Avalanche warning for region Heiane Monday 17.02.2020

Danger level 3 - Considerable avalanche danger

Published:
In the high mountains, heavy snowfall and strong wind will cause unstable storm slabs. The snow pack is considerably wet in the lower areas due to high temperatures and heavy rain. The wet snow is in general stable, but loose snow avalanches may be triggered in some exposed slopes.

Avalanche problems

Wind drifted snow (slab avalanches)

You can easily trigger avalanches on some 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)

You can easily trigger avalanches on some steep slopes. Avalanches can get large enough to bury or even kill you (size 2).

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)

Sunday 16. February 2020

Snøoverflata er prega av mykje vind og nedbør dei siste dagane. Dette har gitt både tydelege fokksnøflak, skavlar og avblåste ryggar. Mildvêr natt til søndag har gitt vått snødekke opp til om lag 1100 moh.

Under nysnøen er det skare og smelteomdanna snø frå tidlegare i vinter.

Midvêr i helga har gitt høgare snøgrense, men framleis skiføre frå omlag 500 moh.

Natt til søndag var maksimumstemperaturen 0 grader på Blåsjø 1100 moh. Sør i regionen kom det 50-60 mm nedbør som regn i løpet av natta. Lengre nord omlag 25 mm.

Mountain weather

Sunday 16. February 2020

25 mm precipitation, up to 45 mm in the most exposed areas. Moderate gale from southwest. -4 °C to 3 °C at 1100 m a.s.l. Cloudy.

Monday 17. February 2020

40 mm precipitation, up to 65 mm in the most exposed areas. Gale from southwest, changing to moderate gale from the southwest during the evening. -3 °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

Mykje nysnø i fjellet og kraftig vind gir fokksnøflak i høgda. Desse flaka vil vere ustabile og lette å påverke medan vêret står på. Når temperaturen går ned blir faren for våte skred mindre, men snødekket er framleis svært vått under mildvêrsgrensa etter mange dagar med regn.
