Forecast Snow Stability: Fresh unstable windslab will be deposited in wind sheltered areas. Greatest accumulations will be on West through North to North-East aspects above 900 metres. East aspects will also be affected. Fragile cornices will build above these aspects. The old snowpack will continue to consolidate and be generally stable. The avalanche hazard will be Considerable.
