Avalanche Activity

Forecast Snow Stability: Unstable windslab will persist mainly on North to East aspects above 900 metres.

Recently formed cornices will be fragile. The avalanche hazard will be Considerable.

Snowpack Structure

Forecast Weather Influences: Strong North-Westerly winds in the evening veer to the North-North-East and then ease during the day. Snow showers in the evening followed by a dry day.
