Avalanche warning for region Vest-Finnmark Saturday 16.01.2021

Danger level 2 - Moderate avalanche danger

Published:
Be careful in areas with newly deposited wind slabs. The wind slabs can be overlying a persistent weak layer, and avalanches can therefor be easier to trigger and get bigger than if persistent weak layers were absent.

Avalanche problems

Persistent weak layer (slab avalanches)

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

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 15. January 2021

Dei siste dagane har det kome litt nysnø og vore vind. Dette har lagt seg opp på tidlegare vindpåverka snø med ulik hardheit, på skare eller på bakken. Generelt er det lite snø i regionen og knapt skiføre under 100 moh.

I snødekket finnast det fleire vedvarande svake lag av kantkorn, mange stadar i samband med skare. Det er også observert overflaterim der vinden ikkje har tatt.

Mountain weather

Friday 15. January 2021

5 mm precipitation, up to 10 mm in the most exposed areas. Fresh breeze from northwest. -7 °C to -2 °C at 1100 m a.s.l. Cloudy.

Saturday 16. January 2021

4-7 mm precipitation. Strong breeze from northwest, changing to breeze from the northwest during the evening. -7 °C to -2 °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

Meir nedbør og sterkare vind gjer at det vil danne seg fokksnøflak i leheng over mildvêrsgrensa. Fokksnøflaka kan ligge over vedvarande svake lag, noko som gjer at skred kan vere lettare å løyse ut og få større utbreiing enn om slike lag var fråverande. Fjernutløysing av skred er mogleg. Ved å unngå fokksnøflak unngår du skredproblem. Skredfara er størst der det har kome mest snø dei siste dagane.
