UPDATE 11.20pm Public buildings were boarded up, flights cancelled and people evacuated from outstations as the North West braces for severe tropical cyclone Rusty.
The “slow-moving and erratic” cyclone, which has been gathering power off the coast, was upgraded to a category three system last night and was forecast to be a category four by tomorrow.
People in the Pilbara and the Kimberley were warned to expect major flooding, winds of up to 200km/h and huge tides.
The Weather Bureau was unable to say precisely when or where the cyclone would make landfall.
But beneath a darkening sky in Port Hedland, locals were sandbagging shopfronts and clearing supermarket shelves of essentials.

Pardoo remains Rusty’s most likely epicentre but some model forecasts show the system stalling just before crossing the coast, tracking briefly west towards Port Hedland and moving inland late tomorrow or Thursday.
The bureau said Rusty’s slow movement would significantly strengthen the system. increasing the duration of “gale, storm or hurricane force” winds. There were also concerns about of a coastal crossing coinciding with high tide increases, resulting in a mammoth storm tide.
Kimberley emergency services boss Matt Reimer said Rusty was “chillingly similar” to the path tropical cyclone Rosita took when it hit Broome in 2000.
So far the system has hit Broome with 125mm of rain in two days.
Mr Reimer said Broome was “not out of woods” and the overnight direction of Rusty would be crucial in trying to determine where it may be heading.

A second potential cyclone was south-east of the Cocos Islands last night. There was a strong possibility the storm would develop into a tropical cyclone, to be named Sandra, by 2pm on Tuesday.
