Avalanche warning for region Trollheimen Thursday 09.02.2023

Danger level 3 - Considerable avalanche danger

Published:
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

Vêret har variert mykje dei siste dagane, og det same har snøoverflata. Mildvêr har stadvis nådd opp til ca. 900 moh og tæra på snøen. Sterk vind har transportert snø i høgda.

Utover torsdagen vil det bli kaldare, kome nedbør og det skal vere sterk vind. Fokksnø av varierande hardheit vil då finnast stadig lavare i terrenget. I enkelte godt skjerma områder kan det vere ubunden snø.

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

Wednesday 8. February 2023

No precipitation. Moderate gale from southwest, changing to strong gale from the southwest during the afternoon. -8 °C to 0 °C at 1400 m a.s.l. Partly cloudy.

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.

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

Skred kan gå naturleg og vere lette å løyse ut i fersk fokksnø. Dette skuldast at det skal komme nysnø og vere sterk vind. Hald god avstand til leheng ved ferdsel i fjellet. Skredfara vil vere størst i områda som får mest nysnø.
