Strong blustery winds, squally thunderstorms and downpours are set to hammer central New Zealand and the upper North Island, including Auckland.

A strong wind warning has been put in place for Auckland including Great Barrier Island, Marlborough Sounds and Wellington with the southerly gales in the capital this afternoon expected to reach 120km/h.

Squally thunderstorms are expected across Northland, Auckland and Coromandel Peninsula this morning.

The average wind speed in Auckland had already hit 28km/h and was expected to climb to 36km/h by 10am, according to the Metservice. The rain was also expected to hit Auckland by 10am and continue through until at least 4pm.

According to MetService, these thunderstorms may bring heavy rain of 10-25mm, and strong wind gusts of 90-110km/h, along with a low risk of localised downpours of 25-40mm.

"However there is moderate risk that some of the thunderstorms may become severe, bring localised damaging gusts greater than 110 km/h and localised tornadoes, especially to northern and eastern areas."

Wind gusts of this strength can batter trees and power lines, and may make driving hazardous.

According to MetService, if any tornadoes do occur, they will be localised.


The extreme weather is thanks to a deepening low pressure system that will track quickly from the Tasman Sea across the North Island.
