Avalanche Danger Assessment

2 Moderate Fokksnø i høyfjellet er hovedproblemet, men det stsbiliserer seg raskt med tanke på rimelig milde tempraturer. Det skal komme en del nedbør i form av regn, men tror det vil bruke litt tid nedover i snødekket siden sol/regnsksren er såtjukk og hard før det eventuelt metter snøen ved dypere gamle skarelag. Forecast correct

Avalanche Problems

Dry slab avalanche Buried weak layer of new snow Within half a meter The collapsing weak layer is thin < 3 cm. The overlying slab is soft. Difficult to trigger 1 - Small N, NE, W, NW above 900 masl

Snow Cover

100 cm in total Moderate snow drift 0 cm new snow Snow line at 0 masl. Layered snow begins at 400 masl Some loose snow (1-10cm) Moist Det meste av snøen er i ytre strøk av regionen. Under tregrensen er begynner det å bli lite snø en del plasser.

Weather

No precipitation 4 °C 6 m/s from SE ↖ 100% clouds Forholdsvis mildt det siste døgnet. Må sikkert opp på 11/1200 moh før du nærmer deg nullisotermen. Tror ikke det har vært noe nedbør det siste døgnet.

Danger Sign

Recent snowdrift Område: Generelt på fjellet. Beskrivelse: Lett vindtransport aller høyest på fjellet, men ser ut som det er først fra 1000/1100moh. Ikke veldig mye tilgjengelig snø å flytte på.
