Bay of Plenty is likely to be upgraded to a heavy rain warning tomorrow, MetService says.

A heavy rain watch remains in place for the region, including Rotorua, between 1pm tomorrow and 5am Saturday.

Periods of heavy rain were expected, which could cause surface flooding, slips and difficult driving conditions.

MetService said there was a high chance this would be upgraded to an orange warning.

An orange heavy rain warning has been issued for Coromandel Peninsula and Waikato between 11am tomorrow and 2am Saturday.

A lot of this rain will be falling on saturated soils so impacts will come about faster.

MetService said a front over the Tasman Sea spreads on to New Zealand this week, bringing heavy rain to northern and western parts of the North and South Islands.

The forecast for Bay of Plenty today is mostly cloudy with isolated showers.

On Saturday, early rain clears to cloudy weather with a chance of a shower, while Sunday is mostly fine with possible showers.

It comes after two weeks of similar rain watches and warnings for the region, described by one meteorologist as acting like a “scoop” for wild weather.

Parts of Bay of Plenty received more than 100mm of rain in 24 hours last Thursday, with flooding reported.
