A Cyclone WARNING is now current for coastal areas from Sandfire to Mardie,

At 5:00 am WST Tropical Cyclone Heidi, Category 1 was estimated to be
250 kilometres north of Port Hedland and

moving south at 20 kilometres per hour towards the coast.

Tropical Cyclone Heidi is moving in a southerly direction towards the Pilbara
coast, and is expected to produce gales with gusts to 100 kilometres per hour
in coastal areas from Sandfire Roadhouse to Port Hedland this morning,
extending west during the day, possibly as far as Mardie. Gusts could increase
