Snowpack
Snowpack Description:
Southerly winds were strong enough for transport although very little loading was happening except cornice formation. Most slabs that were forming seemed well adhered to the snow surface with the warm temperatures. Previous west and northwest winds built fresh, tender cornice above southeast facing slopes in West Willow. Winds seemed to help keep loose wet instabilities at the surface moderated today.
Avalanches
Avalanche Description:
A recently formed, large chunk of cornice overhanging a southeast-facing slope broke off, forcing a small slab (30 cm deep by 10 meters) out directly below the cornice.
