Points saillants

Wind slabs in the alpine are expected to be hard to trigger. Wet loose avalanches could release on steep sunny slopes if the sun peeps out.

We could see a rapidly forming instability near the surface in the alpine. A clear night could pull moisture out of the snow, leaving a weak layer of near-surface facets. This would coincide with the areas with good skiing in the alpine. Please check the snow pack before committing to steeper slopes.

Skredfaren svinger igjennom døgnet. Sola vil svekke snøoverflaten i bratte solhellinger.

I høyden er det fokksnø, men gunstige temperaturer gir rask stabilisering.

Forholdene ligger til rette for rask utvikling av svake lag nært snøoverflaten. Dette sammenfaller typisk med det gode skiføret i skyggevendte leområder med tørr og myk fokksnø i høyden. Årsaken er tørrsnø over fuktig snø, samt klarvær. Sjekk snøen nøye.

Tid på dagen og himmelretning er nøkkelen til en god skiopplevelse i påsken.

Snowpack Structure

De siste dagene er det kommet noe tørrsnø i høyden. Mildværsgrensen har svingt mellom 100 og 400 moh. Kraftig vind har trolig gitt ujevn fordeling av fokksnøen. Det er tydelige vindtegn i snøoverflaten.

Det gamle snødekket er i hovedsak stabil, grovkornet snø. Mest snø er det å finne i skålformasjoner mot øst.

Under skoggrensen på ca 300 moh er det stort sett snøfritt.

Tendency

Wind slabs in the alpine are expected to be hard to trigger.

We could see a rapidly forming instability near the surface in the alpine. A clear night could pull moisture out of the snow, leaving a weak layer of near-surface facets. This would coincide with the areas with good skiing in the alpine. For now, this is not a problem, but please check the snow pack before committing to steeper slopes.

Some wet, loose avalanches are possible on very steep, sun-exposed slopes in the afternoon.
