The town of Onslow is bracing for the landfall of Tropical Cyclone Dominic today, with all areas between Mardie and Exmouth also on alert for wild weather.
The Bureau of Meteorology issued a cyclone warning early this morning for those coastal areas, as well as inland parts of the west Pilbara.
At 6am WDT the Category 2 cyclone was estimated to be 17 kilometres north northeast of Onslow and 190km west southwest of Karratha and moving south at 11 kilometres per hour, the Bureau said in its warning statement.
It says destructive gusts to 130km/hr may be experienced for a period in the Onslow region this morning.
Gales with wind gusts to 90km/hr may be experienced elsewhere within the warning area.
But the Bureau says the cyclone is expected to weaken steadily as it moves inland during the remainder of Tuesday.
Heavy rain and local flooding is expected close to the cyclone's path.
FESA-State Emergency Service says people in or near Onslow and adjacent inland communities should move to shelter, while people in or near Pannawonica should be taking action in preparation for the cyclone's arrival.
People in or near the communities of Exmouth, Nanutarra and adjacent inland communities should also be taking early precautions.
