Avalanche warning for region Trollheimen Thursday 02.05.2019

Danger level 2 - Moderate avalanche danger

Published:
At higher altitudes avoid areas with wind-deposited snow, typically behind ridges, ribs and in gullies. Keep distance to areas with gliding cracks.

Avalanche problems

Wind drifted snow (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).

Poor bonding between layers in wind deposited snow

Glide avalanches

Not given Not given Not given

Wet snow/melting near the ground

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 2. May 2019

Det har kome 20-30 cm snø siste døgnet i sterk vind frå NV i høgfjellet, og det har lagt seg opp ferske flak i søraustlege leområder. I lågareliggande område har nedbøren kome som regn på snødekket.
Det eldre snødekket er for det meste smelteomdanna og stabilt, men det finst eldre lagdelingar i skyggevendt terreng over 1200 moh.
Trass i synkande snøgrense er det ikkje skiføre før 6-800 moh.

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

Mountain weather

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.

Thursday 2. May 2019

14 mm precipitation, up to 25 mm in the most exposed areas. Fresh breeze from northwest, changing to fresh breeze from the west during the evening. -10 °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

Pågåande vind frå NV-V og lokalt mykje nedbør som snø over 400 moh vil gje snøtransport inn i søraustlege og austlege leområde. Her vil ein få auka pålagring og ferske fokksnøflak.
Skredproblemet og skredfaren er hovedsakleg knytt til dei høgreliggande områda der nysnøen legg seg på eldre snø.
