Snowpack Summary

Between 10 and 30 cm of low-density faceted snow sits on old hard surfaces including wind-affected snow and melt-freeze crusts. The low-density snow may sluff easily on these hard surfaces. Thin wind slabs may be found in the alpine. Moist snow may be found on steep south aspects when the sun is out.The lower snowpack is strong and settled.

Avalanche Problems

Wind Slabs

Small pockets of wind slabs may exist from recent strong winds.

Be careful with wind loaded pockets, especially near ridge crests and roll-overs.

Aspects: All aspects.

Elevations: Alpine.

Likelihood: Possible

Expected Size: 1 - 1.5
