Avalanche warning for region Svartisen Thursday 16.04.2020

Danger level 3 - Considerable avalanche danger

Published:
Avoid 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 there.

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).

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)

Wednesday 15. April 2020

Tirsdag rapporteres det om 10-15 cm kram snø under 400 moh og tørr snø i høyden. Over skogen er det mye vindpåvirket snø med harde og bærende flak, mens på vindutsatte steder avblåst ned til gammelt skarelag. I skoggrensa er flakene mykere. Den siste snøen ligger i østvendte heng etter vinden først i uka.

Fra tidligere i vinter ligger det flere vedvarende svake lag med kantkorn i snødekket. Observasjoner fra forrige uke melder om at laget er fuktet og lite potent nå.

Tirsdag er det registrert opp mot 10 mm nedbør i varslingsregionen, som snø over 400 moh.

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

Fortsatt påfyll med snø, etterhvert sammen med liten kuling fra nordvest vil flytte på snø i fjellet gi ytterligere pålagring av fokksnø i lesider.

Skredfaren vil være 3 - betydelig i områder der det faller mest snø, ellers faregrad 2 der det faller mindre snø.
