Avalanche warning for region Indre Troms Friday 12.03.2021

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 N, NE, E, W, NW above 500 masl

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow above a crust • The collapsing weak layer is thin < 3 cm. The overlying slab is soft. A big and identifiable crystal in the weak layer. • Difficult to trigger • 3 - Large • Some steep slopes N, NE, E, SE, S, SW, W, NW above 600 masl • Det er flere vedvarende svake lag i snødekket i denne delen av regionen. De svake lagene er vanskelig å påvirke, men kan påvirkes der snødekket er tynt og det kan gi store skred.

• 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 • 3 - Large • Few steep slopes N, NE, E, W, NW above 600 masl

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • Easy to trigger • 2 - Medium • Some steep slopes N, NE, W, NW above 300 masl

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within a meter • The weak layer collapses easily and clean (easy propagation). • Easy to trigger • Some steep slopes

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow near surface • Within a meter • The collapsing weak layer is thin < 3 cm. • Very difficult to trigger • SE, S between 700 masl and 600 masl • Fikk ikke utslag på ECT eller CT. Snøen er kun testet i S-SØ retning, problemet kan finnes flere steder.

• Dry slab avalanche • Poor bonding between layers in wind deposited snow • Within half a meter • The overlying slab is soft. • Difficult to trigger • 1 - Small • SE, S between 700 masl and 600 masl • Laget brøyt ut på slag nr. 13 på CT-testen. Kun testet snøen i S-SØ retning, problemet kan finnes flere steder.

• Dry slab avalanche • Buried weak layer of faceted snow above a crust • Within a meter • The collapsing weak layer is thin < 3 cm. • Difficult to trigger • 2 - Medium • Some steep slopes SE, S, SW between 700 masl and 500 masl • Dette er høyden og retning vi har sjekket. Utelukker ikke at problemet finnes i alle retninger og høyere opp. Antar at kantkorn ikke er stabilisert like mye i høyde over 700moh. Snøen under 500moh er mer homogen og stabil.

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within a meter • The weak layer collapses easily and clean (easy propagation). • Easy to trigger • Spesielt i lesider, rundt tregrensa.
