Avalanche warning for region Indre Fjordane Thursday 16.03.2023

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • Spontaneous release • 2 - Medium • Some steep slopes N, NE, SW, W, NW above 800 masl

• Dry slab avalanche • Buried weak layer of faceted snow above a crust • Within a meter • Spontaneous release • 3 - Large • Some steep slopes N, NE, SW, W, NW above 800 masl

• Dry slab avalanche • Buried weak layer of surface hoar • Within a meter • Spontaneous release • 2 - Medium • Few steep slopes N, NE, SW, W, NW above 800 masl • Tror feltene er små og få.

• Loose wet avalanche • Loose snow • Spontaneous release • 1 - Small • Some steep slopes S, SW • Rutsjer fra berg i vindbeskyttede solheng.

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • Easy to trigger

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow near surface • Within half a meter • A big and identifiable crystal in the weak layer. • Easy to trigger • 3 - Large • Few steep slopes N, NE, E, SE, S, SW, W, NW above 700 masl • Vi antar at kantkorn i snødekket kan være et problem i alle høyder over 700 moh

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow near surface • Within half a meter • The collapsing weak layer is thin < 3 cm. The overlying slab is soft. A big and identifiable crystal in the weak layer. • Easy to trigger • 3 - Large • Some steep slopes N, NE, E, SE, S, SW, W, NW above 600 masl

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • The overlying slab is soft. • Easy to trigger • 2 - Medium • Few steep slopes E, SE, S, SW, W above 800 masl

Avalanche Problems

• Dry slab avalanche • Poor bonding between layers in wind deposited snow • Within half a meter • The collapsing weak layer is thin < 3 cm. The overlying slab is soft. • Difficult to trigger • 2 - Medium • Few steep slopes N, NE, E, SE, S, SW, W, NW above 700 masl

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • Within half a meter • The collapsing weak layer is thin < 3 cm. • Difficult to trigger • 3 - Large • Few steep slopes N, NE, E, SE, S, SW, W, NW above unknown masl

Avalanche Problems

• 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. The overlying slab is soft. A big and identifiable crystal in the weak layer. • Easy to trigger • below 800 masl • Både binding mot skarelag og innad fokksnø virker å vere problemet. Stor variasjon mtp kvar snøen har lagt seg og korleis vinden har virka. Den mest potente observasjonen i dag var i mer skjerma terreng rett over skoggrensa.
