Heavy rain and strong winds for central and northern New Zealand

This update has been issued to correct the wording in the Heavy Rain Warning for Coromandel Peninsula.

A sub-tropical low lies slow-moving to the northwest of the country, and directs a strong and humid northeast flow across central and northern New Zealand. Heavy rain with possible thunderstorms and downpours are likely for a number of regions this weekend, along with strong to gale force winds.

People are advised to keep up to date with forecasts in case any changes are made, or further areas are added.
