Avalanche Problems

Loose wet avalanche Loose snow Spontaneous release Possible 2 - Medium Widespread steep slopes N, NE, E, SE, S, SW, W, NW below 1200 masl

Wet slab avalanche Water pooling in/above snow layers Within a meter Spontaneous release Possible 3 - Large Widespread steep slopes N, NE, E, SE, S, SW, W, NW below 1200 masl

Weather

Rain 2 °C 7 m/s from W → 100% clouds

Snow Cover

200 cm in total No snowdrift 0 cm new snow Layered snow begins at 700 masl Other Wet Smelteriller vertfall opp til 900 m oh. På 900 er ikkje heile snøpakka våt enda, men det er mykje vatn i snøen. Så det er truleg berre tidsspørsmål

Avalanche Danger Assessment

3 Considerable Fukten har komme godt ned i snødekke, litt vanskelig å vurdere sannsynet for naturlege skred. Kanskje oppvarming har skjedd såpass gradvis at snøen har fått tid til å tilpasse seg og me difor sålangt i dag ikkje har fått så mykje skred.

Danger Sign

Much water in the snow Område: For kommunen. Beskrivelse: Tidvis kraftig regn, vatn over skarelag i profil

Tests

CTN Good Ikkje utslag på CT, men vått og vatn over skarelag

Avalanche Activity

14. Feb. During the day (+01:00) Loose wet avalanche Several (6-10). 2 - Medium. Spontaneous release Widespread steep slopes. N, NE, E, SE, S, SW, W, NW Såg fleire mindre skred på køyretur til obstur.
