Avalanche warning for region Salten Friday 30.03.2018

Danger level 3 - Considerable avalanche danger

Published:
A complex situation with persistent weak layers. Avalanches are triggered most easily where the snow pack is thin, typically close to ridges and on convex formations. Remote triggering from less steep terrain is possible. Use caution on recently loaded slopes.

Avalanche problems

Persistent weak layer (slab avalanches)

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

New 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)

Thursday 29. March 2018

I skogen er det løs snø, myk vindpakket snø over skogen, hardere jo høyere man kommer. I høyfjellet er det fokksnø og ujevn snøfordeling som preget terrenget.

Det har vært noe påfyll av nysnø, men ikke så mye at det gir noe økning i skredfaren.

Vedvarende svake lag av kantkorn etter kuldeperioden feb/mars finnes flere steder over og under skarelag. Disse gir tydelige drønn og kollapser.

Onsdag er det registret et stort naturlig utløst skred ved Glomfjord.

Mountain weather

Thursday 29. March 2018

3 mm precipitation, up to 8 mm in the most exposed areas. Fresh breeze from northwest. -11 °C to -7 °C at 1400 m a.s.l. Partly cloudy.

Friday 30. March 2018

3-6 mm precipitation. Fresh breeze from west. -12 °C to -7 °C at 1400 m a.s.l. Partly 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

Fredag kan det komme litt nysnø og vind, men dette vil fort stabilisere seg på grunn av gunstige temperaturer.

De vedvarende svake lagene er fremdeles aktive og skaper et ustabilt snødekke, men også her skal det gradvis mer til å utløse skred. Husk at fravær av faretegn ikke nødvendigvis er et tegn på trygge forhold.

Mildvær i lavlandet kan gi små, våte løssnøskred.

Ferdsel i skredterreng krever kunnskap og konservativ tilnærming til terrenget.
