Avalanche warning for region Indre Troms Thursday 15.02.2018

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • Within half a meter • The overlying slab is soft. A big and identifiable crystal in the weak layer. • Easy to trigger • Unlikely • 1 - Small • Few steep slopes N, NE, E, SE, S, SW, W, NW above 300 masl • Begerkrystall under skare nær overflaten

Avalanche Problems

• Buried weak layer of faceted snow beneath a crust • Within half a meter • A big and identifiable crystal in the weak layer.

Avalanche Problems

• Dry slab avalanche • Buried weak layer of surface hoar • 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 • Unlikely • 1 - Small • Few steep slopes SE between 500 masl and 400 masl • Nedføyket overflaterimlag på 15 cm.

Avalanche Problems

• Dry slab avalanche • Buried weak layer of surface hoar • Within half a meter • The collapsing weak layer is thin < 3 cm. • Difficult to trigger • Unlikely • 1 - Small • Some steep slopes N, NE, E, W, NW between 500 masl and 0 masl • Det svake laget er godt beskyttet av hardpakket lag over.

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • Within half a meter • Easy to trigger • Possible • 1 - Small • Some steep slopes N between 500 masl and 0 masl • Verdt å følge med på. Hvis vi får ett snøfall med påfølgende vindtransport vil sannsynligheten for skred og skredstørrelsen øke i dette området.

Avalanche Problems

• Dry slab avalanche • Poor bonding between layers in wind deposited snow • Within half a meter • The weak layer collapses easily and clean (easy propagation). A big and identifiable crystal in the weak layer. • Difficult to trigger • Unlikely • 1 - Small • Few steep slopes SW, W, NW between 500 masl and 0 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). A big and identifiable crystal in the weak layer. • Easy to trigger • Likely • 1 - Small • Few steep slopes NW between 600 masl and 500 masl

• Dry slab avalanche • Buried weak layer of faceted snow near the ground • Within half a meter • A big and identifiable crystal in the weak layer. • Difficult to trigger • Unlikely • 2 - Medium • NW between 600 masl and 500 masl
