Avalanche warning for region Indre Fjordane Tuesday 31.12.2019

Danger level 3 - Considerable avalanche danger

Published:
General unstable conditions. Wet avalanches are expected. In the mountains where precipitation falls as snow, avoid new and fresh stormslabs.

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

Wet snow (slab avalanches)

You can easily trigger avalanches on a few steep slopes. Avalanches can get large enough to bury a car or destroy a small house (size 3).

Water pooling in/above snow layers

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)

Monday 30. December 2019

Det har vore mykje nedbør siste døgnet, enkelte stadar over 100 mm (~1m snø). Over 900 moh har sterk vind frå sørvest gjeve stor transportert av snø inn i nordaustlege leheng i høgda. Under 900 moh har nedbøren for det meste kome som regn på snødekket.

Snøgrensa ligg på 4-500 meter.

Det er observert kantkornlag mot bakken og under skarelag i høgare i snøpakken.

Mountain weather

Monday 30. December 2019

35 mm precipitation, up to 60 mm in the most exposed areas. Moderate gale from west, changing to strong breeze from the northwest during the evening. -6 °C to 2 °C at 1400 m a.s.l. Cloudy.

Tuesday 31. December 2019

16-20 mm precipitation. Strong breeze from southwest. -8 °C to -1 °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 stadvis mykje ny nedbør vil gje stor snøtransport til austlege leheng over 800 moh. Her vil ein få stor pålagring og ferske fokksnøflak.

Auka pålagring kan òg gje skred i vedvarande svake lag.

Det er mykje vatn i snøen som treng tid på å drenere seg so ein kan framleis vente seg nokre våte skredtypar i låglandet.
