Avalanche warning for region Vest-Telemark Tuesday 21.03.2023

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • Difficult to trigger • 2 - Medium • Some steep slopes N, NE, E, SE, S, SW, W, NW above 1000 masl

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • The weak layer collapses easily and clean (easy propagation). • Easy to trigger • 1 - Small • Some steep slopes N, NE, E, SE, S, SW, W, NW above 900 masl

• Dry slab avalanche • Buried weak layer of faceted snow near the ground • Over one meter • A big and identifiable crystal in the weak layer. • Very difficult to trigger • 3 - Large • Some steep slopes N, NE, E, SE, S, SW, W, NW above 900 masl

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • Easy to trigger • 1 - Small • Some steep slopes N, NE, E, SE, S, SW, W, NW above 900 masl • Vi fikk brudd på nedføyket nysnø når vi tok LBT. Laget er høyt i snødekket og derfor forventes eventuelle skred til å være små.

• Dry slab avalanche • Buried weak layer of faceted snow near the ground • Within a meter • A big and identifiable crystal in the weak layer. • Difficult to trigger • 3 - Large • Few steep slopes N, NE, E, SE, S, SW, W, NW above 900 masl

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • Within half a meter • A big and identifiable crystal in the weak layer. • Difficult to trigger • 2 - Medium • Some steep slopes N, NE, E, SE, S, SW, W, NW above 900 masl

• Dry slab avalanche • Buried weak layer of faceted snow near the ground • Within a meter • A big and identifiable crystal in the weak layer. • Very difficult to trigger • 3 - Large • Some steep slopes N, NE, E, SE, S, SW, W, NW above 800 masl

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • Within half a meter • Difficult to trigger • 2 - Medium • Few steep slopes N, NE, E, SE, S, SW, W, NW above 1000 masl

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • Within half a meter • A big and identifiable crystal in the weak layer. • Difficult to trigger • 3 - Large • Some steep slopes N, NE, E, SE, S, SW, W, NW above 1000 masl • Der vi testet var det svært vanskelig å løse ut, men der snødekket er tynt kan det være noe lettere.

• Loose wet avalanche • Loose snow • Spontaneous release • 1 - Small • Some steep slopes SE, S, SW, W below 900 masl • Sola varmet godt i dag og i de lavereliggende delene av regionen kunne det nok gå noen små fuktige/våte skred.

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • Within half a meter • Difficult to trigger • 3 - Large • Few steep slopes N, NE, E, SE, S, SW, W, NW above 1000 masl • Fant et lag med VVSL med kantkorn/beger under skarelag. Var vanskelig å påvirke på denne plassen, men tenker at der det er tynnere snødekke over skarelaget, så kan det være mulig å påvirke.

Avalanche Problems

• Wet slab avalanche • Buried weak layer of faceted snow near surface • Within half a meter • The collapsing weak layer is thin < 3 cm. • Very easy to trigger • 3 - Large • Many steep slopes N, NE, SE, S, SW, W, NW above 600 masl • Kantorn er fremdeles godt bevart under snødekket. Første 20-30cm er noe våte, så er det tørr snø under før skarelag og kantorn. Lett å løse ut noe nå med liten tileggsbelstnig i sider hvor sola ikke har tatt
