Avalanche warning for region Lofoten og Vesterålen Thursday 26.03.2020

Danger level 2 - Moderate avalanche danger

Published:
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 here.

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).

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 25. March 2020

I høyden er snøen vindpakket med flak av varierende hardhet. Vindutsatte formasjoner er avblåste .

Lavere ned i terrenget er snødekket fuktig.

Gammelt snødekke består i stor grad av ulike skarelag og smelteomvandlet snø.

Det var observert begynnende kantkorndannelse under skarelag fra mildværet i mars. Men dette er mye sannsynlig ødelagt av senere mildvær.

Observasjoner onsdag morgen fra rundt Svolvær tilsier nysnøgrense på 250-300 moh. Mange små solutløste løssnøskred er observert i bratte heng. Smelteriller i snødekket opp til 5-600 moh.

Mountain weather

Wednesday 25. March 2020

4-6 mm precipitation. Strong breeze from southwest, changing to fresh breeze from the west during renoon. -2 °C to 2 °C at 700 m a.s.l. Cloudy.

Thursday 26. March 2020

6-10 mm precipitation. Strong breeze from southwest, changing to gale from the southwest during renoon. -2 °C to 3 °C at 700 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

Det roer seg litt med nedbør og temperaturen synker litt. Men sterk vind vil fortsatt bidra til å legge opp enkelte ferske fokksnøflak i leområder over mildværgrensen. Mest utsatt er de områder der det er kommer mest nedbør.

Kaldere vær bidrar generelt til en stabilisering av snødekket.

Sannsynligheten for naturlig utløste skred minker.
