▲ poor visibility / whiteout — high severity
poor — visibility 240 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 — high severity
rain-on-snow: 3.1 mm at 2.8 °C; freezing level 2570 m — the signature AU hazard. Rapid strength loss, wet slides, runnels; treat steep slopes with suspicion and watch for pinwheels/roller-balls.
