A severe weather warning, a severe weather watch and a thunderstorm watch is in place for many places in the North Island.

Remnants of Cyclone Donna is expected to pass just east of Northland and Auckland on Friday before moving away to the east.

'A period of heavy northerly rain is expected over much of central and northern New Zealand ahead of the front,” says the MetService.

'For parts of Bay of Plenty and the ranges of Gisborne, 200 to 250mm of rain may accumulate, while lower lying parts of Bay of Plenty may receive 100 to 140mm of rain.”

The MetService says localised downpours with intensities of 25 to 40mm per hour are likely in these areas, and other North Island areas as detailed in the severe weather watch.

'This amount of rain will cause rivers and streams to rise rapidly, and may cause surface flooding and slips. Driving conditions will also be hazardous.”

There is a moderate risk of severe thunderstorms and/or downpours about Northland, northern and eastern parts of Auckland, including Great Barrier Island, Coromandel Peninsula and Bay of Plenty from the early hours of Friday morning through to Friday afternoon.

'These severe thunderstorms and/or downpours are expected to produce rainfall rates of 25 to 40mm per hour or possibly more. Rainfall of this intensity can cause flash flooding, especially about low-lying areas and may also lead to slips.”
