Avalanche warning for region Voss Saturday 10.03.2018

Avalanche Problems

• Dry 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 collapsing weak layer is thin < 3 cm. The overlying slab is soft. A big and identifiable crystal in the weak layer. • Easy to trigger • Likely • 1 - Small • Few steep slopes SE, S, SW above 700 masl • Solskare i SV, S, SØ i brattheng med terrenghelning over 22 grader. Kantkorn og begerkrystaller (opptil 5 mm) er godt utviklet over solskaren og det bryter lett og glatt. Overliggende lag er myke og derfor vurdert til å dannne kun små/harmløse skred - vær obs der flakene er tykkere og/eller hardere.

• Dry slab avalanche • Buried weak layer of faceted snow above a crust • Over one meter • The collapsing weak layer is thin < 3 cm. A big and identifiable crystal in the weak layer. • Difficult to trigger • Unlikely • 3 - Large • Most steep slopes N, NE, E, SE, S, SW, W, NW below 900 masl • Fasettlag som trolig stammer fra mildværet som gikk opp til 900-1000 i slutten av januar.

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within half 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 • Possible • 1 - Small • Some steep slopes N, W, NW above 800 masl • Mulig flakdannelse lavere i terrenget pga kortvarig temperaturstigning i går ettermiddag. Flaking pga temperatur vil være i alle himmelretninger.

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow near surface • Within half a meter • The collapsing weak layer is thin < 3 cm. The overlying slab is soft. • Easy to trigger • Possible • 2 - Medium • Many steep slopes N, S, SW, W, NW above 0 masl • Stabilitetstester gir Q1 brudd ved liten tb.

The overlying slab is soft. A big and identifiable crystal in the weak layer. • Easy to trigger • Possible • 2 - Medium • Some steep slopes N, NE, SW, W, NW above 500 masl • Kankorn kan ligge i alle himmelretninger, men rosens skravering er der fokksnøen over kantkornene er mest fremtredende
