Danger Sign

Much water in the snow Område: For kommunen. Beskrivelse: Mye varme utover dagen vil påvirke snødekket yttligere

Tests

ECTN14@19cmQ1 Medium Klokka er 10:25 i det jeg tar test. Virker å være middels stabilitet nå, men det blir stadig varmere så det vil trolig være enda letter å påvirke utover dagen

Avalanche Problems

Loose wet avalanche Loose snow Spontaneous release 3 - Large S, SW, W between 800 masl and 200 masl I retninger der sola får varme vil det være størst risiko for at det nå kan gå naturlig utløste skred

Avalanche Danger Assessment

3 Considerable Tur tidlig på dagen og da virker egentlig forholdene ganske stabile. Øverste lag på 30 cm er ganske vått og en går lett gjennom dette laget. Derfor vil det trolig også i dag kunne gå naturlige skred utover dagen. Varmt vær i vente og det vil fortsette å påvirke snødekket. Det er fortsatt mye snø enkelte plass i fjellet. Opp til 3 meter enkelte steder. Har ikke fått en profil helt i bakken siste ukene, så vanskelig å si om forholdene nærme bakken. Forecast correct

Incident
