Avalanche warning for region Indre Troms Friday 30.03.2018

Danger level 3 - Considerable avalanche danger

Published:
Dangerous avalanche conditions as large amount of new snow needs to settle. Persistent weak layers are still reactive to triggering. Avoid recently loaded slopes in the alpine.

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 some steep slopes. Avalanches can get large enough to bury a car or destroy a small house (size 3).

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

Det har kommet en del snø i regionen den siste tiden, lokalt ligger det rundt 20-40 cm snø. Over tregrensa er snødekket mer preget av vind og det er ikke like mye løssnø her.

Torsdag har vært stor snøtransport og forflyttning av snø.

Det er observert flere lag med kantkorn rundt skarelag etter kuldeperioden februar-mars.

Tirsdag er det observert ferske flakskred, trolig i forbindelse med vindøkningen midt på dagen.

Det er fortsatt mye drønn fra snødekket som følge av kantkornlaget kollapser.

Mountain weather

Thursday 29. March 2018

3-6 mm precipitation. Strong breeze from northwest, changing to fresh breeze from the northwest during the evening. -13 °C to -6 °C at 1100 m a.s.l. Cloudy.

Friday 30. March 2018

3-7 mm precipitation. Fresh breeze from west. -11 °C to -6 °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

Økende vind kan frakte store mengder snø inn i leområder. Her kan de overlaste vedvarende svake lag og det kan gå store naturlig utløste skred.

Bygevær gjør at det lokalt kan komme mer snø enn varslet, men også mindre.
