Introduction to Severe Weather Warnings
Multiple severe weather warnings have been issued for the upper North Island as the region faces periods of persistent and intense rainfall. MetService has warned of a strong and humid easterly flow that will bring downpours to the area on Tuesday, with bands of heavy rain expected to spread south on Wednesday. The warnings come as a low-pressure system originating from the tropics moves towards New Zealand, bringing with it a high risk of heavy rain and strong winds.

Auckland and Great Barrier Island are under a heavy rain watch, which is expected to be upgraded to a warning due to the high chance of heavy rain. Additionally, watches have been issued for Tasman, Canterbury, and Westland, with the watches beginning from midday on Wednesday.

Civil Defence Northland has urged residents to be prepared, saying that "a lot more heavy rain to come for our region". The organization has also warned of the risk of power outages and damage to properties.
