In sintesi

Variable hard surfaces and low danger give way to a lingering wind slab problem in the region's highest elevations.

    Northerly outflow wind has formed small wind slabs on some alpine features.

Confidence

High

Avalanche Summary

No recent avalanches have been observed in the North Shore mountains.

A small (size 1) wind slab was triggered by a skier near Powell River on Wednesday (see photo). Because of the weak grains wind slabs have formed over, this type of reactivity is expected to persist.

Snowpack Summary

A surface crust exists to the top of the North Shore mountains. Higher elevations in other parts of the region have widespread wind-affected surfaces and more limited wind slab distribution over the same crust.

Conditions remain rugged at lower elevations.

Terrain and Travel Advice

  • Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
  • A crust on the surface will help bind the snow together, but may make for tough travel conditions.
