Avalanche Activity

LO for 15/2. Localised fresh unstable windslab mainly on NW-N-E aspects above 900m. Cornices! Old snowpack stable. Moderate hazard.

Forecast Snow Stability: Localised accumulations of unstable windslab will develop during the day mainly on North-West through North to East aspects above 900 metres. Features such as gullies, corrie rims and ridge flanks will be particularly affected. Fragile cornices will form above these aspects. The older snowpack will be firm and stable. The avalanche hazard will be Moderate.

Snowpack Structure

Forecast Weather Influences: After a mainly dry night precipitation during the day will fall as snow above around 800 metres. Southerly gales overnight veer and ease to become strong South-Westerlies during the day. Freezing level dropping from above the summits to around 900 metres during the day. Observed Weather Influences: Around dawn the freezing level rose above the summits. There was some light rain and strong South-South-Westerly winds.
