Avalanche Forecast
Regions: Sea To Sky.
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.
