Avalanche warning for region Sunnmøre Saturday 29.02.2020

Danger level 3 - Considerable avalanche danger

Published:
Heavy wind increases the avalanche danger. Be careful in steep terrain with wind deposited snow.

Avalanche problems

Wind drifted 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).

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 28. February 2020

Det er meir snø i regionen enn på mange år. Snømengdene er fordelt normalt med mest i aust og sørvendte leområder. Ryggar og toppar er avblåst, og det er mange stader bygd seg opp store toppskavlar. Rask uttørking av snødekket grunna stor temperaturforskjell i snøen.

Det er observert kantkornutvikling under og i eldre skarelag og i snøoverflata, men det er førebels ikkje eit skredproblem.

Sol, kaldt og lite vind fredag morgon.

Mountain weather

Friday 28. February 2020

5 mm precipitation, up to 15 mm in the most exposed areas. Breeze from south, changing to fresh breeze from the west during the afternoon. -12 °C to -5 °C at 1400 m a.s.l. Partly cloudy.

Saturday 29. February 2020

No precipitation. Fresh breeze from southeast, changing to gale from the southeast during the afternoon. -12 °C to -4 °C at 1400 m a.s.l. Partly 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

Fortsatt kald værtype gir kantkornutvikling i snødekket. Dette tørkar ut snødekket og gjer det lausare og meir flyttbart for vinden. Saman med nysnøen frå i går vil den kraftige vinden frå ettermiddagen flytte mykje snø inn i leområder. Dette gir skredproblem med store ferske fokksnøflak her. Flaka vil delvis ligge på svakare lag av kantkorn.
