TO for 16.2 Unstable windslab on West through North to South-East aspects above 700m in steep wind sheltered areas. Moderate Hazard.
Forecast Snow Stability: Instabilities will persist within existing unstable windslab on North through East to South-East aspects above 700 metres. Terrain most affected will be crag aprons, corrie rims and gully tops. Isolated pockets of fresh unstable windslab will build above 700 metres on West to North aspects, in similar wind sheltered locations. Wind exposed slopes will be mostly scoured. The older snowpack will be stable throughout. The avalanche hazard will be Moderate.
