Avalanche warning for region Vest-Telemark Tuesday 11.04.2023

Danger level 3 - Considerable avalanche danger

Published:
Avoid lee areas with wind deposited snow at higher elevations where it snows a lot. Naturally released loose avalanches can occur around and below treeline where a lot of rain is expected.

Avalanche problems

Wind drifted snow (slab avalanches)

You can very 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)

Avalanches may release spontaneously on a few 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)

Monday 10. April 2023

Mandag kom det 15 mm nedbør. Lokalt inntil 25 mm. I høyden har det dannet seg nysnøflak. Disse kan ligge på rim som har dannet seg i helgen.
I solvendte sider er det skare på overflaten som mykner opp når temperaturen stiger utover dagen eller det regner. I nordvendte sider er snøen tørr i høyden.

Det er tidligere observert kantkorn rundt disse skarelagene, men disse virker nå vanskelig å påvirke.

Mountain weather

Monday 10. April 2023

15 mm precipitation, up to 28 mm in the most exposed areas. Rain up to 700 m a.s.l during the afternoon. Fresh breeze from southeast, changing to moderate gale from the southeast during the afternoon. -4 °C to 0 °C at 1100 m a.s.l. Cloudy.

Tuesday 11. April 2023

18 mm precipitation, up to 30 mm in the most exposed areas. Rain up to 900 m a.s.l. Fresh breeze from southeast, changing to breeze from the southwest during the afternoon. -3 °C to 1 °C at 1100 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

Det fortsetter med nedbør også tirsdag. Det ventes mest nedbør rundt Rauland og Tokke og på de høyeste toppene her ventes skredfaren å være størst. I fjellet der nedbøren kommer som snø vil fokksnøflakene bli større og kan være lette å påvirke. Det kan ikke utelukkes at rim føyker ned noen steder. Vær obs på drønn og skytende sprekker.

Der det regner kan våte løssnøskred løsne naturlig.
Faren for glideskred øker der snødekket ligger på glatt underlag. Unngå terreng under glidesprekker.
