Avalanche warning for region Voss Saturday 25.03.2023

Avalanche Problems

• 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. • Easy to trigger • 2 - Medium • Few steep slopes N, NE, E, SE, S, SW, W, NW above 900 masl • Milde tempraturer gjør at dette skredproblemet vil stabilisere seg relativt raskt

• 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 • 3 - Large • Few steep slopes N, NE, E, SE, S, SW, W, NW above 900 masl • Dette er fortsatt et tilstedeværende skredproblem i høyden.

Avalanche Problems

• Dry slab avalanche • Poor bonding between crust and overlying snow • Within a meter • The collapsing weak layer is thin < 3 cm. The overlying slab is soft. • Easy to trigger • 2 - Medium • Few steep slopes N, NE, E above 1000 masl • Nedføyka laussnø over skare. Varierande hardheit over, men ikkje observert særleg harde vindpåverka flak i dette området

• Loose wet avalanche • Loose snow • Spontaneous release • 2 - Medium • Some steep slopes SE, S, SW, W between 1200 masl and 700 masl • I hovudsak der soøa tek

Avalanche Problems

• Wet slab avalanche • Buried weak layer of faceted snow above a crust • Within half a meter • The weak layer collapses easily and clean (easy propagation). The overlying slab is soft. • Difficult to trigger • 2 - Medium • Many steep slopes N, NE, E, SE, S, SW, W, NW above 800 masl • Kantkornlaget finnes fortsatt (såvidt) på ca. 900 m o.h. sørvendt. Da må vi gå utfra alle eksposisjoner over denne høyden.

• Loose wet avalanche • Loose snow • Spontaneous release • 1 - Small • Few steep slopes SE, S, SW, W above 400 masl

• Dry slab avalanche • Buried weak layer of new snow • The weak layer collapses easily and clean (easy propagation). • Difficult to trigger • 2 - Medium • Some steep slopes N, NE, E, W, NW above 1000 masl • Dette skredproblemet er ikke tilstede her jeg er i dag på grunn av lav høyde, men må jo eksistere i høyfjellet med de siste dagers snøfall.

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 • 2 - Medium • Some steep slopes N, NE, NW above 1100 masl • Gjorde en spadeprøve på fokksnøflaket da ect ikke avdekker like godt dårlige bindinger i fokksnøen
