Avalanche warning for region Tromsø Wednesday 20.04.2022

Danger level 3 - Considerable avalanche danger

Published:
Large wet avalanches can occur. The probability of avalanches is highest on sun-facing slopes. Avalanches in persistent weak layers can get very big.

Avalanche problems

Wet snow (slab avalanches)

Avalanches may release spontaneously on some steep slopes. Avalanches can get large enough to bury a car or destroy a small house (size 3).

Buried weak layer of faceted snow above a crust

Wet snow (loose snow avalanches)

Avalanches may release spontaneously on some steep slopes. Avalanches can get large enough to bury or even kill you (size 2).

Loose 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)

Tuesday 19. April 2022

I påska har det vore regn og mildt til fjelltopphøgde. Snøen er difor blitt våt, men kan ha fryst om natta der det er klarvêr.

I slutten av mars utvikla det seg eit kantkornlag rundt skarelag nede i snødekket. Dette førte til mange skred før og i starten av påska. Opp til ca. 400 moh har mildvêr gjort at dette ikkje lenger er eit problem.

Mountain weather

Tuesday 19. April 2022

No precipitation. Calm/light breeze from southwest, changing to breeze from the south during the afternoon. -2 °C to 6 °C at 700 m a.s.l. Partly cloudy.

Wednesday 20. April 2022

No precipitation. Fresh breeze from southwest. -1 °C to 7 °C at 700 m a.s.l. Clear skies.

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

Klarvêr om natta fører til gjenfrysing og stabilisering av snødekket, men når sola tek vil det tine og faren for skred og skavlbrot aukar. Våte laussnø- og flakskred kan då gå naturleg. Om skred går på vedvarande svake lag kan dei bli store til svært store. Sannsynet for skred er størst i bratte solvendte sider utover dagen.
