Recently formed wind slabs in alpine features remain our main concern.

Early Season Conditions persist, so travel with caution.

Snowpack Summary

The snowpack is still generally very shallow with only 25-40cm at treeline. The alpine is heavily wind effected, with scoured windward slopes and ridges, and deposits up to a meter deep suspected in leeward features.

Avalanche Problems

Wind Slabs

Snow and wind loading with gusting winds created a wind slab hazard. The team has limited snowpack observations yet tests show the base is weak and the new snow interface is uncertain. Remain vigilant for reactive and changing conditions.

Aspects: North, North East, East, South East, West, North West.

Elevations: Alpine.

Likelihood: Possible

Expected Size: 1 - 2
