Niseko Avalanche Information - 2011.02.23

Grand Hirafu: Top - 395 Bottom - 200 Niseko Village: Top - 390 Bottom - 200Annupuri: Top - 350 Bottom - 220

All gates scheduled to open this morning, peak gates 2 & 3 at 9:30. Seek for ski patrol’s advice at the gates. Annupuri peak 6am: -8℃ and SSW13m/s wind. The southerly wind that started blowing from yesterday is slowly picking up. There is no new snowfall and the slopes are tracked out. Sun-exposed slopes surface are re-frozen during early morning and are in a difficult condition for skiing. Be careful and remain in control. The temperature is forecasted to rise above 0℃ at the base of the mountain again today. Beware also of glide-cracks (crevasses) that are hardly noticeable from above. There have been few reports of avalanches occurring from Feb 18th layer (1000m NE and NW slopes of Mt. Yotei). The surface snow density and weight is increasing due to the sun-effect and high temperature. Similar conditions avalanches are still to be considered, especially in south facing steep faces and other slopes where distinctive snow-layers are still present.
