Avalanche warning for region Sør-Troms Sunday 05.01.2020

Danger level 3 - Considerable avalanche danger

Published:
Heavy, localized snow shower may form large unstable wind slabs in the alpine. Areas without recently formed wind slabs are expected to have safe conditions. The snowpack is very slim below treeline.

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).

Poor bonding between layers in wind deposited snow

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 4. January 2020

Fredag og lørdag har det kommet tørr nysnø i kombinasjon med vind, kraftigst fra NV-N på lørdagen.

Snødekket er trolig ujevnt fordelt med fokksnø i forsenkninger og det er avblåst ned til mildværsskaren andre steder.

Flere runder med mildvær den siste tiden har gjennomfukt snødekket omtrent til ca. 900 moh.

Det er lite snø i lavlandet.

Mountain weather

Saturday 4. January 2020

6 mm precipitation, up to 15 mm in the most exposed areas. Gale from northwest, changing to fresh breeze from the northwest during the evening. -10 °C to -3 °C at 700 m a.s.l. Cloudy.

Sunday 5. January 2020

2 mm precipitation, up to 24 mm in the most exposed areas. Fresh breeze from northwest, changing to fresh breeze from the southeast during the afternoon. -10 °C to -4 °C at 700 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

Frem til søndag formiddag kan det fortsatt komme snøbyger fra NV og det ventes lokalt store forskjeller. Utpå dagen vil vinden dreie på Ø og kraftig vind vil gi snøtransport inn nye leområder. Utvis varsomhet i områder med fersk fokksnø, disse finnes i mange himmelretninger.

Det gamle smelteomvandlet snødekket er svært stabilt.
