Avalanche Danger Assessment

1 Low Telen i marka er fraværende i lavlandet, og elver er fremdeles åpne også på 300 moh. Ikke ski- og knapt trugeføre, selv i høyden. Mest vindtransportert snø lengst øst i Vesterålen. Tynt snødekke i høyden med god stabilitet. Ingen observerte skredproblem. Begrenset pålagring, lite vind, og lavere temperaturer medfører ytterligere stabilisering. Forecast correct

Weather

Snow -1 °C 4 m/s from S ↑ 100% clouds Regn i lavlandet.

Tests

For lite snø til stabilitetstest.

Snow Cover

47 cm in total No snowdrift 5 cm new snow Elevation of new snow 100 masl. Snow line at 100 masl Some loose snow (1-10cm) Dry Snødekket er fordeles jevnt ved pågående snøfall, med mest over tregrensa. Til tross for høye temperaturer, så er snøen relativt tørr 500 moh. Snødekket består nå for det meste av MF, samt et delvis omdannet nysnølag på toppen.
