The first cyclone of the season, named Blake, could hit Western Australian miners in the northwest of the state.
The Bureau of Meteorology (BoM) expected the tropical cyclone to hit the eastern Pilbara region today or Wednesday.
It could intensify into a category two system.
The tropical cyclone was located 215 kilometres north of Broome by Monday Jan 6 and was tracking to move southwards, close to the Dampier Peninsula.
Gale-forced winds with gusts in excess of 125 kilometres an hour may reach inland parts of the eastern Pilbara today.
“Communities in the Kimberley, Pilbara and the Northern Territory, now is the time to get your cyclone plan in place,” BoM meteorologist Andrea Peace said.
Flood watch has been issued for coastal areas of the western Kimberley and eastern Pilbara regions.
Daily rainfall would likely total between 100 and 150 millimetres, with potential isolated, heavier falls up to 250 millimetres and thunderstorms.
