Use extra caution in the alpine where rider triggerable wind slabs could still be found.
On the North Shore a diminishing snowpack will make for challenging travel.

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 the potential for wind slab over facets. The snow surface will likely become moist throughout the day.
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.
- Back off slopes as the surface becomes moist or wet with rising temperatures.
