Highest danger level per day:

Avoid lee areas with wind deposited snow, typically behind ridges, ribs and in gullies. Especially where the wind deposited slabs are thin or soft, a slab avalanche is easier to trigger here. Even small avalanches can cause large consequences.

Avalanche Activity

25. Jan. During the day No avalanche activity

Weather

No precipitation -11 °C 4 m/s from E ← 5% clouds

Avalanche Danger Assessment

1 Low Snødekket består av store flater med hard skare. Fokksnøen ligger ujevnt fordelt over dette, og er mange plasser steinhard. Fokksnøen viste liten/ingen evne til forplantning. Til tross for kantkorn i snødekket, så fremstår snødekket som porøst og uten evne til forplantning. Videreutvikling av kantkorn. Forecast too high

Danger Sign

No signs observed

Avalanche Problems

Dry slab avalanche Poor bonding between crust and overlying snow Within half a meter Difficult to trigger 1 - Small N, W, NW above 500 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). A big and identifiable crystal in the weak layer. Difficult to trigger 1 - Small N, NE, E, SE, S, SW, W, NW above 600 masl

Tests

LBT@3cmQ1 Middels+ belastning.

Snow Cover

No snowdrift 0 cm new snow Crust Dry Svært lite snø i regionen, med mest i øst. Snødekket er preget av kaldt og klart vær. Fokksnø i lesider på 300moh, men hyppigere og større områder med fokksnø over skare fra 500moh. En del plasser er fokksnøen svært hard (P/K). Overflaterim og tilsynelatende nedføyket overflaterim observert fra 500moh (størrelse 2mm) og til toppen (størrelse 6mm). Kantkorn er nå mer velutviklet halvveis ned i snødekket. Stabilitetstest viser god binding i snødekket. Ingen skytende sprekker.

Danger Sign

Avalanche Problems

Dry slab avalanche Buried weak layer of new 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 1 - Small N, S, SW, W, NW above 400 masl Veldig begrenset lokal utbredelse. I områder det har vært vind. Begynnende kantkrondannelse i under fokksnøflakene.

Snow Cover

15 cm in total No snowdrift 0 cm new snow Snow line at 5 masl Surface hoar on a hard surface Dry Generelt veldig lite snø. Varierende snøoverflate; fra dominerende nesten snøfritt til tynt skarelag i lavere områder; høyere opp veksling mellom hardere skarelag, fokksnøflak av varierende hardhet og med litt ubunden snø i beskyttede partier.
