A thunderstorm watch has been declared for Auckland.
MetService says thunderstorms are expected to develop in Auckland, Waikato and Waitomo this afternoon.
“There is a risk that some of these could be slow-moving and accompanied by downpours, 20 to 35mm/hr and hail,” the watch says.
“A severe-thunderstorm watch means conditions are favourable for severe thunderstorms in and close to the watch area.
“People in these areas should be on the lookout for threatening weather conditions and listen for possible severe-thunderstorm warnings.”
