Avalanche warning for region Trollheimen Saturday 28.03.2020

Danger level 2 - Moderate avalanche danger

Published:
Wind and fresh snow may give instable conditions in some slopes. Be careful in lee areas with wind deposited snow, typically behind ridges, ribs and in gullies. Especially where the wind deposited slabs are thin or soft, a slab avalanche is easier to trigger. Avoid convex terrain.

Avalanche problems

New 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).

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 27. March 2020

Snøoverflaten er generelt hard etter at plussgrader nådde opp mot 1700 moh tysdag og sank mot 900 moh onsdag. Regnvêr som kom i same periode bidrog til bærande skare. Høgt til fjells er det kome ein del nysnø, særleg i Sunndal.

Eldre snøpakke er prega av kraftig vind den siste veka og fleire omgangar med mildvêr i vinter.

Mountain weather

Friday 27. March 2020

4-6 mm precipitation. Fresh breeze from southwest, changing to moderate gale from the west during the evening. -8 °C to -2 °C at 1400 m a.s.l. Cloudy.

Saturday 28. March 2020

10 mm precipitation, up to 20 mm in the most exposed areas. Moderate gale from west, changing to strong breeze from the northwest Saturday night. -12 °C to -7 °C at 1400 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

Sterk vind med aukande styrke og stadvis mykje nedbør vil gje stor snøtransport til aust- og søraustlege leområder. Her lyt ein vente seg stor pålagring og ferske fokksnøflak.

Skredproblemet er størst i sørvestlege delar av regionen der ein ventar mest nedbør.
