Avalanche warning for region Trollheimen Wednesday 01.05.2019

Danger level 2 - Moderate avalanche danger

Published:
Be careful on lee slopes with fresh wind slabs in the alpine. The danger level is low where the surface is hard.

Avalanche problems

Wind drifted snow (slab avalanches)

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

Poor bonding between layers in wind deposited snow

Wet snow (loose snow avalanches)

You can easily trigger avalanches on some 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)

Tuesday 30. April 2019

Høg temperatur i fjellet har smelta mykje snø den siste tida. Klårvêr om natta har bidrege med noko uttørking av snødekket og varierande hardleik på snøoverflata gjennom døgnet. I solsider er snøen generelt smelteomvandla, mens det i skyggevendt terreng framleis finst noko lagdelt snø over 1200 moh.
Snøgrensa er høg i S-V-vendt terreng, ellers skiføre frå 6-800 moh i N-Ø-vendt terreng, stadvis frå 1000 moh i indre strok.

Ein antek no at svakt lag kantkorn har vore nøytralisert av varme og smelting.

Mountain weather

Tuesday 30. April 2019

1-3 mm precipitation. Breeze from northwest. -1 °C to 7 °C at 1400 m a.s.l. Partly cloudy.

Wednesday 1. May 2019

12 mm precipitation, up to 25 mm in the most exposed areas. Breeze from west, changing to strong breeze from the northwest during the afternoon. -3 °C to 0 °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

Sterk vind frå NV og lokalt mykje nedbør som snø over 1200 moh vil gje stor snøtransport inn i søraustlege leområde. Her vil ein få stor pålagring og ferske fokksnøflak.

Under 1200 moh vil nedbøren kome som sludd og regn og det ventast enkelte våte laussnøskred.

Glideskred kan òg førekome på glatte og bratte fjellsider.
