Avalanche warning for region Indre Fjordane Tuesday 14.03.2023

Avalanche Problems

• 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. • Difficult to trigger • 2 - Medium • Few steep slopes N, NE, E, SE, S, SW, W, NW above 700 masl

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • Within half a meter • The collapsing weak layer is thin < 3 cm. • Difficult to trigger • 3 - Large • Few steep slopes N, NE, E, SE, S, SW, W, NW above unknown masl

Avalanche Problems

• Dry slab avalanche • Poor bonding between crust and overlying 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. A big and identifiable crystal in the weak layer. • Easy to trigger • below 800 masl • Både binding mot skarelag og innad fokksnø virker å vere problemet. Stor variasjon mtp kvar snøen har lagt seg og korleis vinden har virka. Den mest potente observasjonen i dag var i mer skjerma terreng rett over skoggrensa.

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 • 2 - Medium • Few steep slopes N, NE, E, SE, S, SW, W, NW above 600 masl

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • The weak layer collapses easily and clean (easy propagation). The overlying slab is soft. • Easy to trigger • 2 - Medium • Some steep slopes NE, E, SE, S, SW, W above 600 masl

A big and identifiable crystal in the weak layer. • Easy to trigger • 3 - Large • Few steep slopes N, NE, NW above 700 masl • Vi fant skarelaget med svake lag både over og under i nordvendt og sørvendt. Vanskelig å påvirke i sørvendt. Mest potent mot nord

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • Difficult to trigger • 2 - Medium • Few steep slopes N, NE, E, SE, S, SW, W, NW above 1000 masl

Men pågåande vindtransport kan danne ustabile nysnøflak som kan være lette å løyse ut. Forventa str 1, maks 2 utifrå at det virkar som fokksnøen har lita evne til å binde seg til flak og dermed også lita evne til bruddforplantning
