A severe weather watch has been issued for the Coromandel Peninsula as a ‘broad complex trough is moves slowly across the North Island'.

'At this stage, there is some uncertainty as to whether rainfall accumulations will meet warning criteria, and a Watch will be maintained for the following areas,” says the MetService.

Rain is expected in the Coromandel from late this afternoon until tomorrow morning.

MetService meteorologist Georgina Griffiths says those on tank water in Auckland, Waiheke Island and Coromandel will really welcome this rain.

'As will the gardeners who are looking at that brown lawn.”

Tauranga will also see some of the rain today and tomorrow as the trough moves north.

The wind is also expected to move to the southeast in the next couple of days.
