Avalanche Summary

On Monday a small size 1 avalanche was accidentally triggered by a skier near Big White. See the MIN report here.

On Sunday, a few small loose dry sluffs triggered by skiers were reported in parts of the region.

If you head into the backcountry please consider submitting a MIN post.

Snowpack Summary

10 to 20 cm of low-density storm snow from earlier in the week is covering a thin crust on sun-exposed slopes and surface hoar in wind-sheltered areas. In wind-exposed terrain at upper elevations expect to find variable wind-affected surfaces and potential small new wind slabs in leeward terrain. In wind-sheltered areas the snow remains soft and low-density, but small loose dry avalanches remain possible in steep areas. Otherwise, the upper snowpack is largely faceted, with a crust and in some cases surface hoar from late January buried 30 to 40 cm. The rest of the snowpack has no current layers of concern.

Terrain and Travel Advice

  • Avoid freshly wind-loaded features, especially near ridge crests, rollovers, and in steep terrain.
  • Seek out sheltered terrain where new snow hasn't been affected by wind.
  • Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.

Problems

Wind Slabs

An icon showing Wind Slabs

Watch for newly formed wind slabs on various aspects if you transition into wind-affected terrain. In steep areas where the snow has no slab properties use appropriate sluff management techniques.
