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.
A blue alert has been issued for people in or near the coastal and inland communities between the WA and Northern Territory border and the Mitchell Plateau.
That includes people in Wyndham, Kalumburu, Troughton Island and surrounding areas.
“Although there is no immediate danger, you need to start preparing for dangerous weather and keep up to date,” the Department of Fire and Emergency Services (DFES) warns.
Residents have been warned 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.
At around 6.30pm (CST) on Tuesday the tropical low was estimated to be about 270km northeast of Kalumburu and 335km north of Wyndham, 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, the Bureau of Meteorology says.
Gales with gusts to 100km/h may develop on the coast on Wednesday morning.
Heavy rain is also expected over the far north Kimberley region during Wednesday and Thursday.
