Weather

No precipitation -5 °C 4 m/s from NE ↙ 10% clouds

Danger Sign

Recent cracks Windblown snow >750 m, experienced slabs breaking off on SW slope. Slabs ~4cms thick, 50 x 50 cms long, wide. Slope angle ~16 degrees, so slabs broke and stopped, but would check SW facing slopes >30 degrees.

Notes

Snø red Cross ~20 cm (565 m) Hunnevatn (vegvesen webkamera 660m) ~ 30 cms +100m (760m) snø ~45 cms Snow in valley is continuous, no drifting, windblown, or ice from thawing/ freezing. Lovely snow, top 10 cms Vestlandet's powder, compacted lower section. Above 750 m wind blown snow. Wind has followed terrain, and appears to have blown from N round to NE (Cornices on S, SW facing slopes, and wind waves/scouring evidence in same areas). Some windblown icy patches higher, but good grip with metal edges. A little light on snow cover, some rocks/tree routes just below surface and easy to hit.
