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.

BOM station observations, never blended with the forecast. Arrows: change vs the same station ~3 h ago (measured, no model). No sensor sits on the Main Range itself. Station names link to BOM's own obs pages.

▲ poor visibility / whiteout — high severity

poor — visibility 320 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: 2.3 mm at 3.9 °C; freezing level 2360 m — the signature AU hazard. Rapid strength loss, wet slides, runnels; treat steep slopes with suspicion and watch for pinwheels/roller-balls.

The morning read ends with the safety net, not just the weather. Chains must be carried in Kosciuszko NP in winter (4WD/AWD exempt); Kosciuszko Rd is closed Perisher→Charlotte Pass (oversnow only). The full pre-trip checklist lives in the repo (docs/FIELD-NOTES.md).
