Avalanche warning for region Tromsø Thursday 21.04.2022

Danger level 2 - Moderate avalanche danger

Published:
Avalanches can be triggered in steep terrain where the snow is wet. Colder temperatures will have a stabilizing effect on the snowpack elsewhere. A persistent weak layer exist, but is hard to trigger.

Avalanche problems

Wet snow (loose snow avalanches)

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

Loose snow

Wet snow (slab avalanches)

You can trigger avalanches on a few 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)

Wednesday 20. April 2022

Mildvêr har gjort snøen våt til fjelltopphøgde, men med synkande temperaturar frys snøoverflata over mildvêrsgrensa. Det kan også komme litt påfyll av snø utover dagen.

I slutten av mars utvikla det seg eit kantkornlag rundt skarelag nede i snødekket. Dette førte til mange skred før og i starten av påska. Opp til ca. 400 moh har mildvêr gjort at dette ikkje lenger er eit problem.

Mountain weather

Wednesday 20. April 2022

No precipitation. Fresh breeze from southwest. -1 °C to 7 °C at 700 m a.s.l. Clear skies.

Thursday 21. April 2022

4-6 mm precipitation. Rain up to 500 m a.s.l during renoon. Fresh breeze from west. -2 °C to 3 °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

Noko kaldare vêr vil ha ei stabiliserande effekt på snødekket. Under mildvêrsgrensa kan våte skred vere lett å løyse ut og eit og anna skred kan gå naturleg, særleg der det ikkje blir nattefrost. Skred på vedvarande svake lag kan ikkje utelukkast. Over mildvêrsgrensa kan det dannast nysnøflak, men desse vil truleg finnast få stadar, bli små og stabilisere seg raskt.
