Avalanche forecast for Hardanger Thursday 2019-02-14

3
Considerable
Published:

A persistant weak layer is present in the snow pack. Rain and high temperatures give higher risk of wet slag and loose-snow avalanches in steep terrain. Be aware of cornice falls.

Wet snow (slab avalanches)

Water pooling in/above snow layers

Avoid avalanche release and run out areas. Wet snow avalanches tend to release spontaneously. Stability decreases when the snow surface gets wet and soft. Timing is important.

Spontaneous release
Some steep slopes
Possible

Loose snow

Avoid avalanche release and run out areas. Wet snow avalanches tend to release spontaneously. Timing is important. Stability decreases when the snow surface gets wet and soft.

Tett tåke/lavt skydekke gjør det for tiden vanskelig å gjøre fareobservasjoner på makronivå. Så det blir med hva man kommer over nær skisporet. Krysset over en ganske bred sigesprekk over en konveks (trolig fra foregående døgn med 20 mm nedbør. Økt masse har ført til sig på et av de svakere lagene i snødekket. Dette bekrefter for meg tilstedeværelsen av svakt lag som påvist tidligere. I dag, torsdag, er det kun kommet et par millimeter nedbør, så vannet har fått tid å drenere ut av snødekket i stor grad. Men rundt et av skarelagene er det relativt fuktig fremdeles.
