Avalanche warning for region Indre Sogn Tuesday 14.03.2023

Danger level 2 - Moderate avalanche danger

Published:
Be careful in areas with windslabs. A persistent weak layer of facets may be triggered, especially where the snow cover is thin.

Avalanche problems

Wind drifted 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).

Buried weak layer of new snow

Persistent weak layer (slab avalanches)

You can easily trigger avalanches on a few 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 13. March 2023

Den gamle snøoverflaten er veldig variert og går fra hard, bærende fokksnø til mykere flak. Det er mest myke flak nær skoggrensen. Noen steder finnes det nedføyket overflatekant og rim. Skare er blåst frem noen plasser. Mandag formiddag snør det lett i regionen.

Kaldt vær siste tiden har gitt oppbyggende omvandling i snødekket, særlig under skare.
Kantkorn i snødekket kan utgjøre et problem der det ligger et flak over.

Observasjon fra ca 1200moh ved Gaupne mandag forteller at det er lett å løse ut skred i den ferske fokksnøen i overgangen mellom fokk og nysnø på skare.

Mountain weather

Monday 13. March 2023

5 mm precipitation, up to 12 mm in the most exposed areas. Rain up to 300 m a.s.l during the afternoon. Fresh breeze from southeast, changing to fresh breeze from the east during the afternoon. -12 °C to -4 °C at 1400 m a.s.l. Cloudy.

Tuesday 14. March 2023

1-5 mm precipitation. Precipitation as snow. Breeze from north. -14 °C to -7 °C at 1400 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

Rolig vind og litt nysnø gir de ferske fokksnøflakene tid til gradvis stabilisering.
Der det gamle snødekket er mykt/tynt kan det være mulig å påvirke svakt lag med kantkorn som ligger høyt i snødekket. Observasjoner tyder på at det svake laget generelt ikke har god evne til bruddforplantning, men det kan være lokale variasjoner.
