Avalanche warning for region Sunnmøre Wednesday 04.01.2023

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • The overlying slab is soft. A big and identifiable crystal in the weak layer. • Easy to trigger • 2 - Medium • Some steep slopes S, SW, W, NW 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. • Difficult to trigger • 3 - Large • Few steep slopes S, SW, W, NW between 1000 masl and 600 masl • Usikker. Men me har minst eit ferskt skred på det. No gjekk det som eit stort str 1 i eit heng som har produsert str 3 før. Så kanskje Max str 2 er riktig. Avhengig av flakstr og hengstr. Pluss dei andre faktorane som må til.

Avalanche Problems

• Dry slab avalanche • Poor bonding between layers in wind deposited snow • Within half a meter • Difficult to trigger • 2 - Medium • Few steep slopes N, W, NW above 600 masl

• Dry slab avalanche • Poor bonding between crust and overlying snow • Within half a meter • The weak layer collapses easily and clean (easy propagation). The collapsing weak layer is thin < 3 cm. • Very difficult to trigger • 2 - Medium • Few steep slopes N, W, NW above 600 masl

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • The overlying slab is soft. A big and identifiable crystal in the weak layer. • Easy to trigger • 1 - Small • Few steep slopes N, NE, E, SE, S, SW, W, NW above 800 masl • Vinden jobbar rolig nesten alle aspekt.
