Severe thunderstorms formed over southwestern WA on Monday and are a chance to develop over a large parts of the west and south of the state on Monday night and Tuesday.
At about 4pm on Monday afternoon Mandurah, south of Perth, was struck by a severe thunderstorm. The storm produced a 102km/h wind gust, strong enough to knock down trees and powerlines and unroof buildings.
The severe storms are due to a strong cold front, which is slowly crossing WA. This front is linked to an intense low south of the state and this low is generating strong winds independent of storms over a widespread area.
Severe wind related warnings have been issued for the west and south of the state.
