Event Qualifier — Emergency Works
Observed rainfall tested against HIRDS design depths — peak ARI by duration and gauge, river peaks with their flood-frequency ARI, and the attributed damage cost of each recorded event. Built to produce the evidence pack for an NZTA Emergency Works application.
Live mode: the current event is the register's newest row — watch it approach the 1-in-10 yr qualifying line as it accumulates.
Forecast rainfall screened into flood and slip risk per road for the next 120 hours — ranked links with their drivers, mechanism toggle between surface flooding and slope instability, ford watch, and user-asserted closure scenarios with detour consequences.
Screening, not prediction — it says where to look, never what will close.
Dashed lines — forecast. MET Norway · NRC telemetry · antecedent API (k 0.90 / 0.98)
Horizon: 3-hourly to +48 h, 6-hourly to +120 h
The routing model both instruments stand on — close any road, route the detour, see what severs and what isolates. Also available on its own, unchanged from the tool delivered July 2026.
Screening tools — not a warning service. These are network-scale screening indicators to help WiMac and KDC decide where and when to look. They are not hydraulic or flood models, carry no service-level guarantee, and do not replace official advice. MetService remains the authoritative source for weather warnings; NZTA determines Emergency Works eligibility. All outputs require manual review before any operational decision.
