Avalanche warning for region Jotunheimen Friday 28.02.2020

Avalanche Problems

• Dry slab avalanche • Poor bonding between layers in wind deposited snow • Within half a meter • The overlying slab is soft. • Very difficult to trigger • 1 - Small • Some steep slopes NE, E between unknown masl and unknown masl • På nåværende tidspunkt er den ubundede fokksnøen høyt oppe i snødekke og laget er tynt. Store skred er usannsynlige. Dersom vinden transporterer nysnøen som har kommet nå til lesider vil vi ha et betydelig større skredproblem inntil lagene sintrer og stabiliseres.

Avalanche Problems

• Loose snow • S above 1900 masl

Avalanche Problems

• Dry slab avalanche • Poor bonding between layers in wind deposited snow • Within half a meter • Difficult to trigger • 2 - Medium • Few steep slopes E between 1400 masl and unknown masl

Avalanche Problems

• Poor bonding between layers in wind deposited snow • Within half a meter • The overlying slab is soft. • Difficult to trigger • 1 - Small • N, NE, E, W, NW between 1500 masl and unknown masl

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • The collapsing weak layer is thin < 3 cm. • Difficult to trigger • 2 - Medium • Many steep slopes N, NE, E, NW between 2500 masl and 1000 masl • Vanskelig å avgrense hvor lehengene er grunnet kraftig turbulente vindforhold

Avalanche Problems

• Loose snow • SE not between 1700 masl and 0 masl

Avalanche Problems

• Dry slab avalanche • The collapsing weak layer is thin < 3 cm. • Difficult to trigger • 3 - Large • Many steep slopes N, NE, E, SE between 2000 masl and 1200 masl

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow near the ground • Within a meter • The weak layer collapses easily and clean (easy propagation). A big and identifiable crystal in the weak layer. • Difficult to trigger • 2 - Medium • Some steep slopes N, NE, E, SE, S, SW, W, NW above 800 masl

• 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. • Difficult to trigger • 2 - Medium • Some steep slopes NE, E, SE, S above unknown masl
