Avalanche warning for region Romsdal Wednesday 11.12.2019

Danger level 3 - Considerable avalanche danger

Published:
The danger increases when the wind picks up. Be careful in lee areas with wind deposited snow, typically behind ridges, ribs and in gullies.

Avalanche problems

Wind drifted snow (slab avalanches)

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

Poor bonding between layers in wind deposited snow

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)

Tuesday 10. December 2019

Mildværet sist veke gjennomfukta snødekket høgt til fjells. Nysnø og vind siste dagane preger snødekket ellers med moderate mengder med fersk fokksnø av ulik hardheit. Der vinden har tatt, er det nedblåst ned til skaren.

Mildværet har truleg ikkje ødelagt lagdelinga og kantkornet i høgda, men gjort egenskapane til svake lag av kantkorn mindre potent.

Observasjon på skred i fersk fokksnø utløyst av skiløpar ved Sandtinden i Vestnes på søndag.

Mountain weather

Tuesday 10. December 2019

3 mm precipitation, up to 8 mm in the most exposed areas. Breeze from west, changing to moderate gale from the southeast during the afternoon. -12 °C to -5 °C at 1400 m a.s.l. Partly cloudy.

Wednesday 11. December 2019

5 mm precipitation, up to 10 mm in the most exposed areas. Moderate gale from south, changing to strong breeze from the southwest during renoon. -9 °C to -2 °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

Hard vind frå sør og nysnø vil gi ferske fokksnøflak i leområder i fjellet. Den harde vinden kan rive opp snødekke med mjukare snø og gjere pålagringa i leområder større. Mild luft vil truleg gi ei rask stabilisering av fokksnøen. Det er gode forhold for kantkornutvikling i snødekket, dette er på sikt lite gunstig for stabiliteten i snødekket.
