The Wellington region lit up with MetService warnings on Sunday, as an “intense” weather system hit the west coast. Forecaster Hordur Thordarson from MetService said the prolonged period of storms was the result of a slow-moving and powerful weather system. “It's an intense weather system, bringing up very cold air from Antarctica and pushing it across the Tasman Sea, which is unusually warm for this time of year,” he said. The entire region faced on and off thunderstorm warnings and torrential rain on Sunday, as MetService monitored an “intense” weather system hitting the west coast. The thunderstorms were created by the many troughs in the weather system – many thunderstorms had hit New Zealand already and there were more to come overnight, Thordarson said.
