About storms in Western Australia

From May to October, southern Western Australia experiences dangerous storms, including tornados, thunderstorms, lightning, hail, flash flooding and gale-force winds.

These storms regularly cause major damage from Kalbarri to Israelite Bay, including:

  • Roof damage from loose or broken materials.

  • Fallen trees and branches.

  • Flooding caused by blocked gutters and drains.

Storms cause more damage in Australia than cyclones, earthquakes, floods and bushfires combined.
