Avalanche warning for region Nord-Troms Saturday 27.02.2021

Danger level 3 - Considerable avalanche danger

Published:
Avoid avalanche terrain. A single skier can trigger avalanches on persistent week layers.

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 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)

Friday 26. February 2021

Det har vært lokalt sterk vind de siste dagene. Over ca 500m ligger nysnøen ujevnt fordelt i terrenget. På vindutsatte steder er det hard fokksnø eller avblåst til bakken. I skjerma områder er snøen mykere eller løs.

Lenger ned i snødekket finnes det vedvarende svake lag av kantkorn og begerkrystaller. Dette finnes enten ved bakken, i forbindelse med skare eller i lag under fokksnøen.

Mountain weather

Friday 26. February 2021

15 mm precipitation, up to 40 mm in the most exposed areas. Moderate gale from northwest. -7 °C to -3 °C at 1100 m a.s.l. Cloudy.

Saturday 27. February 2021

6 mm precipitation, up to 12 mm in the most exposed areas. Fresh breeze from west, changing to fresh breeze from the southwest during the evening. -9 °C to -5 °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

Nytt værskfite på vei, og skredfaren vil øke utover kvelden. Det kommer nedbør sammen med raskt stigende temperatur og vind.

Det ligger flere lag med kantkorn i snødekket under fokksnøen. Vær spesielt forsiktig i skoggrensen, det skal lite til for å løse ut skred på vedvarende svake lag.

Ny vindretning gjør at det vil legge seg opp fokksnøflak i nye leområder over mildværsgrensen.
