FLASH/SURFACE FLOOD WARNINGS
A band of severe thunderstorms is gaining strength off the west coast of Auckland and is set to make landfall after dark.
“There is a swarm of thunderstorms with lightening detectors picking up hundreds of flashes off shore this afternoon” says the head weather analyst at the Radio Network, Philip Duncan. “Residents from Waikato to Northland should be on high alert this evening as localised downpours could cause flash flooding, surface flooding and slips within minutes”.
Duncan expects the first set of thunderstorms to make landfall around dusk with Auckland, and especially northern regions of the city, being in the firing line after 6pm. “It could be a very wet rugby game tonight”.
The latest rain radar shows a swarm of thunderstorms 100 kilometres out to sea, stretching from Hamilton to Whangarei with the centre looking set to affect Auckland.
Drivers heading to tonight’s rugby game in Auckland should be aware that conditions could be hazardous.
Heavy showers are likely to remain over the top half of the country all night, although the risks for thunderstorms afternoon midnight will be lower.
