Towering clouds building over Auckland, upper NI

Impressive clouds are again capturing the attention of Aucklanders, those in Waikato and other upper North Island residents as afternoon heating and high humidity continue to work together.

In Auckland a slightly breezy nor'easter has pushed cloud developments west and south of the CBD, leading to huge cloud build ups over land.
