Niseko Avalanche Information - 2011.01.22

Current Official Snow Depths:

Grand Hirafu:
Top - 340
Bottom - 180

Niseko Village:
Top - 290
Bottom - 185

Annupuri:
Top - 240
Bottom - 200

Annupuri peak 6am: -14℃, W8m/s. 15cm of overnight snowfall.
W to WNW wind that was blowing at around 20m/s above 1000m yesterday morning has calmed down and is stagnating around 10m/s this morning. Although the snowfall amount varies on the slope orientation in 800m or lower areas, the overall condition seems to be in good shape. The snow condition is variable in slopes above 1000m, where wind-affected hard-pack, hard slabs and soft fresh snow can be found in the same slope. A relatively shallow surface slab avalanche risks is still to be considered in leeward steep slopes above 1000m. Personally evaluate the risks you’re taking before dropping into a slope. Be especially careful of the snow conditions in leeward gullies’ walls, around developed cornices and slopes with sudden gradient shift. Carelessly dropping into places like the Backbowl, many people dropping in the same slope all at once or traversing all the way underneath cornices have to be avoided unless you’re trying to deliberately cause an accident. All gates are scheduled to open this morning including Peak gates 2 & 3 at 10am. Seek for the ski patrol’s instructions at the gates.
