Avalanche warning for region Indre Sogn Saturday 28.12.2019

Danger level 3 - Considerable avalanche danger

Published:
Fresh wind deposited snow and rising temperatures may cause naturally released avalanches. Storm slabs will most likely be dry during the first part of the day, before the snow turns wet in the afternoon.

Avalanche problems

Wind drifted snow (slab avalanches)

You can easily trigger avalanches on many steep slopes. Avalanches can get large enough to bury or even kill you (size 2).

Buried weak layer of new snow

Wet snow (slab avalanches)

You can easily trigger avalanches on many steep slopes. Avalanches can get large enough to bury or even kill you (size 2).

Water pooling in/above snow layers

Persistent weak layer (slab avalanches)

You can trigger avalanches on a few steep slopes. Avalanches can get large enough to bury a car or destroy a small house (size 3).

Below you can see a description of the current snow cover information and current weather forecast in the mountains. If your observations deviate greatly from what is described here, the warning will not necessarily apply either. Always make your own judgments or stay away from avalanche terrain.

Snow cover (in Norwegian)

Friday 27. December 2019

Snøoverflaten består bristende skare og høyt til fjells hard fokksnø, stedvis med et lite lag nysnø oppå. Snøen er forholdsvis jevnt fordelt i terrenget, og det er litt mindre snø enn normalt for årstiden.

Det ble observert overflaterim på hard underlag i Sogndalsdalen torsdag.

Mountain weather

Friday 27. December 2019

No precipitation. -11 °C to -4 °C at 1400 m a.s.l. Clear skies.

Saturday 28. December 2019

15 mm precipitation, up to 25 mm in the most exposed areas. Strong breeze from southwest. -7 °C to 0 °C at 1400 m a.s.l. Cloudy.

Advice

The bulletin is a planning tool and may differ from the actual situation. Always make your own evaluation. To be 100 % avalanche safe, avoid all avalanche terrain.

Avalanche risk assessment

Nysnø og vind fra SV gir mye ustabil fokksnø i leheng, skred kan løsne naturlig der fokksnøen legger seg over nedføyket rim. Utover dagen vil stigende temperatur gi overgang fra tørre skred til våte skred, skred kan løsne naturlig. Det skal generelt mye til for å påvirke kantkornlag ved bakken.
