South Island

Heavy snow is expected to fall on one of the South Island's most iconic roads while damaging tornados and huge swells could hit the North Island on Thursday. 

A heavy snow watch has been issued for the Canterbury high country down to just south of Queenstown until 6am on Friday. 

The area could see a brief period of heavy snow above 700 metres. 

MetService has issued a road snowfall warning for Crown Range Road, Lindis Pass (SH8) and Milford Road (SH94) and is predicting half a metre of snow to fall on the three roads.

Waka Kotahi NZ Transport Agency said the Milford Road (SH94) will close at 4:30pm on Thursday from the East Gate to West Gate and they'll attempt to reopen it when conditions allow.

A severe thunderstorm watch has been issued for Nelson, Buller and Westland until 9am on Thursday. 

MetService warned the area could see one or two small or damaging tornadoes while localised heavy rain, hail and squally wind gusts are also expected. 

"Between midnight Wednesday and 9am Thursday, there is a risk that a few of these thunderstorms could be severe with large hail, damaging wind gusts in excess of 110 km/h, and one or two small or damaging tornadoes," MetService said. 

"Large hail can cause significant damage to crops, orchards, vines, glasshouses and vehicles, as well as make driving conditions hazardous. 

"Wind gusts of this strength can cause some structural damage, including to trees and power lines, and may make driving hazardous. If any tornadoes occur, they will only affect very localised areas."

A heavy rain watch has been issued for Tasman, the northern Marlborough Sounds and Westland south of Okarito, which could bring periods of heavy rain and possible thunderstorms. 

"More significant snow is then expected to affect the road from late this evening to late Friday evening, where 40 to 50cm of snow may accumulate above about 600 metres with lesser amounts down to about 400 metres."

North Island 

The North Island doesn't escape the bad weather with a severe thunderstorm watch issued for Waitomo, Taranaki, Wanganui, Manawatu, Kapiti-Horowhenua and Wellington until 2pm on Thursday.

MetService said scattered thunderstorms are expected to affect the western parts of the North Island south of Waikato until Thursday evening bringing localised heavy rain, hail and squally wind gusts.

"There is a risk that a few of these thunderstorms could be severe south of Raglan with damaging wind gusts in excess of 110 km/h, and one or two small or damaging tornadoes," MetService said. 

"Wind gusts of this strength can cause some structural damage, including to trees and power lines, and may make driving hazardous. If any tornadoes occur, they will only affect very localised areas."

A heavy rain warning has been issued for Horowhenua south of Levin, Wellington north of the Ngauranga Gorge and the Tararua Range until 6pm on Thursday. 

MetService said these areas could expect up to 100mm of rain, which could cause streams and rivers to rise rapidly. Surface flooding and slips are also possible and driving conditions may be hazardous.

A heavy swell warning has been issued for the Kapiti-Porirua Coast and as far north as Otaki with waves rising to as high as 4.5 metres.
