Avalanche warning for region Indre Troms Friday 09.04.2021

Danger level 3 - Considerable avalanche danger

Published:
A very tricky situation. A persistent weak layer from January is reactive and can be triggered remotely in shallow spots. Use great caution on recently wind loaded slopes. Be aware of wet avalanches in steep sun exposed slopes.

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

Wind drifted snow (slab avalanches)

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

Buried weak layer of new snow

New snow (loose snow avalanches)

on some steep slopes. Avalanches can get large enough to bury or even kill you (size 2).

Loose snow

Snow cover (in Norwegian)

Thursday 8. April 2021

Der vinden har tatt er det fokksnø av varierende hardhet i overflaten, ellers myke flak og løs snø i skjermet terreng.
Vindutsatte formasjoner er avblåst eller har gammel skare. Den siste tiden har vind lastet mye snø inn i vestvendt terreng.

I høyden over ca. 800 moh finnes det aktive vedvarende svake lag av kantkorn under skarelag. Laget ble dannet i kuldeperioden i januar.

I Tamokdalen har det gått flere store og svært store skred den siste tiden, sist onsdag.

Onsdag kveld ble det meldt om drønn i snøen ved Målselv.

Mountain weather

Thursday 8. April 2021

1-4 mm precipitation. Breeze from southwest. -14 °C to -7 °C at 1100 m a.s.l. Partly cloudy.

Friday 9. April 2021

1-3 mm precipitation. Fresh breeze from southeast. -18 °C to -7 °C at 1100 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

Krevende situasjon. Snødekket med tilhørende svake lag av kantkorn bruker litt tid på å tilvenne seg den økte belastningen av fokksnøen. Det er mulig for en enkelt skiløper å løse ut/fjernutløse store skred, enkelte steder svært store.

Store mengder fokksnø vil gradvis stabilisere seg, men kan fortsatt være lett å løse ut, særlig høyt til fjells. Vind fra SØ kan legge opp nye flak i nye himmelretninger.

Soloppvarming kan gi fare for løssnøskred. Mest utsatt er heng som ligger i le for vinden med løs, ubunden snø.
