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)

Sunday 28. February 2021

Mildværet de siste dagene har fått virke godt snødekket. Opp til ca 350 moh er snødekket gjennomfuktet og til tider råtten. Søndag var det regn opp til ca 1000 moh.

Før helgen var det ujevn fordeling av snøen i terrenget på grunn av kraftig vind.

Før mildværet var det vedvarende svake lag av kantkorn og begerkrystaller i snødekket.

Det har gått flere middels store og store naturlig utløste skred på disse lagene flere steder i regionen. Faretegn som drønn har blitt observert i lengre tid, særlig rundt og under tregrensa.

Mountain weather

Sunday 28. February 2021

20 mm precipitation, up to 30 mm in the most exposed areas. Strong breeze from southwest, changing to moderate gale from the southwest during renoon. -2 °C to 3 °C at 700 m a.s.l. Cloudy.

Monday 1. March 2021

12 mm precipitation, up to 20 mm in the most exposed areas. Moderate gale from west, changing to strong breeze from the northwest during the afternoon. -4 °C to 0 °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

Det er fortsatt stor fare for store naturlig utløste sked. Belastningen av nedbøren kan løse ut skred i vedvarende svake lag og gi støre skred.
Temperaturen synker og nysnø og vind dannner ustabile fokksnøflak.
Der snødekket fortsatt er vått vil det kunne løsne store våte flakskred
