Avalanche warning for region Tromsø Thursday 29.12.2022

Avalanche Problems

• Dry slab avalanche • A big and identifiable crystal in the weak layer. • Difficult to trigger • 3 - Large • Many steep slopes N, NE, E, SE, S, SW, W, NW • Kun vært opp til 500moh, men vil anta utbredelsen fortsetter i høyden.

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

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow above a crust • Within 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 • Mørketid og min første obs. i høyden, så vanskelig å vite omfang i regionen ellers, men der har varsom fin beskrivelse. VVSL betyr jo gjerne at alle himmelretninger er aktuell, men størst skredstørrelse mulug i leheng mot nord etter mykje S-vind.

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow above a crust • Within 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 • 2 - Medium • Some steep slopes N, NE, E, SE, S, SW, W, NW above 300 masl

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • Within a meter • The collapsing weak layer is thin < 3 cm. 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 300 masl • Generelt vanskelig å trigge da det er under skare/is og generelt relativt dypt i snødekket

• Dry slab avalanche • Buried weak layer of new 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. • Very easy to trigger • 2 - Medium • Some steep slopes N, NE, SW, W, NW above 300 masl

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow near the ground • Within half a meter • The weak layer collapses easily and clean (easy propagation). The overlying slab is soft. A big and identifiable crystal in the weak layer. • Easy to trigger • 2 - Medium • Many steep slopes N, NE, E, SE, S, SW, W, NW above 200 masl

• Dry slab avalanche • Buried weak layer of new snow • The weak layer collapses easily and clean (easy propagation). The collapsing weak layer is thin < 3 cm. The overlying slab is soft. • Easy to trigger • 2 - Medium • N, NE, E, SE, S, SW, W, NW above 300 masl
