Avalanche Problem
ストームスラブ Storm slab
New snow accumulation has been higher than expected over the last few days. Testing of the new/old snow interface is required especially on southern aspects as this latest new snow will have fallen on a crust created during sunny periods.
点発生乾雪雪崩 Dry Loose snow
Loose dry avalanches will likely occur by human trigger in steep above terrain. Be mindful of terrain traps below you.
概要
Avalanche
A human-triggered size 2 (enough to bury a person) was recorded through gate 5 at Niseko Untied on the the 21st of February. The rider was was not caught and traversed out of the slide path.
Snowpack
Periods of broken sunshine over the previous few days has created a sun crust on the southerly slopes. We have received up to 50cm in the early part of the week with higher total in the North of the range. The mid to lower snowpack appears to be well bonded with any concerns within the latest new snow.
Weather
Calm condtions will round out the week with light to moderate west to north west winds, snowfall will continue in the coming days.
