A spokesperson for DFES told PerthNow they have received eight calls for assistance on Tuesday morning over the potential tornado.

The Bureau of Meteorology is investigating the nature of the system to verify if this was a tornado or microburst storm.

“A microburst is a straight-line wind, and a tornado has rotating winds around it,” meteorologist Jessica Lingard told the ABC.

“They sit on a level playing field and can easily pack wind gusts of up to 100 kilometres an hour.

“It’s a smaller system but that doesn’t mean there’s such a thing as a mini-tornado: it either is (a tornado) or it isn’t.”

PerthNow has contacted BoM for comment.
