Avalanche warning for region Lyngen Tuesday 25.12.2018

Danger level 3 - Considerable avalanche danger

Published:
The snowpack is very unstable. Avoid areas with wind-deposited snow. It is also possible to trigger avalanches in a persistant weak layer in old snow found in bowls and gullies.

Avalanche problems

New 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).

Persistent weak layer (slab avalanches)

You can very 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)

Monday 24. December 2018

Det har snødd siden søndag. Før nysnøen lå det mest snø i nordvendte leformasjoner etter vind fra stort sett sørlig retning den siste tiden. Snødekket var ellers generelt hardt, men med mykere flak i beskyttede leformasjoner. Snødekket er ellers preget av tynn skare opp til ca. 600-700 moh. Det er generelt lite snø.

Begynnende kantkorn ved bakken er observert ved Lyngseidet og begynnende kantkorndannelse mellom skare og gamle fokksnøflak opp til 800 moh.

Noe rim på overflaten er observert både ved Lyngseidet og i Lavangsdalen, men over skoggrensa har vinden ødelagt det de fleste steder.

Mountain weather

Monday 24. December 2018

4-8 mm precipitation. Fresh breeze from southwest, changing to breeze from the southwest during the evening. -13 °C to -6 °C at 1400 m a.s.l. Partly cloudy.

Tuesday 25. December 2018

10 mm precipitation, up to 15 mm in the most exposed areas. Strong breeze from southeast, changing to fresh breeze from the southwest during renoon. -12 °C to -4 °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

Mer nysnø og mer vind vil øke størrelsen på fokksnøansamlingene i nordvendte leformasjoner. Der fokksnøflakene legger seg oppå rimkrystaller eller områder med velutviklede kantkornkrystaller vil flakene kunne bli veldig ustabile.
