Earlier this week people reported mini tornadoes ripping up property near Waihi and throwing boats at Pilot Bay across the beach and road.

Wendy Dudek was terrified after a mini tornado swept through Waikino in the Karangahake Gorge on Monday night, saying she felt like she was going to be pulled out of her home.

An active front is expected to move northeast over much of cental and northern New Zealand.

There is a high risk of thunderstorms associated with the front as it travels from western areas this afternoon across the North Island overnight.

Metservice said a few of these thunderstorms might be severe and bring winds in excess of 110km/h.

A Severe Thunderstorm Watch means conditions are favourable for severe thunderstorms in and close to the watch area. People in these areas should be on the lookout for threatening weather conditions and monitor for possible Severe Thunderstorm Warnings.
