Danger level 3 - Considerable avalanche danger

Published:

Avalanche problems

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)

Friday 16. February 2018

Det er generelt mye snø i regionen. Snødekket ventes nå å være påvirket av vind over tregrensa, etter siste dagers kraftige uvær. Under tregrensa har det ligget mye ubundet snø, men også her har vinden stedvis tatt tak.

Det er tidligere observert kantkorn rundt skarelag nede i snødekket. Dette ligger dypt og er for tiden ikke aktivt.

Det dannet seg et rimlag sist helg som kan være inntakt enkelte steder. Rimlaget ble funnet tirsdag men virker foreløpig ikke å være aktivt.

Det gikk flere naturlig utløste skred torsdag.

Det var tidvis kraftig snøfokk i høyfjellet torsdag, og vind av storm og orkan styrke.

Mountain weather

Friday 16. February 2018

4-7 mm precipitation. Fresh breeze from southeast, changing to breeze from the southwest during the afternoon. -12 °C to -4 °C at 1400 m a.s.l. Cloudy.

Saturday 17. February 2018

3-7 mm precipitation. Breeze from southeast, changing to fresh breeze from the south during the evening. -10 °C to -4 °C at 1400 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

Fokksnøen vil gradvis stabiliseres, men det vil fortsatt ta litt tid. I noen heng kan fokksnøflakene fortsatt være ustabile, og skred som løsner kan bli middels store (str 3). Stedvis har vinden dannet flak også under skoggrensa.
