Another bout of severe weather is closing in on the upper North Island, just a week after torrential rains caused flooding to northern and eastern areas.

"It's going to pick up later today," says MetService meteorologist Mark Todd.

"It's a significant system and it's going to bring another bout of severe weather to the upper North Island.

"We've gone from cold southwesterlies with the last system, and snow, to basically another deep subtropical low coming down," says Todd.

The system would bring heavy rain into Gisborne from Monday afternoon, through into Tuesday. The heavy rain would move south into Hawke's Bay from the evening.

There could also be bursts of heavier rain further to the west for places such as Northland, Auckland and Bay of Plenty.

The deepening subtropical low bringing heavy rain and severe gales is expected to be to the east of Northland by lunchtime Monday.

Winds would also continue to strengthen during the day, Todd said. There was a warning for severe gales coming off the ranges of the eastern Bay of Plenty, with gusts possibly reaching 120kmh.

There's also a chance winds could approach severe gale strength in exposed parts of Coromandel Peninsula and eastern Waikato north of Putaruru during Monday and Tuesday.

The severe weather is the result of a deepening subtropical low that has been moving south toward New Zealand. By midnight it is expected to be sitting offshore from Bay of Plenty, and make landfall somewhere in that area around midday Tuesday.

In the main centres Auckland could have southeasterly gales, gusting to 90kmh, from Monday afternoon, and showers could turn to rain, MetService said. The temperatures is expected to get to just 14 degrees Celsius. The gales and rain could last through until Tuesday afternoon.

Scattered rain is expected to develop in Wellington during Monday, with southeasterlies becoming strong and a high of 13C.

Christchurch is headed for just 10C on Monday, with light rain or drizzle and southerlies.

Patchy rain or drizzle is possible in coastal Marlborough, Canterbury, southern Westland and coastal Otago. The rest of the South Island should be dry, with Invercargill expecting sunshine, morning frosts, light winds and a 10C high.
