Avalanche warning for region Indre Fjordane 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 some 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

Persistent weak layer (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).

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 store mengder snø i høgfjellet dei siste dagane. Sterk vind frå sørvest har gjeve stor snøtransport av snø til nordaustlege leheng i fjellet. I lågare og i vestlegare delar har nedbøren for det meste kome som regn og snødekket er gjennomblauta.

Snøgrensa har stege litt i mildvêret, men det ligg snø ned til 4-500 moh.

Det har vore observert kantkornlag mot bakken og under skarelag høgare i snøpakken. Det er førebels ukjent korleis mildvêret har påverka dette.

Mountain weather

Tuesday 31. December 2019

16-20 mm precipitation. Strong breeze from southwest. -8 °C to -1 °C at 1400 m a.s.l. Cloudy.

Wednesday 1. January 2020

14 mm precipitation, up to 35 mm in the most exposed areas. Strong breeze from southwest. -5 °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 frå sørvest og mykje ny nedbør vil gje stor pålagring i nordvestlege leheng. Her vil det ligge ferske og eldre fokksnøflak. Skred i desse kan verte store.

Auka pålagring kan òg gje skred i vedvarande svake lag høgt i fjellet.
