Snow cover (in Norwegian)

Tuesday 31. December 2019

Mildværet søndag har gitt smelteomvandlet snødekke som nå fryser igjen. Det antas at det blir skare opp til minst 600moh og antagelig høyere flere steder. Litt ny snø mandag legger seg oppå dette og over skoggrensa vil vinden flytte på snøen.

Mildværet kan ha fuktet de øverste kantkornlagene. Men dette må bekreftes ved observasjoner. Mellom skare og gammel fokksnø lenger ned i snødekket er det noen steder observert et løst lag med små kantkorn. Om mildværet har nådd ned til disse vites ikke.

Mountain weather

Tuesday 31. December 2019

5-8 mm precipitation. Strong breeze from northwest. -9 °C to -2 °C at 700 m a.s.l. Cloudy.

Wednesday 1. January 2020

9-10 mm precipitation. Breeze from west, changing to fresh breeze from the southeast during the evening. -9 °C to -2 °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

Varmere luft fra sørvest og regn gjør at det kan gå våte skred i lavlandet når temperaturen stiger. I høyden der det snør vil det bli ustabile fokksnøflak i leformasjoner.
