The Bureau of Meteorology warned of significant amounts of rain in Northland, north Auckland and the Coromandel Peninsula on Thursday and Friday, and in Tairawhiti in the Bay of Plenty and northern Ruatria on Friday.
A heavy rain warning was in effect for the Northland region from 3pm Thursday to 3am Friday.
“Another low pressure system is approaching from the North Tasman Sea, bringing rain and strong winds to the upper North Island on Thursday afternoon and evening,” MetService meteorologist Luis Fernandez explained.
The low is accompanied by strong winds, and there is a moderate risk of severe northeasterly gales on Thursday in selected areas of Northland, Auckland, the Coromandel, Waikato and Waitomo, where alerts are in place.
From Friday through Saturday, high winds will tend to move west-northwest, affecting much of the upper North Island from Taranaki to Hawke’s Bay north.
Rain is also expected in Tasman and west of Marlborough northwest of the Wairau River on Friday and Saturday, with less danger expected in northern Taranaki and King Country.
Rainy and windy weather will spread rapidly across the North Island through Friday morning as the low pressure system approaches, with heavy rain and strong winds likely in parts of the upper North Island. Strong swells that can reach 6 meters are also expected on Taranaki’s north-facing coast.
“This storm is moving faster than previous weather systems that brought heavy rains and floods this year, most recently last week,” Fernandez said.
But with the ground already saturated, any more heavy rains could pose a problem, and high winds would also complicate things further.
Fernandez said Metservice does not know at this stage how damaging the rapidly changing weather system will be.
“We’ve used multiple weather forecast models, and they’re showing different options for how this weather might play out on Thursdays and Fridays into the far future,” Fernandez said. said.
A heavy rain warning has been in place since noon today for Westland in the south of Harihari. The Japan Meteorological Agency expects 90 to 130 mm of rainfall around the range, with less rain closer to the coast, with maximum rainfall of 15 to 25 mm/hour, especially during thunderstorms.
The Japan Meteorological Agency said rain is expected to spread southward as the evening progresses.
