▲ poor visibility / whiteout — high severity
poor — visibility 380 m (<1 km) — navigation + terrain assessment hard; whiteout is a leading AU rescue cause. Carry a compass/GPS bearing plan and known bail lines.
▲ wet-loose warming — high severity
warming 1.4→8.8 °C through the day — wet-loose / point-release on sun-warmed N/NW/W aspects. Tour early, be off steep solar slopes by early afternoon.

Road and park status change fast in the alpine — open these before you drive. Chain-fit and snow closures apply to Kosciuszko Rd and the Alpine Way in winter.
Reduced speed limit · Check signage
A reduced speed limit is in place on Tantangara Rd for safety due to construction work associated with Snowy 2.0.

recent real-world trip reports
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).
