Weather: Incredible wave clouds forming over New Zealand

Incredible wave clouds are being generated as high pressure over the Tasman Sea pushes a ridge across central New Zealand.

"The visible light satellite image shows the flow very well in the formation of wave clouds in the flow, mostly generated as the winds blow over higher ground then rapidly descend in the lee of the hills," MetService said in a Facebook post. "The waves continue to the northeast as lines of wave clouds within the flow."

Another post shows an animation of the waves clouds being generated in the southwesterly flow.

The powerful flow is also generating some strong wind gusts over the North Island.

"Our weather stations at Golden Valley (just south of Coromandel Peninsula) recorded southwest gusts of 89km/h this morning while Manukau Heads had gusts of 80km/h," MetService says.
