Auckland set for more rain but warmer weather

The current cold snap enveloping much of New Zealand is set to give way
to warmer temperatures, and, in some areas, heavy rain later this week.

Weather Watch head analyst Philip Duncan said the change in weather is due to a low pressure system coming from the sub-tropics.

"This change is probably going to mean no more frost for the rest of June," Mr Duncan said.

Auckland can expect its current daytime highs of 12 degrees to increase by up to four degrees by the weekend.

He said it was still too soon to say how much rain might fall, "but the system did have potential for flooding".

Any floods are most likely to hit the western and northern areas of both islands.

Gerard Barrowu from MetService said a low will develop over the Tasman Sea but is still too far off to determine how much rain will fall.

But he confirmed a slow moving rain band will move over the country.

Mr Barrowu said forecasts are based on computer models that could quickly shift when more data becomes available.

However the MetService is moderately confident there will be heavy falls in the central North Island ranges and the Bay of Plenty.
