Avalanche warning for region Indre Sogn Tuesday 14.04.2020

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • Easy to trigger • 2 - Medium • Some steep slopes N, NE, E, SE, S above 800 masl • Over ca 800-900moh har vind fra nv fraktet snø inn i veldefinerte leområer og andre formasjonene som samler snø. Fokksnøen har varierende hardhet. Hard og bærende på utsatte steder mens myker når man beveger seg le. Lune skjerma formasjoner kan ha løsere snø.

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • Within half a meter • Very difficult to trigger • 3 - Large • N, NE, E, SE, S above 1200 masl • I høyfjellet finnes det kantkorn i dekke. Men hard bærende lag over gjør det svært vanskelig å løse ut. Men laget har evne til å forplante brudd.

Avalanche Problems

• Dry slab avalanche • Poor bonding between layers in wind deposited 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. • Easy to trigger • 1 - Small • Some steep slopes above 1000 masl

• 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 above 1000 masl
