Tropical cyclones are low pressure systems that form over warm tropical waters and have gale force winds near the centre. They occur between November and April.

Cyclones are dangerous because they produce destructive winds, heavy rainfall with flooding and damaging storm surges that can cause inundation of low-lying coastal areas.

Heavy rainfall associated with the passage of a tropical cyclone can produce extensive flooding. 

Be prepared

Before summer it is best to be prepared for any severe weather by completing Brisbane City Council's home readiness checklist.

Approaching storm or cyclone

As a storm or cyclone is approaching:

  • listen to your local radio/TV station for official advice and warnings
  • shelter your pets and animals
  • store loose items inside (if appropriate, put outdoor furniture in your pool)
  • secure doors and windows and draw curtains
  • put valuables, medications, spare warm clothing etc. in plastic bags with your emergency kit
  • disconnect electrical items and outside TV aerials and turn off gas
  • fill bins and boats with water
  • in the case of a cyclone, fuel your car and park it undercover or cover it with tied tarpaulins/blankets.


After the storm or cyclone has passed:

  • listen to your radio and remain indoors until advised
  • do not go sightseeing
  • stay away from damaged power lines, fallen trees and flood water.
