Avalanche warning for region Vest-Finnmark Wednesday 26.02.2020

Danger level 3 - Considerable avalanche danger

Published:
Avoid lee areas with wind deposited snow, typically behind ridges, ribs and in gullies. Especially where the wind deposited slabs are thin or soft, a slab avalanche is easier to trigger there.

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)

Tuesday 25. February 2020

Mandag kom det store mengder nysnø i regionen, kombinert med kraftigere vind fra NV.

Gammelt snødekke består i stor grad av ulike skarelag og smelteomvandlet snø som er stabilt under 350 moh.

Kantkornlag er observert under skarelag fra januar, men dette ligger beskyttet under hard fokksnø og virker ikke være lett å påvirke for øyeblikket.

Det var også et naturlig utløst skred på Laslettindryggen.

Mountain weather

Tuesday 25. February 2020

6 mm precipitation, up to 14 mm in the most exposed areas. Fresh breeze from west. -14 °C to -9 °C at 1100 m a.s.l. Partly cloudy.

Wednesday 26. February 2020

8 mm precipitation, up to 20 mm in the most exposed areas. Fresh breeze from southwest, changing to gale from the southwest during the afternoon. -14 °C to -5 °C at 1100 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

Fokknsøen vil stabiliseres gradvis, prosessen går sakte grunnet lave temperaturer og det vil fremdeles kunne gå skred på disse. Påfyll av snø i kombinasjon med vind gjør at det fortsatt dannes ustabil fokksnø.

I løpet av ettermiddagen vil det passere et lavtrykk, prognosene er fortsatt noe usikre for regionen og det kan gi store variasjoner i både vindstyrke og mengde nedbør. Skredfaren vil være størst der det kommer mest nedbør.
