Travel and Terrain Advice
At higher elevations, where bonding is less likely to progress, watch for induced wind slabs formed on extreme steep slopes just below the ridge and snow avalanches from the ridge. At lower elevations, where temperatures are warmer, watch for glide avalanches from extremely steep slopes with thin snowpack or glide cracks, and loose snow avalanches from large steep slopes. Do not enter or pass quickly through the lower part 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.
Avalanche Problem
ウインドスラブ Wind slab
Beware of extremely steep slopes just below the ridge.
全層雪崩 Glide slab
Beware of open glide cracks and cliff-like slopes with thin snow cover.
概要
Avalanche
Yesterday (14th), there was a report of a human-triggered wind slab avalanche (size 1) observed on an extremely steep slope in the below treeline.
Snowpack
Snowfall accompanied by strong westerly winds through the 13th has formed wind slabs just below the ridge, but bonding is progressing at lower elevations. At elevations below 1,200 m, crusts are forming on the boundary surface due to the effects of rainfall at the beginning of the day, and further bonding should be monitored. The middle part of the snowpack is expected to settle and bond gradually.
Weather
As of 4:00 pm, the temperature at AMeDAS Fujiwara was -2°C. Around the area, about 2 cm of snow fell during the night. The Japan Meteorological Agency is forecasting clear skies and cloudy nights due to a high-pressure system, but subject to the effects of a pressure trough and moist air.
