Avalanche warning for region Lyngen Thursday 05.05.2022

Danger level 3 - Considerable avalanche danger

Published:
It’s several avalanche problems that together give unstable conditions. Avalanches can occur in wet snow, in wind slabs and on persistent weak layers.

Avalanche problems

Wind drifted snow (slab avalanches)

Avalanches may release spontaneously on a few steep slopes. Avalanches can get large enough to bury a car or destroy a small house (size 3).

Buried weak layer of new snow

Wet snow (loose snow avalanches)

Avalanches may release spontaneously on some steep slopes. Avalanches are relatively harmless to people, but can knock you off balance. Can be dangerous close to terrain traps. (size 1)

Loose snow

Persistent weak layer (slab avalanches)

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

Wednesday 4. May 2022

Den siste tida har det kome mykje nysnø og det har vore ein del vind. Snøoverflata vekslar difor mellom vindpåverka snø av ulik hardheit og ubunden snø. Utover dagen kan denne bli påverka av mildvêr og sol.

I overgangen mellom gamal fuktig snø og nyare tørr snø har det danna seg eit skarelag. Høg temperaturgradient gjer at det lokalt har danna seg kantkorn rundt dette. Utviklinga og eigenskapane verkar å variere, og enkelte stadar kan det påverkast. Dei fleste stadar er korna små eller ikkje utvikla god nok til å utgjere eit skredproblem.

Mountain weather

Wednesday 4. May 2022

5 mm precipitation, up to 10 mm in the most exposed areas. Precipitation as snow. Fresh breeze from northwest, changing to breeze from the west during the evening. -10 °C to -4 °C at 1100 m a.s.l. Partly cloudy.

Thursday 5. May 2022

3-5 mm precipitation. Rain up to 700 m a.s.l during the evening. Fresh breeze from southeast, changing to strong breeze from the southwest during the evening. -14 °C to 0 °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

Vêret vil endre seg utover dagen når ein front nærmar seg. Først på dagen kan det gå våte skred der sola tek, og nokre stadar kan ein løyse ut skred i fersk fokksnø. Seinare på dagen, når temperaturane stig og vinden blir sterkare, kan det gå våte skred under mildvêrsgrensa og tørre skred i fokksnøen over mildvêrsgrensa. Enkelte stadar kan vedvarande svake lag vere godt nok utvikla til å gi skred. Om desse blir påverka av personar eller vêr kan skred bli større enn om slike lag var fråverande.
