Kernpunkte

Carefully evaluate steep slopes - this is where you'll trigger an avalanche after the storm, particularly in wind-affected terrain.

    Shifting wind directions have created fresh wind slabs on a variety of aspects.

    Where they exist, cornices pose a significant hazard and should be avoided.

Confidence

Moderate - Timing or intensity of solar radiation is uncertain on Sunday

Weather Forecast

Friday: Flurries. Freezing level around 1500 m. Winds 10-20 km/h from the southwest. Saturday: Flurries, clearing in the afternoon. Freezing level around 1500 m. Winds mostly calm. Sunday: Dry, with sunshine, especially in the morning. Freezing level rising to 1900 m. Light winds.

Avalanche Summary

Natural and skier-triggered avalanches up to size 2.5 were reported during the storm on northerly aspects above 1800 m.

Snowpack Summary

15-25 cm of new snow with moderate to strong winds from a variety of directions have created fresh wind slabs in exposed terrain at treeline and above. Numerous crusts exist in the upper snowpack, especially on solar aspects. Cornices are large and remain a concern: Saturday's fatal accident near Lions Bay illustrates the danger of them breaking off, and the large avalanches they can trigger. Expect small loose dry avalanches in steep terrain where the new snow is sitting on a crust.
