Avalanche warning for region Vest-Finnmark Thursday 02.01.2020

Danger level 3 - Considerable avalanche danger

Published:
High temperature and rain elevate the danger of wet avalanches.

Avalanche problems

Wet snow (slab avalanches)

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

Water pooling in/above snow layers

Wind drifted snow (slab avalanches)

You can trigger avalanches on some steep slopes. Avalanches can get large enough to bury a car or destroy a small house (size 3).

Poor bonding between layers in wind deposited snow

Persistent weak layer (slab avalanches)

You can trigger avalanches on some steep slopes. Avalanches can get large enough to bury a car or destroy a small house (size 3).

Buried weak layer of faceted snow above a crust

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)

Wednesday 1. January 2020

Mildvær og regn vil endre på snødekket opp til mildværsgrensen. Over denne høyden er det varierende snøoverflate etter perioder med kraftig vind.

Under gamle fokksnøflak finnes stedvis svakt lag av kantkorn. Dette ligger vekselvis under, over og mellom porøse skarelag. Skred av dette kan bli store, men laget er vanskelig å påvirke.

Naturlig utløst str2 skred i Koppartindgryta tirsdag. Antatt løsnet i siste fokksnøen uten å påvirke svake lag dypere i snødekket

Mountain weather

Wednesday 1. January 2020

2-5 mm precipitation. Breeze from west, changing to moderate gale from the southeast during the afternoon. -12 °C to -7 °C at 1100 m a.s.l. Partly cloudy.

Thursday 2. January 2020

12-16 mm precipitation. Strong breeze from southeast, changing to moderate gale from the southwest during the evening. -10 °C to -2 °C at 1100 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

Temperaturen stiger og etterhvert som nedbøren går over til regn vil faren for våte skred øke. Skred kan løsne av seg selv. Fokksnøproblemet begrenses samtidig til høgfjellet men her ventes stor pålagring lokalt.

Det er uvisst om mildværet når ned til svake lag i snødekket.
