Avalanche warning for region Heiane Wednesday 20.03.2019

Danger level 2 - Moderate avalanche danger

Published:
Be careful in areas with fresh wind deposited snow. There may be pockets with a persistent weak layer beneath the wind depposited snow.

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 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.

Snow cover (in Norwegian)

Tuesday 19. March 2019

Sist helg kom det mykje snø i kombinasjon med vind frå skiftande retning. Denne snøen ligg no som fokksnø av ulik hardheit i leområder. I forsenkningar og skjerma områder ligg det lausare og mjukare snø. Snøoverflaten har vore fuktig opp til ca 700-1000 moh.

Tidlegare observert svakt kantkornlag kan være aktivt på dei høgaste toppane der mildværet ikkje fekk tak.

Mandag vart det meldt om skiløperutløst flakskred i Hunnedalen.

Det er lite eller ingen snø under ca 500 moh.

Mountain weather

Tuesday 19. March 2019

6 mm precipitation, up to 11 mm in the most exposed areas. Breeze from southeast, changing to fresh breeze from the south during the evening. -10 °C to -3 °C at 1100 m a.s.l. Partly cloudy.

Wednesday 20. March 2019

8-12 mm precipitation. Moderate gale from west, changing to strong breeze from the southwest during the evening. -3 °C to 1 °C at 1100 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 nysnø og kraftig vind vil legge opp ferske fokksnøflak i leområder. Desse flaka kan løysast ut av skiløpar. Fokksnøen kan ligge på lommer av nedføyka kantkorn som gjer det lettare å løyse ut skred, og skreda kan bli større.
