Avalanche warning for region Helgeland Saturday 23.02.2019

Danger level 4 - High avalanche danger

Published:
Temperature increase and extreme amounts of rain gives high avalanche danger. Avoid avalanche terrain.

Avalanche problems

Wet snow (slab avalanches)

You can easily trigger avalanches on many steep slopes. Avalanches can get large enough to bury a car or destroy a small house (size 3).

Water pooling in/above snow layers

Wet snow (loose snow avalanches)

You can very easily trigger avalanches on many steep slopes. Avalanches can get large enough to bury or even kill you (size 2).

Loose snow

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.

Mountain weather

Friday 22. February 2019

18 mm precipitation, up to 40 mm in the most exposed areas. Strong breeze from southeast, changing to moderate gale from the southwest during the afternoon. -11 °C to 2 °C at 1100 m a.s.l. Cloudy.

Saturday 23. February 2019

10 mm precipitation, up to 20 mm in the most exposed areas. Moderate gale from southwest. 0 °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

Varselet er basert på et enklere datagrunnlag enn regionale varsler og utgis kun for faregrad 4 og 5:
Fortsatt vind fra sørlig kant, høy temperatur for årstiden og mye nedbør som vil komme som regn høyt til fjells opprettholder fortsatt stor skredfare lørdag. Det forventes at det kan gå mange naturlig utløste våte skred, og noen vil trolig få langt utløp. Skredproblemet er størst over skoggrensa hvor de største fokksnøflakene finnes.
Mildværet fortsetter å trenge dypere ned og svekke bindinger i snødekket, og kan også påvirke vedvarende svake lag høyere til fjells enn det som har vært tilfelle tidligere i vinter. Skred utløst på slike lag kan bli store eller svært store.
