Travel and Terrain Advice
Watch out for wind slabs that exist on steep slopes just below the ridge and branch ridges. Do not induce newly formed windslabs because they are not yet bonding. Be more cautious of wind slabs at higher elevations with more snowfall, more susceptibility to wind, and less advanced bonding, as these wind slabs are larger in size. Poorly bonding layers have been observed at the boundaries of past stormy snowfalls. Beware of induced storm slabs on steep slopes. Exposed "terrain traps" such as deep streams, cliffs, rocks, and standing timber that can increase damage even if the size of the avalanche that occurs is small. Be careful of falling into gully and stepping through snow cover.

概要
Avalanche
No new avalanches observed yesterday (2nd)
Snowpack
The recent rainfall affected approximately less than 1000m. The snow surface melted-Freeze and then froze. New snowfall was deposited on top of the old snow, and the snowfall was moved by strong winds from the west to the northwest, forming wind slabs along the ridges and just below the ridges, and blowing away to expose crusts in wind-swept areas. At higher elevations that have not been affected by rainfall, a low-density, poorly bonded layer is sandwiched between the old snow and the boundary surface. No fragility within the old snow has been reported.
Weather
As of 4:00 pm, the temperature at Amedas Fujiwara is -2°C. Light snow continues to fall with wind in the vicinity. The Japan Meteorological Agency is forecasting cloudy skies at the foot of the mountain and clear skies from midday, as the area is expected to be covered by high pressure but affected by a pressure trough and moist air.
