People in the path of Severe Tropical Cyclone Ilsa have been ordered to take shelter immediately after it intensified into a powerful category five system ahead of its final charge towards Western Australia's northern coastline.
Ilsa is about 115 kilometres north-north-east of Port Hedland and 105km north-west of Pardoo Roadhouse, with sustained winds near the centre of 215kph and wind gusts to 295kph.
People between Bidyadanga to Whim Creek, including Port Hedland — but not including Bidyadanga — and extending inland past Kumawarritji, including Nullagine, Marble Bar, Parnngurr and Telfer are now in red alert lockdown.
