Avalanche warning for region Indre Fjordane Thursday 15.02.2024

Danger level 2 - Moderate avalanche danger

Published:
Be aware that there can be pockets with persistent weak layer beneath wind deposited snow. Be careful in these areas, especially in and close to terrain traps.

Avalanche problems

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).

Buried weak layer of faceted snow near surface

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)

Wednesday 14. February 2024

Snøoverflaten er tydelig påvirket av kraftig vind helt siden fredag. Hovedsakelig fra sørøst. Vinden har flyttet snø inn i leheng og dannet fokksnøflak av varierende hardhet. Noen steder også vindpåvirket i skogen. Løs snø i godt skjermet terreng. Mildvær tidlig i februar fuktet snødekket høyt til fjells.

Kaldt klart vær i uka som var, førte til oppbyggende omdanning i snøoverflaten. Kantkorn ble funnet under fokksnøen senest 13.2. Noen steder har det også dannet seg kantkorn under det øverste skarelaget (dannet 2. feb), men det virker ikke aktivt nå.

I indre høyereliggende deler av regionen, typisk på Strynefjellet, finnes det vedvarende svake lag i form av begerkrystaller i bunn av snødekket. Disse regnes som svært vanskelig å løse ut.

Snøvær tirsdag/onsdag har gitt et dryss av nysnø i store deler av regionen. Kraftigere vind enn meldt i høyden onsdag. Observasjoner fra Gloppen tirsdag forteller om fortsatt ustabil lagdeling under fokksnøen.

Mountain weather

Wednesday 14. February 2024

15 mm precipitation, up to 25 mm in the most exposed areas. Rain up to 500 m a.s.l during renoon. Fresh breeze from southwest, changing to breeze from the southwest during the evening. -8 °C to -1 °C at 1400 m a.s.l. Cloudy.

Thursday 15. February 2024

3-6 mm precipitation. Rain up to 600 m a.s.l during the evening. Breeze from southeast, changing to fresh breeze from the southeast during the evening. -16 °C to -2 °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

Fokksnøflakene fra helga ligger stedvis på kantkorn og gjør ferdsel i skredterreng krevende. Problemet finnes hovedsakelig i heng mot nord og vest, men kan ligge i flere himmelretninger. Der fokksnøflakene er harde vil svake lag være vanskeligere å påvirke enn i mykere bundet fokksnø. Få faretegn betyr ikke at det er trygt og hvis skred først løsner kan de bli store.

Gamle vedvarende svake lag rundt skare vurderes som vanskelig å løse ut de fleste steder, men vær obs på at skaren kan ligge høyt i snødekket der nysnøen har blåst bort.
