A fast moving trough is expected to bring heavy rain, hail and possibly tornados as it moves swiftly up from Nelson to then hit Waitomo late this afternoon.
The MetService says it will first move through western parts of Buller and Nelson late this morning and early afternoon, then across Kapiti Horowhenua, and hit the north and west of Taranaki and the west of Waitomo late this afternoon and this evening.
Thunderstorms are expected to accompany this trough, and there is a moderate risk of them becoming severe with damaging wind gusts in excess of 110km/hr.
The storms may also produce localised heavy rain, hail of 5-15mm diameter, and the chance of a few small tornadoes.
The wind gusts could cause some structural damage, including trees and power lines, and
may make driving hazardous.
However, the MetService says if any tornados occur, they will only affect very localised areas. MetService will continue to monitor the situation closely for severe thunderstorm development and will issue further updates.
