Avalanche warning for region Vest-Telemark Sunday 02.04.2023

Danger level 2 - Moderate avalanche danger

Published:
Locally unstable conditions. A skier or a snow mobile may trigger avalanches in the fresh wind slabs, while persistent weak layers deeper in the snow in general is hard to trigger. Sun and high temperatures gives higher risk of wet loose-snow and slab avalanches in steep sun-exposed terrain.

Avalanche problems

Wind drifted snow (slab avalanches)

You can 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 some steep slopes. Avalanches are relatively harmless to people, but can knock you off balance. Can be dangerous close to terrain traps. (size 1)

Loose snow

Persistent weak layer (slab avalanches)

You can trigger avalanches 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)

Saturday 1. April 2023

Det ligger løs, tørr snø over det gamle harde snødekket. Over skoggrensen ligger det stedvis fokksnø med vekslende hardhet.

Flere runder med mildvær de siste ukene har ført til flere skarelag nedover i snødekket. Det har utviklet seg vedvarende svakt lag av kantkorn i forbindelse med disse skarelagene. Det er usikkert hvor aktive lagene er.

Det finnes også et eldre svakt lag av kantkorn ved bakken med stor utbredelse, men dette er svært vanskelig å påvirke for en person.

Kaldt og klart vær fremover kan bidra til videreutvikling av kantkorn i snødekket.

Fredag ble det meldt om et skiløperutløst str 2 flakskred i nordlig fjellside ved Store Bjørnevann i Valle. Skredet løsnet i nedføyket svak lag med nysnø.

Mountain weather

Saturday 1. April 2023

No precipitation. Strong breeze from northeast, changing to breeze from the east during the afternoon. -14 °C to -1 °C at 1100 m a.s.l. Clear skies.

Sunday 2. April 2023

No precipitation. Breeze from west. -15 °C to 1 °C at 1100 m a.s.l. Clear skies.

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 er mulig å løse ut mindre flakskred der fokksnøen er tynn eller myk.
Det ligger vedvarende svake lag nede i snødekket som generelt er vanskelig å påvirke.
Soloppvarming kan løse ut løssnøskred i bratte sørvendte fjellsider.
