Avalanche warning for region Hallingdal Friday 04.03.2022

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • The overlying slab is soft. A big and identifiable crystal in the weak layer. • Easy to trigger • 2 - Medium • Some steep slopes NE, E, SE above unknown masl

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • A big and identifiable crystal in the weak layer. • Very difficult to trigger • 3 - Large • N, NE, E, SE, S, SW, W, NW above unknown masl

Avalanche Problems

• Dry slab avalanche • Poor bonding between layers in wind deposited snow • The collapsing weak layer is thin < 3 cm. • Difficult to trigger • 2 - Medium • Some steep slopes NE, E, SE, S above 800 masl • Fokksnøen virker generelt bra stabil. Enkelte ferske fokksnøflak etter vind i går kan være lette å løse ut men da neppe skred større enn str1.

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. A big and identifiable crystal in the weak layer. • Difficult to trigger • 3 - Large • Few steep slopes N, NE, E, SE above 1100 masl • Krystallene er like i overkant av 1 mm

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • The overlying slab is soft. • Easy to trigger • 1 - Small • Some steep slopes NE, E, SE above 1000 masl • Mindre ansamlinger av fersk fokksnø. Begrenset mengde fokksnø og mildvær gjør at omfanget er lite og stabilisering skjer raskt. Skredstr kan kanskje bli str 2, enkelte steder.
