Snow cover (in Norwegian)

Saturday 19. December 2020

Det har vært fuktig snøoverflate til topps som nå fryser til. Det ligger mest snø i vestvendt terreng. Det er mest sammenhengende snø i konkave formasjoner, ellers mye avblåst og bart.

Det er observert kantkornet snø over skarelag ved Mjølfjell og på Vikafjellet over 800-900 moh. Kantkorn finnes sannsynligvis der mildvær dannet skare tidlig i desember. Et fjernutløst skred ved Uppsete viser at dette laget kan være aktivt.

Mountain weather

Saturday 19. December 2020

15 mm precipitation, up to 30 mm in the most exposed areas. Strong breeze from south. 0 °C to 6 °C at 1100 m a.s.l. Cloudy.

Sunday 20. December 2020

8 mm precipitation, up to 18 mm in the most exposed areas. Strong breeze from south. -2 °C to 2 °C at 1100 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

Snødekket stabiliserer seg når temperaturen synker og det er mindre fare for naturlig utløste skred. Fortsatt nedbør og vind vil gi enkelte nysnøflak over snøgrensa. Der nedbøren kommer som regn kan løssnøskred løsne av seg selv. Svakt lag av kantkorn kan påvirkes der det ikke allerede er ødelagt av mildværet.
