Skredhendelse
• 5. feb 09:10–09:10 (+01:00) • Tørt flakskred • 1 - Små • Personutløst • SØ-vendt • Skredet startet på 1080 moh og sluttet på 1053 moh • Dårlig binding mellom lag i fokksnøen • 25 cm høy og 20 m bred bruddkant • Brattheng • A known danger zone in ski area, above the T Trekk we had ski cut the area twice and one skier had skied skiers left of start zone. 2nd skier skied a managed to hit the 'sweet spot' fractured 1m above the skier on the convex role.
Ulykke/hendelse
• Ski offpist • Bor i kommunen • Vært på turen mange ganger før • Alle i gruppa • Selvredning • Nedover • 1 • 0 • 0 • 0 • 0 • Ski patrol carrying out avalanche work (ski cut) before the opening of the resort. First skier skied down and was in an 'island of safety'second skier skied and realeased the avalanche. Skier was knocked off skis and fell head down the slope, transported for a couple of meters. When the avalanche slowed down, she was partially buried and able to clear her airways. 1st skier was collected by Skipatrol on scooter who was also watching the ski cutting. 1st skier was taken up above the avalanche and skied down to help the buried ski patroller. The ski cutting was carried out in a safe a professional manner, all workers had avi equipment and air bags (airbag was not deployed), 3rd patroller was on snow scooter watching from below so the buried ski patroller was reached within minutes of the incident.
Faretegn
• Skytende sprekker • Area: In this mountain side. Description: I was expecting to see more shotting cracks but I only found significant cracks at a specific location on the mountain direct east facing, 1100m convex roll.
Skredaktivitet
• 5. feb. 18-24 (+01:00) • Skavl • Ett (1). 2 - Middels. Naturlig utløst • Få bratte heng. NØ, Ø, SØ. Over ukjent moh • The cornice has been developing during this storm cycle and naturally triggered at sometime in the past 24 hours
Snødekke
• 200 cm • Moderat snøfokk • 15 cm • Mye tørr løssnø (10-30cm) • Tørr • Veldig bra • Wind has very heavily influenced the distribution of snow, ridge lines at upper elevations have been stripped to ice. Gully's and leeward features have gathered a lot of snow.
Vær
• Ikke nedbør • -5 °C • 2,5 m/s fra V → • 70% skyer
Tester
• ECTN17@26cm(RP) • Middels • At fracture layer we found very small (0.3-0.5mm) thought to be RG possible RGwp
Snøprofil
• Ø • 22° • 1 test knyttet til snøprofilen • We chose this area as it was safer than the aspect and angle that we had seen being reactive today. Time - 1415 • Vedvarende svakt lag: under flak • 14 temperaturpunkter observert
Skredfarevurdering
• I think the avalanche danger today was set correctly at 3, we saw two skier triggered avalanches on some steep unsupported slopes down 25cm, both size 1. • I think the soft wind slab will settle and we won't see the same problem tomorrow. More snow is forecast for tomorrow but with light winds, unsure of how this will bond to the surface snow. • 3 Betydelig • Varslet faregrad er riktig
