Avalanche warning for region Vest-Telemark Saturday 18.03.2023

Danger level 3 - Considerable avalanche danger

Published:
Persistent weak layers buried in the snow can cause large avalanches. Remote triggering is possible. Wet avalanches can release in steep terrain in lower areas.
  • The danger is greatest until Saturday afternoon

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 (loose snow avalanches)

Avalanches may release spontaneously 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)

Friday 17. March 2023

Snøoverflaten vil nå være preget av siste dagers kraftige nedbør og vind. Snødekket over tregrensa vil i liten grad være påvirket av mildværet fredag.

Det finnes stedvis lag med kantkorn under harde, overliggende lag. Laget er ikke tilstede overalt i regionen. Det finnes svakt lag av kantkorn ved bakken, men det er vanskelig å påvirke.
På noen plasser kan det finnes nedsnødde rimkrystaller.

Fredag melder observatør fra Valle om stort snøfall, mange drønn og skytende sprekker. Særlig der nysnøflak er mykere.

Det har fredag gått flere mindre skred på vei i regionen.

Mountain weather

Friday 17. March 2023

12 mm precipitation, up to 20 mm in the most exposed areas. Rain up to 800 m a.s.l during the afternoon. Strong breeze from southeast, changing to fresh breeze from the south during renoon. -6 °C to 0 °C at 1100 m a.s.l. Cloudy.

Saturday 18. March 2023

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

Roligere vær vil gi avtagende snøskredfare mot kvelden.
Fokkksnøen fra siste dager ventes å stabiliseres gradvis når temperaturen synker.

Det kan fortsatt å være lett å løse ut, store skred på vedvarende svake lag så lenge temperaturen er høy.

Det kan løsne enkelte store våte skred tidlig på dagen.
