Wind slabs have been building with recent wind. Expect heavy wind loading in lee features.
Enjoy the fresh snow in simple terrain with no overheard exposure. Natural avalanche cycle is ongoing.
Wind slabs have been building with recent wind. Expect heavy wind loading in lee features.
This sits upon weak faceted crystals, sun crust or a dense layer that are perfect for slab avalanches. This layer will not react well to new loading, or even re-loading from wind.
Concern for steep extreme terrain
Bad visibility throughout the day. Several rumbles were heard from the steep headwall in the back of the basin today. On the drive home, there was visible debris below large features and a fresh crown on the SE aspect of tent ridge which ran in to the valley below where most skiers descend from tryst lake basin. Loose dry and sluffs were observed on any feature steep enough.
The storm produced. Field teams in the black prince area today found 70CM of new snow sitting overtop of a sun crust in the tree triangle. This amount seems highly drainage dependant as the weather stations in the burstall pass area recorded 30cm. This new snow now overlies the Jan 30th interface. Below the Jan 30th there is a mostly faceted snowpack to ground with a standout layer about 30cm off the ground of large depth hoar crystals.
Traveling off of established skin tracks at lower elevations is very challenging due to the weak nature of the snowpack. Once higher this becomes easier.
Tuesday:
Mostly cloudy with sunny periods, isolated flurries. Day time high of -9 with 50km West winds
