Weather: Monster cloud system shrouds New Zealand

A monster cloud is shrouding New Zealand on Saturday as a frontal system moves over the country.

The "long white cloud" is so massive it stretches northwest of Te Rerenga Wairua (Cape Reinga) to almost as far as Rēkohu (Chatham Islands).

"It's bringing ua [rain] to those under the front, and tuāua [showers of rain] farther north. Those south of about Te Oha-a-Maru (Oamaru) will have a dry Rāhoroi," MetService says.

"This system moves eastwards later today, which means more ua [rain] is on the way for Te Ika-a-Māui(North Island). It then moves off Aotearoa and on Rātapu, Kei te paki (it's fine on Sunday) for many, but another frontal system starts to affect southern Westland and Fiordland."

A weather map shows the next systems to arrive. MetService says a system in the Tasman Sea will bring showers to the upper North Island on Sunday afternoon - some could be heavy in Northland.

And a system to the south of Tasmania will begin to affect Fiordland from late Sunday evening.

"A heavy rain watch is in force there from 9pm Sunday," MetService says.

"Northwest winds will be strong ahead of this system and a strong wind watch has been issued for coastal Southland and Clutha, including Steward Island from 10pm on Sunday."
