Avalanche warning for region Vest-Telemark Sunday 24.02.2019

Danger level 2 - Moderate avalanche danger

Published:
Persistent weak layers are a problem at high elevations. Wet avalanches can release in steep terrain in lower areas because of sun and high temperatures. Avoid areas with visible gliding cracks, release areas and run out areas for wet snow avalanches.

Avalanche problems

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.

Buried weak layer of faceted snow beneath a crust

Wet snow (loose snow avalanches)

You can easily trigger avalanches 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)

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)

Saturday 23. February 2019

Det siste døgnet har det vore varmegrader til 2000 moh og snødekket er varmepåvirka til topps. Det har ikkje vore nedbør sidan torsdag. Under skoggrensa er snøen laus og fuktig. Over skoggrensa er det vekslande harde og mjuke flak, og det er observert fuktig snø heilt ned til bakken på 1300 moh. I høgda ligg det mindre ansamlingar av fokksnø etter vind frå N-NV.

Det har vore observert vedvarande svake lag kantkorn og nedsnødd rim i snødekket. Mildvêret siste tida har truleg nøytralisert desse laga til om lag 1000 moh. Over denne høgda må ein framleis vere merksam på at det kan vere svake lag i snødekket.

Fredag føremiddag er det litt vind frå S-SV og stigande temperatur i fjellet.

Mountain weather

Saturday 23. February 2019

No precipitation. Fresh breeze from southwest, changing to moderate gale from the southwest during the evening. -2 °C to 4 °C at 1100 m a.s.l. Partly cloudy.

Sunday 24. February 2019

No precipitation. Strong breeze from west. -3 °C to 4 °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

Synkande temperatur virkar stabiliserande på snødekket over 900 moh. Ein må dog vere merksam på at det framleis kan vere vedvarande svake lag i snødekket i høgfjellet.

I sørvendte bratte fjellsider kan ein få mindre våte laussnøskred.
