Avalanche warning for region Ofoten Tuesday 09.01.2018

Danger level 4 - High avalanche danger

Published:
Rising temperatures and rain will weaken the snow pack. Naturally released avalanches are expected, mostly at lower elevations and in the outer parts of the region. In the alpine the wind slabs will remain unstable.

Avalanche problems

Wet snow (slab avalanches)

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

Buried weak layer of new 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)

Monday 8. January 2018

Mandag er det stor snøtransport i fjellet. Fokksnøen er ujevnt fordelt og det stedvis mye innblåst snø i leområdene.

Det gamle snødekket er stabilt og består i stor grad av skarelag og grovkornet snø etter mildværet før jul. Men et kantkornlag har utviklet seg under skaren og begynner å bli ustabilt.

Kantkorn under 'juleskaren' er begynt å blir så svakt at det kollapser.

Ikke observert skredaktivitet, men mandag ble div små testheng løst ut av en enkelt skiløper.

Mountain weather

Monday 8. January 2018

8 mm precipitation, up to 25 mm in the most exposed areas. Moderate gale from northwest, changing to breeze from the southwest during the evening. -12 °C to -6 °C at 1400 m a.s.l. Cloudy.

Tuesday 9. January 2018

20 mm precipitation, up to 35 mm in the most exposed areas. Strong breeze from southwest. -6 °C to -1 °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

Mildvær og regn svekker bindingene i snødekket i lavlandet. Her ventes det naturlig utløste skred. I høyfjellet og i indre strøk vil det bli pålagring og ustabil fokksnø i leområder.

Skredfaren ventes å nå 4-stor under mildværsgrensen.
