A waterspout that ripped through a Perth car park has been caught on camera knocking down brick walls and creating havoc.

Video shows the vortex-like shape ripping through the carpark before knocking down a supermarket loading dock on Sunday.

A person can be heard saying "absolute destruction. It whipped everything up."

Debris was left scattered through the carpark.

Weatherzone senior meteorologist Brett Dutschke told 9news the waterspout was formed in heavy showers offshore before making its way over land.

"The weather set-up was conductive for this given the unstable atmosphere."

No one was believed to be injured.
