MetService has also forecast thunder and hailstorms for the Super City from tomorrow evening.
“All those showers we’ve had in the last couple of days? Well, they’ll strengthen,” Baillie said.
“Those winds will feel pretty bad. Auckland has a forecast high of 15C [on Sunday] but it will feel more like 8C.”
Baille said MetService would likely issue strong wind watches tomorrow, particularly about the coasts where waves could grow as high as 4m along western coastlines.
“It’s not a weekend for boaties, unfortunately. That goes for almost anywhere in New Zealand this weekend,” Baillie said.
Showers and gusts are forecast for the western parts of both islands, but eastern coasts may be “somewhat sheltered”, he said.
Winds could reach over 90km/h in exposed places - a trigger for severe gale warnings.
The National Institute of Water and Atmospheric Research (Niwa) said snow was most likely over the lower South Island. The forecaster said there was a high chance more than 3cm could fall about the Southern Alps.
“There are ‘some’ odds that snow could fall to near sea level for parts of Southland and Otago,” Niwa said.
MetService issued heavy snow watches for Otago south of Queenstown, Alexandra and Mosgiel, including Southland and Stewart Island from 3pm Staurday until 9pm Sunday.
A 45-hour heavy snow watch has also been issued for Fiordland from 9pm Friday.
Road snowfall warnings have been issued for Milford Rd and Crown Range Rd beginning at 8pm today at the earliest. Those warnings lapse at 2am tomorrow at the latest.
Temperatures around the country are forecast to remain low: Wellington has a high of 12C on Saturday and 11C on Sunday, Christchurch’s Saturday high is forecast for 10C and Sunday’s 9C and lows for both days of -2C.
“Rug up and play board games,” Baillie said.
