Forecast Snow Stability: Fresh unstable windslab will continue to develop. Greatest accumulations will be on West through North to East aspects above 900 metres. Fragile cornices will form above these aspects. The older snowpack will remain generally stable. The avalanche hazard will be Moderate.

Snowpack Structure

Forecast Weather Influences: Showers throughout the period falling as snow above around 600 metres. Fresh to strong winds, Southerly initially, slowly veering to become Westerly in the afternoon.
