Snow cover (in Norwegian)

Sunday 5. May 2019

Det har kommet store mengder nedbør siste dagene, som snø fra 0-300 moh. Sterk vind fra NV har lagt opp ferske flak og store snømengder i sørøstlige leområder.
Det gamle snødekket var for det meste smelteomdannet, stabilt og fortsatt fuktig før nysnøen kom. I nordvendt terreng over 1200 moh finnes eldre lagdelinger nede i snødekket.

En antar nå at svakt lag av kantkorn er blitt nøytralisert av varme og smelting.

Observatør melder fredag om stort snøfall og 30-50 cm nysnø i forsenkninger på 900 moh øst for Storhaugen i Storlidalen. Snøen er litt kram i solvendte sider, men fortsatt kald og tørr i skyggesider til fjells. Det er gode bindinger mot gammel smelteomvandlet snøpakke.

Mountain weather

Sunday 5. May 2019

6 mm precipitation, up to 16 mm in the most exposed areas. Strong breeze from west, changing to fresh breeze from the northwest during renoon. -8 °C to -3 °C at 1400 m a.s.l. Cloudy.

Monday 6. May 2019

2-6 mm precipitation. Breeze from north. -11 °C to -4 °C at 1400 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

Roligere vær vil føre til en gradvis stabilisering av siste dagers store nysnømengder. Solinnstråling på dagen kan kortsiktig øke faren for naturlig utløste skred i bratte solsider. Først og fremst noen våte løssnøskred, men også enkelte flakskred kan forekomme.
