Avalanche Activity

Forecast Snow Stability: Significant areas of unstable windslab will remain, particularly in gullies and around gully tops, above 1000 metres with North-West through North to East aspects most affected. Fragile cornices will be prone to collapse. Other aspects will be affected by cross loading. Below 1000 metres the snowpack will be moist and continue to slowly consolidate as the freezing level rises, with improving stability through the day. The avalanche hazard will be Considerable.

Snowpack Structure

Forecast Weather Influences: Mainly dry and cloudy through the period with only an occasional light snow shower. Overnight the freezing level will be around 1000 metres, rising only slightly during the day to just above this altitude. East-South-East winds will be moderate to fresh. Observed Weather Influences: Following a dry night it remained cloudy over the high summits with only isolated showers, falling as snow above 700 metres, during the morning. Winds were fresh to strong from Southerly directions with notable snow redistribution. ObservedSnowStability: Deposits of poorly bonded windslab have continued to build on the already significant accumulations from yesterday, mainly on North-West through North to East aspects above 900 metres. Cornices are fragile and prone to collapse, with collapsed debris witnessed during the morning. Other aspects are affected by cross loading. Below 900 metres the snowpack remains soft and moist with better stability. The avalanche hazard is Considerable.
