Travel and Terrain Advice
This is a day of varying danger depending on the degree of snowfall and wind. If wind and snow increase in the future, expect the danger level to increase accordingly. Choose your terrain carefully and check the bonding of new and old snow. Melt-Freeze crusts are buried on steep south-facing slopes. Glide cracks are forming in various locations from previous years. Please consider the possibility that they are hidden by new snow and act accordingly.
Avalanche Problem
ストームスラブ Storm slab
Note that at higher elevations, the surface layer of snow cover will be more of a slab feature due to the winds. Winds are currently southwest to west, but are forecast to shift to northwest later in the day. Please pay attention to the snow movement associated with that wind direction change.
