Periods of heavy rain are expected to become more persistent for a time tonight and early Wednesday morning. In the 40 hours from 8am today until midnight Wednesday expect 100 to 200mm to accumulate about the ranges, with 100 to 150mm elsewhere. Peak intensities mostly 10 to 15mm per hour, but may rise to 25 to 30mm/hr in possible thunderstorms early Wednesday morning.
People are advised that these rainfalls can cause rivers and streams to rise rapidly, surface flooding, slips and make driving conditions hazardous.
Additionally, the low moving south over the upper North Island tonight, is expected to bring a period of severe east to northeast gales with gusts up to 120 km/h to parts of Northland, Auckland and the Coromandel Peninsula, with westerly gales behind the low affecting parts of Northland.
Winds of this strength have the potential to bring down trees, damage power lines and unsecured structures.
