Mountain base 6am: -7℃, 5cm snowfall. Moiwa800m: -9℃, WSW1.9m/s, 5cm snowfall, snowdrifts developed during the night. Annupuri1100m: -11.8℃, WNW2.3m/s, 250cm snow depth. Hirafu1000m: -11.7℃, N3m/s. Kucthan weather station: -7.4℃, 90cm snow depth. Benkei cape: NW5m/s, Kamui cape: NW6m/s, 1011hPa, 1.5m waves.

A strong cold air inflow with a westerly wind picking up overnight made snowdrifts develop drastically above 800m elevation. 40cm thick surface slab avalanches are to be expected in Osawa and Backbowl SE aspects, leeward knolls and cornice slopes during the morning. Similar hazardous conditions are present in surrounding mountains. Beware. A decent layer of fresh snow has blanketed the tree-runs, however still not quite bottomless powder conditions. Ride carefully. Some cracks are covered and difficult to see.

All gates are scheduled to open. Please follow the ski patrol’s instructions. The mountain is back to winter. Beware of poor visibility and do not ride the valley bottom carelessly. Have a great weekend.
