Avalanche warning for region Jotunheimen Sunday 14.02.2021

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow near surface • The collapsing weak layer is thin < 3 cm. • Difficult to trigger • 2 - Medium • Some steep slopes N, NE, E, SE, S, SW, W, NW above 1300 masl

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. • Difficult to trigger • 2 - Medium • Many steep slopes N, NE, E, SE, S, SW, W, NW

Avalanche Problems

• Dry slab avalanche • Buried weak layer of surface hoar • 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 • 1 - Small • Few steep slopes N, W, NW above 900 masl • I isolerte søkk og forsenkninger etter SØ vind sist helg, og for det meste tynne flak.

Tynne lag vindpakket snø som ligger på overflaterim og kantkorn. Andre steder i området her er det også et djupere nedsnødd kantkornlag, som beskrevet i tidligere observasjoner, f.eks. sist helg. Det laget er vanskelig å løse ut, men har større skadepotensiale.
