Official avalanche hazard — human-required

This dashboard never computes or restates an avalanche danger rating. Read the Mountain Safety Collective report before entering backcountry terrain.

▲ poor visibility / whiteout — high severity

poor — visibility 80 m (<1 km) — navigation + terrain assessment hard; whiteout is a leading AU rescue cause. Carry a compass/GPS bearing plan and known bail lines.

▲ rain on snow — watch severity

rain-on-snow: 0.2 mm at -0.6 °C; freezing level 2920 m — the signature AU hazard. Rapid strength loss, wet slides, runnels; treat steep slopes with suspicion and watch for pinwheels/roller-balls.

melt-freeze: 0.8 °C at 10:00 then -0.9 °C at 16:00 — expect bulletproof/rime crust. Crampons + ice axe; firm slips are a top AU injury cause.
