Avalanche warning for region Voss Friday 20.01.2023

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow above a crust • Within half a meter • 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 N, SW, W, NW between 1000 masl and 700 masl • Finner snev av begynnende kantkorn øverst i lag av MF dannet under mildværet forrige uke. Stor gradient høyt i snødekket. Skredproblemet utvikles videre i kulda, setter derfor dette som viktigste skredproblem i dag. Usikker på utbredelse, men antar at problemet er størst nær mildværsgrensa fra ons 11.jan.

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • The collapsing weak layer is thin < 3 cm. • Easy to trigger • 2 - Medium • Some steep slopes N, SW, W, NW above 800 masl • Fokksnøproblemet i den ferskeste nysnøen. Stort sett stabilisert, men gradienten høyt i snødekket svekker bindingene. Litt usikker på om dette problemet kan slås sammen med VVSL.

Avalanche Problems

• Dry slab avalanche • Poor bonding between crust and overlying snow • Within half a meter • The collapsing weak layer is thin < 3 cm. • Difficult to trigger • 2 - Medium • NE, E, W

Avalanche Problems

• 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. • Difficult to trigger • 1 - Small • Few steep slopes SE, S, SW, W, NW • finner nedføyket nysnø under både mye og harde men stort sett tynne flak i de himmelretninger jeg var i i dag. finner dem fra skoggrensen og oppover. har dessverre lite innsikt i nordvendt her. fokksnøen er vanskelig å løse ut. forventer kunn str 1

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • A big and identifiable crystal in the weak layer. • Very difficult to trigger • 1 - Small • Some steep slopes N, SW, W, NW above 500 masl • Vi fant nedføyket nysnø i to sjikt innad i den ferske fokksnøen. Glatt brudd, men dårlig bruddforplantning. Heller ikke faretegn fra snødekket observert idag mellom ca. 600 m o.h, og 1200 m o.h.
