Avalanche warning for region Hallingdal Sunday 10.04.2022

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. A big and identifiable crystal in the weak layer. • Easy to trigger • 2 - Medium • Few steep slopes N, NE, E, SE above 900 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. • Easy to trigger • 1 - Small • Few steep slopes E, SE, S above 800 masl • Små lommer med fersk fokksnø ligger på overflate kant. Lite snø og hente, så det blir begrenset størrelse på eventuelle skred.

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • The overlying slab is soft. A big and identifiable crystal in the weak layer. • Easy to trigger • 1 - Small • Few steep slopes NE, E, SE, S above 900 masl • Liten utbredelse selv med denne begrensningen i sektor.

• Dry slab avalanche • Buried weak layer of faceted snow above a crust • 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 • 1 - Small • Few steep slopes NE, E, SE, S above 900 masl • Samme utbredelse som nedføyka nysnø, men dette sp gikk ikke like lett til brudd. Ingen av skredproblemene viste god forplantningsevne ved undersøkelser.
