Avalanche warning for region Hardanger Friday 15.01.2021

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 • 3 - Large • Some steep slopes NE, E, SE, S above 700 masl • Fokksnøflak over kantkorn, muligens omdannet overflaterim. Størst tilstedeværelse av problemet på vei opp til toppene men ikke på selve topp-punktene som er svært avblåst og nesten rensket for snø.

• Dry slab avalanche • Buried weak layer of faceted snow near surface • 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 • Some steep slopes NE, E, SE, S above 700 masl • Kanskje nedføyka nysnø som er i ferd med å bli overflatenære fasetter. Det er disse som sprekker og deler seg rundt skiene flere steder.

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • The overlying slab is soft. A big and identifiable crystal in the weak layer. • Very easy to trigger • 3 - Large • Many steep slopes N, NE, E, SE, S above 600 masl

• 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. • Easy to trigger • 3 - Large • Many steep slopes N, NE, E, SE, S above 600 masl

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 overlying slab is soft. A big and identifiable crystal in the weak layer. • Very easy to trigger • 2 - Medium • Some steep slopes N, NE, E, W, NW above 600 masl • Merker ut dei sektorane eg har vore i.

• Dry slab avalanche • Buried weak layer of surface hoar • Within a meter • The weak layer collapses easily and clean (easy propagation). A big and identifiable crystal in the weak layer. • Easy to trigger • 3 - Large • Some steep slopes N, NE, E, SE, W, NW above 700 masl • Relativt komplekse forhold. Enkelte plasser er det mykje nysnø under rimelig og mykje energi forsvinn i det, medan andre plasser er det tynnare.
