Tropical cyclone Ilsa has been downgraded to a category-three cyclone as it moves southeast through Western Australia. The storm first made landfall as a category-five cyclone, passing near Port Hedland around midnight.
Ilsa smashed into the largely uninhabited Pilbara region (the country’s most cyclone-prone region) at record-breaking speeds. It has delivered Australia’s highest ten-minute sustained wind speed record at landfall: about 218 kilometres per hour. The previous record of 194km per hour came from tropical cyclone George in 2007.
