Continue to assess the bond between new snow and the underlying crust. Wind slabs could be larger and more reactive if a poor bond is found.

Avalanche Summary
On thursday our field team was able to ski cut small wind slabs just below ridge crests.
Snowpack Summary
15 to 50cm of recent snow has fallen on a crust that likely extends to mountain tops on all aspects. Southwest winds have likely blown this new snow into wind slabs on north and east aspects in the alpine and scoured or pressed windward slopes..
The remainder of the snowpack is consolidated and strong.

Terrain and Travel Advice
- Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
- Closely monitor how the new snow is bonding to the crust.
- Recent wind has varied in direction so watch for wind slabs on all aspects.
