An active low-pressure system is bringing unsettled weather to central and northern parts of the country today, but is expected to move east on Thursday and pass close to the Chatham Islands later that night and into early Friday morning.

The system is forecast to deliver heavy rain, thunderstorms, and localised downpours, along with strong winds across affected regions. Warnings and watches are in force, and authorities are urging people to stay up to date with the latest forecasts.

Heavy rain warning – orange

Areas affected: Bay of Plenty (including Rotorua) and Gisborne/Tairāwhiti north of Ruatoria

Period: 11am to 11pm, Wednesday

Forecast: After easing earlier this morning, another period of heavy rain is expected from late morning through tonight. Rainfall totals of 60 to 90mm are likely, with the highest accumulations east of Ōpōtiki. Peak intensities could reach 15 to 25mm per hour, and up to 40mm per hour in localised areas. Thunderstorms and downpours remain possible.

Impact: Rapid rises in streams and rivers, surface flooding, slips, and hazardous driving conditions are possible.

Action: Residents are advised to clear drains and gutters, avoid low-lying areas, and drive cautiously.

While the chance of upgrading to a red warning is considered low, the risk of severe weather impacts remains significant.
