Avalanche warning for region Lyngen Tuesday 16.02.2021

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow near surface • Within 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 above 100 masl • Plus sannsynligvis leområder i andre himmelretninger. Over og/eller under skare.

• Dry slab avalanche • Poor bonding between layers in wind deposited snow • Within 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 above 300 masl • Etter siste dagers vind fra sør og vest. Men også andre leheng. Svage lag kan gi forplanting fra tynne till tykke områder å gi store og svært store skred på mange plasser.

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 • N, NE, E, SE, S, SW, W, NW above 400 masl

• Dry slab avalanche • Poor bonding between layers in wind deposited snow • Within half a meter • The collapsing weak layer is thin < 3 cm. The overlying slab is soft. • Easy to trigger • 1 - Small • N, NE, E

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. • Difficult to trigger • 3 - Large • Some steep slopes N, NE, E, SE, S, SW, W, NW • Har vært skifte ende vindretninger så nå er det flak i det fleste hengene. Får ingen fare tegn på dette laget men man må anta at det er tilstede frem til det motsatte er bevist

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • Over one meter • The collapsing weak layer is thin < 3 cm. A big and identifiable crystal in the weak layer. • Easy to trigger • 3 - Large • Some steep slopes

• Dry slab avalanche • Poor bonding between layers in wind deposited snow • Within half a meter • The overlying slab is soft. • Easy to trigger • 2 - Medium • Some steep slopes above 300 masl • Bundet seg bedre over skogen

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). The collapsing weak layer is thin < 3 cm. The overlying slab is soft. • Easy to trigger • 1 - Small • Some steep slopes N, NE, E, SE, S, SW, NW between 1000 masl and 400 masl • Snøtrsmsport I flere himmelretninger.

• Dry slab avalanche • Buried weak layer of faceted snow above a crust • Within 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. • Very easy to trigger • 2 - Medium • Many steep slopes N, NE, E, SE, S, SW, W, NW between 1000 masl and 400 masl • Trigger ikke så lett på CT, men er svært potent. Kan fjerutløses, eller trigges der snødekket er tynt. Utbredt problem som kan gi farlig størrelse på skred.
