Two aggressive fronts are set to merge over Auckland city this afternoon and in the past 10 minutes MetService has issued their second only Severe Thunderstorm Warning – this time for Whangarei, Kaipara and Rodney district, including Helensville.
Head weather analyst Philip Duncan says the rain radars looks a bit like the ‘perfect storm’. “We’re seeing one band of torrential rain moving in from the north east, prompting rain warnings earlier today, combined with a band of aggressive thunderstorms morning in from the north west – the two will merge over Auckland this afternoon and evening”.
Mr Duncan says the live and free lightning tracker has fired into life in the past hour, with 430 lightning strikes detected over Northland to Waikato in the past 60 minutes.

Mr Duncan says there is an increased risk of flooding due to the slow movement of the fronts.

We had a pretty impressive display in Whangarei. Heavy rain for a sustained period and a few very loud thunder claps which resulted in some surface flooding. I think had it rained for just a bit longer at its heaviest, flooding would have been much worse. National News Weather reports for Whangarei for the last 3 days have been way off, so nice for them to get it right. ; -)

and are we likely to get much of the rain and thunder storms.

At this stage, not really. Te Aroha is one the fringes of the main rain band and the thunderstorms are confined to north of Auckland and south east of Matamata.
