Avalanche warning for region Indre Fjordane Saturday 15.02.2020

Danger level 3 - Considerable avalanche danger

Published:
Strong winds and a rapid temperature increase at night will increase the avalanche danger, especially when the wind speed is at its highest. The most prominent avalanche problems are wind slabs at higher altitudes and wet snow at lower altitudes.

Avalanche problems

Wind drifted snow (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).

Buried weak layer of new snow

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

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)

Friday 14. February 2020

Snøoverflata er prega av mykje nysnø frå onsdag og den ligg fleire stader ubunden høgt til fjells. Under nysnøen har mykje vind og nedbør siste veke lagt igjen store fokksnøflak, skavlar og avblåste rygger. Eldre snødekke er smelteomdanna etter mange rundar med mildvër tidlegare i vinter.

I fjellet vil ein kunne finne kantkornlag mellom hardare lag av skare og fokksnø. Slike lag ligg i hovudsak djupt i eldre snødekke og utgjer sannsynlegvis ikkje eit aktivt skredproblem for tida.

Torsdag vart det observert eit naturleg utløyst flakskred (str. 3) i nordvendt terreng i Stardalen i Jølster, og fleire flakskred (str. 2) i austvendt terreng i Stryn.

På Kvitenova 1400 moh på Strynefjellet bles det fredag morgon 3 m/s og det er minus 9 grader. I Hornindal har snødjupna auka med 80 cm i løpet av veka.

Mountain weather

Friday 14. February 2020

7 mm precipitation, up to 20 mm in the most exposed areas. Breeze from southwest, changing to gale from the south during the evening. -12 °C to -5 °C at 1400 m a.s.l. Partly cloudy.

Saturday 15. February 2020

4 mm precipitation, up to 10 mm in the most exposed areas. Fresh breeze from southwest, changing to gale from the southeast during the evening. -8 °C to -1 °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

Litt nedbør, sterk kuling natt til laurdag og ny vindauke laurdag kveld, dannar nye fokksnøflak, særleg i nordvendt terreng. Temperaturen stig, og våte skred kan lausne naturleg i lågareliggande terreng.
