Avalanche warning for region Vest-Telemark Sunday 23.04.2023

Danger level 3 - Considerable avalanche danger

Published:
A persistent weak layer is present in the snow pack. Rain and high temperatures give higher risk of wet loose-snow and slab avalanches in steep terrain.

Avalanche problems

Persistent weak layer (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). Remote triggering is possible.

Buried weak layer of faceted snow beneath a crust

Wet 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).

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 22. April 2023

Mildvær sol har gjort at det nå er mye vann i snøen mange steder. Der det er klarvær og lave nattetemperaturer fryser smelteomvandlet snøoverflate til skare om natten. Skaren mykner i solhellinger og i lavere terreng utover dagen. Lokalt kan det finnes tørr snøoverflate i nordsider, men dette er bare aktuelt høyt til fjells.

Det er observert kantkorn rundt skarelag i snøpakka. Soloppvarming kan påvirke dette laget slik at det går til brudd uten annen tilleggsbelastning.

Det finnes også kantkorn ved bakken.

De siste dagene har det gått mange naturlig utløste mindre skred pga solpåvirkning. Onsdag ble det også observert et større flakskred i Valle. Dette har trolig gått på kantkornlaget i snøpakka.

Mountain weather

Saturday 22. April 2023

Little to no precipitation. Calm/light breeze from north, changing to breeze from the southeast during the evening. -4 °C to 10 °C at 1100 m a.s.l. Clear skies.

Sunday 23. April 2023

6-10 mm precipitation. Precipitation as rain. Fresh breeze from southeast, changing to fresh breeze from the southwest during the afternoon. -3 °C to 3 °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

Regnvær vil gjøre snøen gjennomvåt og dette kan gjøre at svake lag nedover i snøpakka påvirkes slik at større flakskred lett kan løses ut. Også løssnøskred kan løsne lett.
Hold god avstand til skavler og glidesprekker.
