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)

Wednesday 1. January 2020

Mildvær og regn gir smelteomvandlet snødekke høyt opp. Antagelig til topps flere steder på Kvaløya. På de aller høyeste toppene vil det være tørr fokksnø i varierende hardhet.

Etter flere runder med regn og mildvær er det uvisst om de øverste kantkornlagene fortsatt eksisterer. Mellom skare og gammel fokksnø lenger ned i snødekket er trolig kantkorn inntakt.

Mountain weather

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.

Thursday 2. January 2020

18-20 mm precipitation. Fresh breeze from southeast, changing to moderate gale from the southwest during the afternoon. -2 °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

Temperaturen stiger ytterligere og etterhvert som nedbøren går over til regn vil faren for våte skred øke. Fokksnøproblemet begrenses samtidig til de høyeste toppene der nedbøren kommer som snø.

Det er uvisst om mildværet når ned til svake lag i snødekket.
