Avalanche warning for region Trollheimen Tuesday 16.05.2023

Danger level 2 - Moderate avalanche danger

Published:
Some new snow and wind at higher elevations can give slab avalanches. Generally stable conditions at lower altitudes.
  • The danger is greatest from Tuesday afternoon

Avalanche problems

New 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)

Avalanches may release spontaneously 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)

Loose snow

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)

Monday 15. May 2023

Varme, sterk sol og nedbør som regn til fjelltopphøyde preget forrige uke. Kjøligere vær utover mandag vil føre til gjenfrysing av den smelteomvandlede snøen og danne hard skare som myknes utover dagen og av sola.

Eldre svake lag i snødekket er nå de fleste steder avrundet og nøytralisert. På tykkere snødekke høyt til fjells i skyggesider kan de imidlertid fortsatt være intakte.

Observert et vått flakskred i nordvendt side i Trollheimen søndag. Naturlig utløst, vurdert til str 2-3.

Mountain weather

Monday 15. May 2023

2-4 mm precipitation. Rain up to 1700 m a.s.l. Breeze from southwest. 0 °C to 8 °C at 1400 m a.s.l. Partly cloudy.

Tuesday 16. May 2023

6 mm precipitation, up to 12 mm in the most exposed areas. Rain up to 1100 m a.s.l during the afternoon. Fresh breeze from northwest. -4 °C to 4 °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

Nysnø og vind i høyfjellet gir vinterlige forhold igjen. Det kan være lett å løse ut flakskred i myk fokksnø. Under snøgrensa vil det kalde været stabilisere snødekket.

Enkelte glideskred kan fortsatt forekomme, men sannsynligheten minker.
