Avalanche warning for region Hallingdal Saturday 15.04.2023

Danger level 2 - Moderate avalanche danger

Published:
Be aware of unstable wind slabs in the alpine. There can be a persistent weak layer high in the snow cover. Rain and wet snow make it easy to trigger wet avalanches in steep terrain.

Avalanche problems

Wind drifted snow (slab avalanches)

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

Buried weak layer of new snow

Wet snow (loose snow avalanches)

You can easily trigger avalanches on a few steep slopes. Avalanches are relatively harmless to people, but can knock you off balance. Can be dangerous close to terrain traps. (size 1)

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.

Mandag kom det opp 20-30 mm nedbør, mest nord i regionen. Det har vært kraftig vind fra mandag ettermiddag fra sørøst og mer påfyll av snø gjennom uka. I høyden har det dannet seg ferske fokksnøflak i leformasjoner mot nord og vest.
Under 600-800 moh er snøen fuktig etter regnværet.
Det er generelt godt med snø i de fleste himmelretninger, avblåst på utsatte plasser.

Det er flere kantkornlag i snødekket, men genrelt vanskelige å påvirke.

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

Rolig vind, men siste dagers fokksnøflak kan enkelte steder fortsatt være lett å løse ut.
Mest utsatt er heng mot nord og vestlige retninger. Vær oppmerksom på at ferske flak også kan ligge over svakt lag av kantkorn høyt i snødekket og gi ekstra ustabilitet.

I lavlandet kan det være lett å løse ut løssnøskred i bratte heng der snøen er myk og våt.
