Two dead after tornado lashes Perth

Two 25-year-old men who relied on electronic medical equipment have died as a tornado hit Perth suburbs, cutting power to thousands of homes.

West Australian Police said the Beaconsfield men were found dead about 7.30am on Monday.

Both had pre-existing conditions that required medical assistance.

Police said they would investigate the deaths, which were not being treated as suspicious, and prepare a report for the coroner.

Inquiries will relate to the electronic medical equipment.

The Bureau of Meteorology (BoM) confirmed the wild weather that hit Hilton, O'Connor and Claremont early on Monday was a tornado.

As well as downing power lines, it tore roofs off homes, smashed trees and sent a dinghy flying into the front yard of a house.

A BoM spokeswoman said a wind engineer had inspected damage in Hilton and concluded the tornado that hit the suburb packed wind speeds well exceeding 125km/h.
