Christmas Day weather: North Island set for heavy rain, thunderstorms, king tide

Christmas Day is looking to be wet, forecaster MetService issuing a raft of warnings for the upper North Island.

A severe weather watch issued on Sunday morning warned heavy rain could be on the way for Northland, Auckland, the Coromandel, Waikato, Bay of Plenty and northern Gisborne.

The upset comes from a complex low and associated fronts, which are forecast to spread across the North Island from Sunday to Christmas Day before moving east on Boxing Day.

"This system is expected to bring periods of heavy rain and possible thunderstorms to northern parts of the North Island," MetService said in a statement.

Rainfall could exceed 100mm in some parts of the North Island, including eastern Northland, northern Auckland, Coromandel Peninsula, Bay of Plenty and northern Gisborne.

Wind and rain could make a dangerous combination with expected king tides on Monday evening and Christmas Day as well.

MetService has warned coastal areas could be in for some flooding, especially parts of Auckland like Tamaki Dr and the Firth of Thames.

It said the timing of the weather is still a little unpredictable and people should keep an eye on current forecasts in case anything changes.
