Cyclones affect Queensland, mainly along the northern coastline, each summer from November 1 to April 30. The Bureau of Meteorology allocates each cyclone a unique numeric identifier and name. The gale force winds can extend hundreds of kilometres from the cyclone centre. If the sustained winds around the centre reach 118 km/h (gusts in excess 165 km/h). then the system is called a severe tropical cyclone. These are referred to as hurricanes or typhoons in other countries.
