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

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.

- A crust on the surface will help bind the snow together, but may make for tough travel conditions.
