Avalanche warning for region Sunnmøre Wednesday 01.01.2020

Danger level 3 - Considerable avalanche danger

Published:
Be careful in areas with fresh windloaded snow. Avoid lee areas where a persistent weak layer can be hidden in the snow pack. Avalanches are triggered most easily where the snow pack is thin, typically close to ridges and on convex formations.

Avalanche problems

Wind drifted snow (slab avalanches)

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

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 31. December 2019

Det har kome 60 - 100 cm snø i fjellet dei siste dagane, i sterk vind frå vest-sørvest. Dette har gjeve stor snøtransport til austlege og nordaustlege leheng. I låglandet har nedbøren kome som regn på snødekket.

Det har vore observert kantkorn mot bakken i regionen i høgda. Det har òg vore observert kantkoron høgare oppe i snødekket, om tilstaden til desse laga er ikkje kartlagde etter mildvêret den siste tida.

Mountain weather

Tuesday 31. December 2019

16-20 mm precipitation. Strong breeze from southwest. -8 °C to -2 °C at 1400 m a.s.l. Cloudy.

Wednesday 1. January 2020

10 mm precipitation, up to 18 mm in the most exposed areas. Gale from southwest. -4 °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

Pågåande sterk vind og stadvis mykje ny nedbør vil gje stor snøtransport til nordaustlege leheng. Her får ein auka pålagring og ferske fokksnøflak. Det ligg òg eldre fokksnøflak mot søraust som treng tid på å stabilisere seg.
Stigande temperatur utover dagen vil svekke bindingar i snødekket og ein vil få våtare forhold opp i 1000 moh.
