Avalanche Activity

Forecast Snow Stability: Fresh unstable windslab will develop through the period mainly on South-West through West to North aspects above 1000 metres with more localised deposits at lower elevations. Fragile cornices will develop above these aspects. Stability in the older snowpack will generally be good. The avalanche hazard will be Considerable.

Snowpack Structure
