Weather: Very active thunderstorms over central and eastern North Island

A band of very active thunderstorms is moving slowly northeast over Whanganui, Taranaki, Taihape, Taumarunui and Waitomo on Sunday with heavy rain, hail, squally wind gusts and frequent lightning from 1.23pm.

MetService have issued a severe thunderstorm watch.

Although the rain, hail and wind associated with the thunderstorms may not reach severe thunderstorm criteria, the thunderstorms are producing widespread frequent lightning which could cause localised damage and affect power and internet connections, MetService says.

MetService warns to take shelter immediately if severe weather approaches.

The thunderstorms were expected to ease around 5pm.
