Avalanche warning for region Heiane Sunday 12.03.2023

Avalanche Problems

• Wet slab avalanche • Buried weak layer of faceted snow near surface • Within half a meter • The weak layer collapses easily and clean (easy propagation). The collapsing weak layer is thin < 3 cm. The overlying slab is soft.

Avalanche Problems

• Buried weak layer of faceted snow beneath a crust • Within half a meter • The weak layer collapses easily and clean (easy propagation). A big and identifiable crystal in the weak layer.

Avalanche Problems

• Dry slab avalanche • Poor bonding between layers in wind deposited snow • Within half a meter • The weak layer collapses easily and clean (easy propagation). The collapsing weak layer is thin < 3 cm. The overlying slab is soft. • Difficult to trigger • 1 - Small • Some steep slopes E, SE, S above 600 masl

• Dry slab avalanche • Buried weak layer of faceted snow near surface • Within half a meter • The weak layer collapses easily and clean (easy propagation). The collapsing weak layer is thin < 3 cm. The overlying slab is soft. A big and identifiable crystal in the weak layer. • Difficult to trigger • above 600 masl • Det nedsnødde laget ligg over skare. Kor vanskeleg det er å løyse ut kjem an på tjukkelsen på laget under
