Weather

5.5 °C 12 m/s from SE ↖ 100% clouds Høyt skydekke, mildt og vindfullt. 5,5 pluss på 1000m nå.

Danger Sign

Much water in the snow Område: Generelt på fjellet. Beskrivelse: Snødekket later til å drenere godt, men det er godt med vann i snøen langs bakken.

Avalanche Danger Assessment

2 Moderate Svært mildt og vindfullt vær med innslag av regn svekker bindingene i snøen nå. Nåværende snødekke har gjennomgått mye, men fortsatt mye snø igjen som siger og kan flytte på seg. Særlig høyt til fjells. Sigesprekker, skavler, utløp og terrengfeller er obspunkter nå. Nedbør vil i kveld og søndag vil øke faren. Forecast correct Varselet er fint nå.
