Avalanche Activity

• 6. Jan. During the day (+01:00) • No avalanche activity

Snow Cover

• 95 cm in total • No snowdrift • 2 cm new snow • Elevation of new snow 550 masl. Snow line at 550 masl • Wet • Nattens nysnø er nå fuktet av regn, og det tynne snødekket nærmer seg gjennomfuktet helt opp til 700moh. Nysnø-/snøgrensen ligger lokalt på 550moh, men varierer noe i regionen. Den eldste snøpakken består av smeltefryseskare (MFcr), dekket av lag med avrundede korn (RG). Over dette et tynt lag med smeltefryseskare (MFcr). Nest øverst et lag med avrundede korn (RG), iblandet smeltefryseskare (MFcr). Øverst et lag med delvis nedbrutt snø (DG) etter nattens regn.

Avalanche Danger Assessment

• 2 Moderate • Lite snø på 700moh, men den observerte snøpakken var dels fuktig og kompakt. Stabilitetstest ikke gjennomført. Antatt mulighet for fokksnø over 1000moh, som da legger føringer for faregrad. • Vesentlig lavere temperatur kan medføre utvikling av kantkorn der det er tilstrekkelig snø, men igjen så må vi opp på +-1000moh for å eventuelt finne skredproblemet. • Forecast correct

Weather

• Drizzle • 0 °C • 9 m/s from S ↑ • 100% clouds • Møtte tåken ved 550moh.

Danger Sign

• No signs observed

Tests

• • Ingen test gjennomført.

Avalanche Problems

• Dry slab avalanche • Very difficult to trigger • 1 - Small • N, NE, E above 1000 masl

Snow Profile

• 3 cm 4F DF W, 21 cm P/1F RG/MFcr M, 5 cm K MFcr D-M, 21 cm P/1F RG D-M, 45 cm MFcr
