Avalanche warning for region Trollheimen Friday 10.02.2023

Danger level 3 - Considerable avalanche danger

Published:
Big avalanches can release by themselves or be easy to trigger in storm slabs.

Avalanche problems

Wind drifted snow (slab avalanches)

Avalanches may release spontaneously on some 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)

Thursday 9. February 2023

Snøvêr og sterk vind torsdag og utover fredagen vil gi stor snøtransport og ei vindpåverka snøoverflate. Mange stadar er det truleg hard fokksnø, men stadvis kan denne vere lettare bunden. På dei mest vindutsette stadane vil det truleg bli avblåst til bakken eller skare. Noko mildare vêr utover dagen kan gi våt snø under mildvêrsgrensa, som er meldt opptil 600 moh om kvelden.

Djupare i snødekket er det i hovudsak stabil snø. Enkelte testar har indikert svekka stabilitet rundt skarelag nede i snødekket. Dette kan skuldast kantkornlag, men desse er i tilfelle truleg lite utvikla og ikkje eit vesentleg problem no.

Mountain weather

Thursday 9. February 2023

15 mm precipitation, up to 35 mm in the most exposed areas. Rain up to 500 m a.s.l Thursday night. Gale from southwest, changing to strong gale from the west during the evening. -11 °C to -2 °C at 1400 m a.s.l. Partly cloudy.

Friday 10. February 2023

20 mm precipitation, up to 40 mm in the most exposed areas. Rain up to 600 m a.s.l during the evening. Strong breeze from west, changing to strong breeze from the south during the afternoon. -12 °C to -5 °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

Store skred kan gå naturleg og vere lette å løyse ut i fersk fokksnø. Dette skuldast lokalt mykje nysnø og vind både torsdag og fredag. Fokksnøflak kan finnast i fleire himmelretningar sidan vinden dreiar utover dagen. Hald god avstand til områder der det har blåst inn snø.
