Danger Sign

Recent snowdrift Område: Generelt på fjellet. Beskrivelse: Moderat snødrev fra NØ

Avalanche Danger Assessment

2 Moderate Antatt god stabilitet i gammel snø og ikke noen vedvarende svake lag som ga brudd på stabilitetstester (denne plass). Fersk fokksnø fra NØ med oppsprekking rundt skien antas å være det som kan gi skred. Kom nok ca 10-20cm nysnø ila dagen og blåste fra NØ med ca 10-15m/s. Fokksnøen stabiliserer seg langsammere pga kaldere tempretur. Forecast correct

Tests

LBT@150cmQ3 God stabilitet.
