Moderate

Avalanche Summary

No significant avalanches were reported on Tuesday. We suspect that rider triggerable wind slabs could still be found.

Snowpack Summary

Previous storm snow accompanied by southerly winds has likely formed wind slabs on west through east aspects at upper elevations. Up to 5 cm of new snow can be found above a crust in sheltered terrain above 1200 m. Below this elevation a thick melt-freeze crust will be found on the surface on all aspects.

A crust from late March can be found down 50 to 80 cm on all solar aspects and at treeline and below on north-facing terrain. Below this crust, the snowpack is generally well-settled.
