Snow cover (in Norwegian)

Saturday 28. December 2019

Før mildværet slo inn var snøoverflaten preget av en blanding av tynn mildværsskare, hard fokksnø og noen steder 5-10 cm med løssnø.

Været fredag og særlig lørdag har endret dette bildet totalt, men hva som blir igjen etter uværet er for tidlig å si.

Under fokksnøen består snødekket av ulike skarelag og lag av smelteomvandlet snø etter tidligere mildvær.

Mountain weather

Saturday 28. December 2019

10 mm precipitation, up to 20 mm in the most exposed areas. Gale from southwest. -5 °C to 3 °C at 700 m a.s.l. Cloudy.

Sunday 29. December 2019

20 mm precipitation, up to 35 mm in the most exposed areas. Moderate gale from southwest, changing to breeze from the southwest during the afternoon. -4 °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

Mildværet med kraftig vind og regn strekker seg inn i søndagen. Det er fare for naturlig utløste skred, særlig første del av dagen. Utover dagen avtar det verste været og skredfaren vil minke etterhvert.
