Avalanche warning for region Lyngen Saturday 15.02.2020

Avalanche Problems

• Dry slab avalanche • Poor bonding between crust and overlying snow • 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 • 1 - Small • Few steep slopes NE, E, SE, S above 1000 masl

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • A big and identifiable crystal in the weak layer. • Difficult to trigger • W

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 • N, NE, E, SE above unknown masl

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • The overlying slab is soft. • Easy to trigger • 2 - Medium • Some steep slopes NE, E, SE, S above 300 masl • Endel snø siste døgnet og vindpålagring fra øst har skapt myke flak mange steder, men ettersom flakene er så myke er det lite tegn til propagering og bruddforplantning. Det er observert endel ferske skred str 1-2. i Breivikseidet som nok har gått i dette laget.

• Dry slab avalanche • Buried weak layer of faceted snow beneath 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, S, SW, W, NW above 300 masl • LBT ga brudd i kantkornlag under det eldste skarelaget, som besto av kant og noe MF krystaller, ved stor belastning. Der vi grov var det relativt lite snø, og selv der var det vanskelig å påvirke dette laget. Men det er tilstede med tydelige kantkorn.
