Spring time conditions exist. Good skiing can still be found on north and east aspects.

    Wind slabs and wind effect can be found in the alpine. Wind slabs are unlikely to release naturally but can be triggered by skiers and climbers.

  • Persistent Slabs

    Concern still exists for last weeks storm snow (20-30 cm) where it overlies a crust on solar aspects. Some recent avalanches have been observed on this interface.

Weather Forecast

Friday will bring unsettled conditions with scattered flurries (up to 10 cm at treeline along the divide) and freezing levels around 1500 m. The weekend will bring mixed sun and cloud and cooler temperatures (freezing levels around 1100 m).

Snowpack Summary

Variable surface conditions with dry snow present on polar aspects above 1600 m and temp crusts to ridgetops on solar aspects. Small wind slabs found in the high alpine. Concern still exists for last weeks storm snow where it sits on a buried suncrust (down 20-30 cm) on south and west aspects. Shallow snowpack areas are also still a concern.

Avalanche Summary

No new avalanches observed or reported in last 24 hours.
