Avalanche warning for region Sunnmøre Saturday 28.12.2019

Danger level 3 - Considerable avalanche danger

Published:
General unstable conditions. Wet avalanches are expected. In the mountains where precipitation falls as snow, avoid new and fresh stormslabs.There is a persistent weak layer that can be triggered where the snowpack is thin.

Avalanche problems

Wet snow (slab avalanches)

You can easily trigger avalanches on some steep slopes. Avalanches can get large enough to bury a car or destroy a small house (size 3).

Water pooling in/above snow layers

Wind drifted snow (slab avalanches)

You can easily trigger avalanches on some steep slopes. Avalanches can get large enough to bury or even kill you (size 2).

Buried weak layer of new snow

Persistent weak layer (slab avalanches)

You can trigger avalanches on a few steep slopes. Avalanches can get large enough to bury or even kill you (size 2).

Below you can see a description of the current snow cover information and current weather forecast in the mountains. If your observations deviate greatly from what is described here, the warning will not necessarily apply either. Always make your own judgments or stay away from avalanche terrain.

Snow cover (in Norwegian)

Friday 27. December 2019

Snøoverflaten er generelt hard og bærende etter mildværet som gikk høyt til fjells forrige uke. På vindutsatte partier er det snøfritt eller blåst ned til gammel skare. Det er mest snø i heng mot N og Ø. Snøgrensen varierer mellom 200 og 300 moh i regionen. Det er generelt mindre snø enn normalt i fjellet.

Det finnes et svakt lag med kantkorn mot bakken i høyden. Det er også observert lag med kantkorn høyere opp i snødekket, men tilstanden til disse er ikke kartlagt etter siste mildvær.

Mountain weather

Friday 27. December 2019

Little to no precipitation. -10 °C to -2 °C at 1400 m a.s.l. Clear skies.

Saturday 28. December 2019

5 mm precipitation, up to 15 mm in the most exposed areas. Moderate gale from southwest. -5 °C to 2 °C at 1400 m a.s.l. Cloudy.

Advice

The bulletin is a planning tool and may differ from the actual situation. Always make your own evaluation. To be 100 % avalanche safe, avoid all avalanche terrain.

Avalanche risk assessment

Forholdene endrer seg. Stigende temperatur utover dagen i kombinasjon med nedbør som regn kan under mildværsgrensen resultere i naturlig utløste våte skred. I høyfjellet vil vind og ny snø legge opp ferske fokksnøflak i leområder. Der det finnes kantkornlag i snødekket kan disse påvirkes og gi skred.
