Cyclone expected to hit WA and NT on Christmas morning A tropical cyclone is expected to form in northern Western Australia on Christmas morning with warnings issued for parts of the state and the Northern Territory. "Although there is no immediate danger, you need to start preparing for dangerous weather and keep up to date," warned the Department of Fire and Emergency Services. Residents have been told to secure or remove loose material from around their homes and ensure their emergency kits are complete. The Northern Territory Emergency Service has also advised people in affected areas to tie things down and seek shelter when conditions deteriorate. The service warned that driving conditions may be hazardous and urged people to avoid flooded roads and watercourses. The tropical low was estimated to be about 270km northeast of Kalumburu and 335km north of Wyndham at 6.30pm tonight, moving south at 4km/h towards the north Kimberley coast. The low may develop into a tropical cyclone in the next 12 to 24 hours, said the Bureau of Meteorology. Heavy rain is also expected over the far north Kimberley region on Christmas Day and Boxing Day.
