Brace yourselves, New Zealand - strong winds and freezing air are set to swoop over the country today, causing ongoing disruption to travel with snow down to sea level in some spots.
Road closures are expected across the South Island and in the central North Island as the snow sets in, with the first snow showers arriving in Invercargill at about 6am.
It's all part of a Southern Ocean storm that's smashed into New Zealand, bringing dangerous waves, gales and bitter cold.
The cold air is coming straight off the Antarctic Shelf, according to Niwa.
Timaru was the coldest spot in the country early this morning at -0.5C.
As of 7.30am there were no closures in the central North Island but a front moving up the North Island was forecast to bring snow between 9am and midday, and again later in the afternoon.
The NZ Transport Agency warned drivers to expect snow and ice on the Desert Road and surrounding areas, and to drive with care around the Tongariro National Park.
The western coastlines of both islands can expect rain and showers today, including some squally falls with hail, according to the MetService.
Strong winds are also possible in Hawkes Bay and Wairarapa until 11am.
The MetService warned last night that the South Island could see significant disruption to travel today, with snow expected down to sea level around Southland, Clutha and southern Fiordland where a heavy snow warning is in place. Heavy snow watches are also in place in many other parts of the South Island.
Heavy snow may disrupt travel in affected areas and could damage trees and powerlines, the MetService said. Cold could also cause stress for livestock.
The surge of southerlies and southwesterlies wouldn't ease nationwide until Monday evening, Weatherwatch.co.nz said.
