Forecast Snow Stability: New unstable windslab will continue to be deposited in wind sheltered areas throughout the period. Greatest accumulations will be on North to East aspects above 900 metres. South-East aspects will also be affected. Cornices will build above all these aspects. Below 900 metres windslab will also be deposited on North to East aspects. The avalanche hazard will be Considerable.
Forecast Weather Influences: Winds will be West-South-Westerly, storm force overnight easing to gale force during the day. This evening a period of heavy snowfall is expected, then from midnight snow showers for the rest of the period above around 400 metres. The freezing level will be around 500 metres.
