Heavy rain and gale northeasterlies across northern and central New Zealand Thursday and Friday

A rapidly deepening low is forecast to approach New Zealand from the northwest today, then to lie the west of the North Island on Thursday while continuing to move southeastwards. 

During Thursday, the low spreads a moist and strong northeast flow over northern and central New Zealand, delivering heavy rain and strong northeasterly winds to these areas.

The heaviest rain is expected in Northland, Auckland, Coromandel Peninsula, Bay of Plenty, Mount Taranaki, Marlborough, and Nelson. WARNINGS for heavy rain are now in force for these areas.

The strongest winds are expected across the upper North Island, from Taranaki to Bay of Plenty northwards, and a WARNING for severe gale northeasterlies is now in force for these areas. Note, the combination of strong winds and high tides could cause coastal inundation about eastern areas from Northland to Bay of Plenty including the Firth of Thames.

The low should cross central New Zealand on Friday bringing a period of gale westerlies to the North Island, and gale southeasterlies across the upper South Island. The low should then move away to the southeast of the country on Saturday.

People should keep up to date with the latest forecasts in case other areas are added to the WARNING.
