Much of the North Island is basking in the sun today; but there are severe weather warnings in place in the south - with heavy rain and strong winds forecast.

MetService has issued heavy rain warnings for Buller, Westland and the headwaters of the Canterbury lakes and rivers.

The heaviest accumulation of rain is expected to be in Westland from about 3pm to the early hours of tomorrow morning.

People in the area are being told to expect between 100 to 150mm of rain to accumulate about the ranges and 50 to 80mm near the coast. There is also a possibility of thunderstorms.


The weather authority has also issued strong wind warnings for Wairarapa - including the Tararua District - Marlborough, Wellington and the Canterbury High Country.

Northwesterly winds are forecast to turn into severe gales gusting up to 120km/h in exposed areas.

A MetService spokesman warned locals to keep a close eye on weather alerts and updates.

"People are advised to keep up-to-date with the latest forecasts in case any updates are made.

"Heavy rain may cause streams and rivers to rise rapidly. Surface flooding and slips are also possible and driving conditions may be hazardous."

The National Institute of Water and Atmospheric Research said its models showed the areas at the greatest risk of feeling gusts of up to 120km/h today were on the west coast particularly in the South Island.

"Possible impacts [as a result]: localised power outages, localised wind damage, tricky travelling," Niwa said.

People in those areas were also warned about localised structural damage caused by severe gusts over the next two days, at least, and downed trees.



Despite bad weather conditions in the South Island, those in the North Island are enjoying a brighter day.

Auckland has a significant temperature high of 16C and overnight low of 10C. However, MetService was reporting Auckland's weather as feeling more like "two layers of clothing" this morning.

WeatherWatch analyst Aaron Wilkinson said it is a mostly sunny day for much of the North Island; save for a few cloudy areas for some western areas.

"Perhaps the risk of a brief shower or two, at times, about Taranaki through to Kapiti."

Wilkinson said those on the West Coast might also be in for a "rumble of thunders or two" later this evening.

High cloud with rain and showers would spread into Southland and Otago early tonight.

Just before 11am, the current extremes around the country had Christchurch the warmest place to be - with a temperature high of 18.3C. The coldest place was in Hokitika, with a temperature high of 10.3C.

The windiest spot was in Whanganui, where there were gusts of up to 35km/h.
