Regions: Glacier.

Moderate avalanche hazard means human-triggered avalanches are possible. Winds slabs and a buried sun crust require thoughtful decision making.

Weather Forecast

A mix of sun and cloud as a weather system moves out of the area. No significant precipitation is expected. Moderate northerly winds will calm this morning and back to the SE. Freezing levels climb to 1100m. A light snowfall begins early Saturday morning with up to 6cm. Temperatures drop on Sunday with the arrival of a cold front and trace precip.

Snowpack Summary

35cm of settling storm snow now buries a facet layer. Height of snow at 1900m is 330cm. Moderate winds have created wind slabs that can be found on all aspects above tree line. A crust is down 30-50cm on solar aspects and the mid January persistent weak layers are buried 150-200cm.

Avalanche Summary

No new natural avalanches observed.

Avalanche Problems

Wind Slabs

Moderate winds have created pockets of wind slab in the alpine and exposed areas at tree line. In the alpine, the wind slab is poorly bonded to buried facets and a crust on solar aspects. Due to shifting winds, slabs can be found on all aspects.

Be cautious as you transition into wind affected terrain.Use caution in lee areas. Recent wind loading has created wind slabs.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 2.5
