Low pressure system hammering New Zealand

Drew Casper-Richardson, Saturday April 28, 2018 - 10:14 AEST

A complex low pressure system is bringing a bout of wild weather to parts of New Zealand.

The low has been marching across the Tasman sea and is now making its presence felt with Heavy Rain Warnings/Watches and Strong Wind Warnings/Watches in place for parts of the country.

Rainfall totals are expected to be highest around the Coromandel Peninsula, Bay of Plenty, Rotoru,, Nelson and Westland where 100-150mm is forecast for Saturday. Falls between 50-100mm are expected for a significant portion of the country including Auckland where 60-80mm is forecast.

The rain is expected to be heavy at times especially with the passage of thunderstorms. Rainfall rates could reach 35mm/hr in some areas including Auckland and Northland, enough to cause localised flash flooding.

The low is also generating wild winds. East to northeast winds could gust up to 120km/h in Auckland on Saturday and higher gusts can't be ruled out for exposed parts of the city. Northland and the area around Waikato and Kaimai Range could also experience severe gales.

On Sunday the low will continue to drift towards New Zealand bringing another day of heavy rain and strong winds for the North Island and northern parts of the South Island.

Conditions should start to ease from Monday however further showers and gusty winds are still expected.
