MetService said a severe thunderstorm watch was in place for Northland, Auckland, the Great Barrier Island until 5pm and the Coromandel Peninsula, Waikato, Bay of Plenty, Rotorua and Taupō until 6pm.
Thunderstorms could become severe through of the afternoon, with localised downpours of 25 to 40mm/h before activity was expected to ease in the evening.
Video from MetService showed a lightning strike hitting Auckland’s 328m tall Sky Tower at around 1pm.
A reported tornado caused damage in the Manawatū region this afternoon, ripping up trees, damaging small structures, and overturning a caravan at a motor park, injuring one person.
Other watches and warnings were issued as the active low pressure system was expected to move onto central and northern parts of the country today, and move to the east of the country on Thursday.
Up to 120mm of rain was expected for Bay of Plenty including Rotorua, Gisborne/Tairawhiti north of Ruatoria and inland ranges, with highest accumulations expected east of Ōpōtiki. An orange heavy rain warning was in place for that area until midnight.
“Peak intensities 15 to 25 mm/h, but possibly 25 to 40 mm/h in localised areas.”
The top of the South Island was also set to catch some of the weather, with watches in place for Marlborough, Nelson’s inland ranges, and the Kaikōura coast.
