Avalanche warning for region Indre Troms Thursday 12.12.2019

Danger level 2 - Moderate avalanche danger

Published:
Avoid areas with newly deposited windslabs. Persistent weak layers are present in the snow cover and avalanches can be triggered in places where these layers are not protected by thick crust.

Avalanche problems

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).

Poor bonding between layers in wind deposited snow

Persistent weak layer (slab avalanches)

You can 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)

Wednesday 11. December 2019

Nedbør og sterk vind frå SØ har dei siste dagane gitt fokksnøflak over skoggrensa, medan det under skoggrensa og i skjerma områder er ubunden snø. Dette ligg på rugglete skare med smelteriller opptil 900 moh.

Det finnast kantkorn både under skarelag og ved bakken, men dette vil vere veldig vanskeleg å påverke sidan skarelaget er tjukt.

Mountain weather

Wednesday 11. December 2019

4-6 mm precipitation. Gale from southeast, changing to fresh breeze from the south during the afternoon. -16 °C to -6 °C at 1100 m a.s.l. Cloudy.

Thursday 12. December 2019

No precipitation. Strong breeze from south. -14 °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

Sterk vind har, og vil framleis, transportere snø og gi ustabile fokksnøflak i leområder som nord og vest. Desse kan stadvis ha dårleg binding til skare. Skredfara vil vere størst i områda som har fått mest snø dei siste dagane, men vil minke relativt raskt grunna gunstige temperaturar for stabilisering. Det finnast kantkornlag i snødekket men desse vil vere vanskeleg påverke grunna overliggande bærande skare.
