Avalanche warning for region Heiane Monday 20.02.2023

Danger level 3 - Considerable avalanche danger

Published:
The wind picks up and the temperature rises during the night. Wet loose avalanches are the most obvious problems at night when the rain sets in. Above the new snow line, the danger will increase in lee areas.

Avalanche problems

Wet snow (loose snow avalanches)

Avalanches may release spontaneously on many steep slopes. Avalanches can get large enough to bury or even kill you (size 2).

Loose snow

Wind drifted snow (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).

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.

Over tregrensa ligg det fersk vindpåvirka nysnø i overflata, etter snøfall i starten av helga. Under denne, er heile snøpakka smelteomdanna opp til om lag 900 moh. Vidare opp til 1200 moh er snøoverflata våt, fuktig eller gjenfrose til skare.

Det er mykje snø over 500-600 moh. Det er meir snø enn normalt for årstida i Dalane, Sirdalsheiane, Valleheiane og Kvinesdal.

Fredag vart det observert fleire ferske glidesprekkar og små våte laussnøskred i Hunnedalen i Dalane.

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

Vêromslag natt til måndag. Våte laussnøskred med korte utløpslengder kan losne naturleg i mange heng. Desse er venta frå lågareliggande lausneområde som har nok snø, frå regnet slår til om natta. Faren er størst der det regnar på tørr nysnø.

Høgare opp, der nedbøren kjem som snø, aukar faren for tørre flakskred frå leområde som vender mot nordaust, og seinare i leområde som vender mot aust.
