabs are expected to form just below the ridge due to the westerly winds since dawn. The middle part of the snowpack is settling and bonding. Yesterday, crusts formed on all slopes in all directions below 1400m. At lower elevations, crusts are thin and weak due to weak nighttime cooling.
As of 5:00, the temperature at Amedas Fujiwara is 0.2°C. No new snowfall in the past 24 hours. The Japan Meteorological Agency is forecasting cloudy skies and snow in the foothills of northern Gunma Prefecture from early afternoon, as the area is expected to be gradually affected by a winter pressure pattern and a pressure trough.
