Avalanche warning for region Sør-Troms Thursday 30.03.2023

Danger level 3 - Considerable avalanche danger

Published:
New snow and wind could form wind slabs on top of loose, weak layers. Last week crisp and cold conditions formed near-surface facets, and these may get buried now. Avoid steep slopes with wind slabs. Areas with a loose snow surface will have stable conditions. Naturally released avalanches are expected in the evening.
  • The danger is greatest from Thursday evening

Avalanche problems

Persistent weak layer (slab avalanches)

Avalanches may release spontaneously on some steep slopes. Avalanches can get large enough to bury or even kill you (size 2). Remote triggering is possible.

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)

Wednesday 29. March 2023

Mye løs og fin snø opp til ca 400 moh. Over dette er snøoverflaten mer vindpåvirket, men i skjerma formasjoner er det ubundet snø.

Det finnes svake lag av kantkorn under gamle skarelag i snødekket, sist observert 24. mars. Laget er vanskelig å påvirke under harde skarelag.

Mountain weather

Wednesday 29. March 2023

Little to no precipitation. Breeze from southeast, changing to fresh breeze from the northeast during the afternoon. -20 °C to -7 °C at 700 m a.s.l. Partly cloudy.

Thursday 30. March 2023

10 mm precipitation, up to 20 mm in the most exposed areas. Precipitation as snow. Fresh breeze from north, changing to gale from the northwest during the evening. -13 °C to -4 °C at 700 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

Skredfaren øker torsdag da det ventes nysnø og stedvis kraftig vind.

Den siste tidens klarvær har dannet svake, løse lag i overflaten. Trolig vil dette skape utfordringer de stedene hvor det danner seg ferske fokksnøflak over. Oppsprekkende snøoverflate er et tegn på fare. Unngå bratte heng der det ligger fersk fokksnø som sprekker opp.

Enkelte naturlig utløste skred kan forekomme, særlig mot kvelden.
